1.  Introduction

   "There's a freedom about the Internet: As long as we accept the rules
   of sending packets around, we can send packets containing anything to
   anywhere."  [Berners-Lee]

   "The Internet isn't value-neutral, and neither is the IETF."
   [RFC3935]

   The evergrowing ever-growing interconnectedness of the Internet and society
   increases the impact of the Internet on the lives of individuals.
   Because of this, the design and development of the Internet
   infrastructure also
   has have a growing impact on society.  This has led
   to a broad recognition that human rights [UDHR] [ICCPR] [ICESCR] have
   a role in the development and management of the Internet [HRC2012] [UNGA2013]
   [NETmundial].  It has also been argued that the Internet should be
   strengthened as a human rights an enabling environment for human rights [Brown].

   This document aims to (1) expose the relation relationship between protocols
   and human rights, (2) propose possible guidelines to protect the
   Internet as a
   human-rights-enabling an enabling environment for human rights in future
   protocol development, in a manner similar to the work done for Privacy Considerations in
   privacy considerations [RFC6973], and to (3) increase the awareness awareness, in
   both the human rights community and the technical community on community, of the
   importance of the technical workings of the Internet and its impact
   on human rights.

   Document authors who want to apply this work to their own can go
   directly to Section 6 of this document.

   Open, secure secure, and reliable connectivity is necessary (although not
   sufficient) to exercise human rights such as freedom of expression
   and freedom of association [FOC], as defined in the Universal
   Declaration of Human Rights [UDHR].  The purpose of the Internet is
   to be a global network of networks that provides unfettered
   connectivity to all users users, and for any content [RFC1958].  This
   objective of stimulating global connectivity contributes to the
   Internet's role as an enabler of human rights.  The Internet has
   given people a platform to exchange opinions, gather information, opinions and gather information;
   it has enabled people of different backgrounds and genders to
   participate in the public
   debate, debate; it has also allowed people to
   congregate and organize.  Next to that, the strong commitment to
   security [RFC1984] [RFC3365] and privacy [RFC6973] [RFC7258] in the
   Internet's architectural design
   contribute contributes to the strengthening of
   the Internet as a human rights an enabling environment. environment for human rights.  One could
   even argue that the Internet is not only an enabler of human rights, rights
   but that human rights lie at the
   basis base of, and are ingrained in, the
   architecture of the networks that make up the Internet.  Internet
   connectivity increases the capacity for individuals to exercise their rights,
   rights; the core of the Internet, Internet -- its architectural design -- is
   therefore closely intertwined with the human rights framework
   [CathFloridi].  The quintessential link between the Internet's
   infrastructure and human rights has been argued by many.  [Bless]  [Bless1],
   for instance instance, argues that, 'to that "to a certain extent, the Internet and its
   protocols have already facilitated the realization of human rights,
   e.g., the freedom of assembly and expression.  In contrast, measures
   of censorship and pervasive surveillance violate fundamental human rights.'  [Denardis15]
   rights."  [DeNardis15] argues that 'Since "Since the first hints of Internet
   commercialization and internationalization, the IETF has supported
   strong security in protocol design and has sometimes served as a
   force resisting protocol-enabled surveillance features.' features."  By doing
   so, the IETF enabled the manifestation of the right to privacy,
   through the Internet's infrastructure.  Additionally, access to
   freely available information gives people access to knowledge that
   enables them to help satisfy other human rights, rights; as such such, the
   Internet increasingly becomes a pre-condition precondition for human rights rather
   than a supplement.

   Human rights can be in conflict with each other, such as the right to
   freedom of expression and the right to privacy.  In such cases cases, the
   different affected rights need to be balanced.  In order to  To do this this, it is
   crucial that the rights impacts on rights are clearly documented in order to
   mitigate the potential harm.  Making  This research aims to ultimately contribute
   to making that process tangible and practical for protocol developers is what this research aims to
   ultimately contribute to.
   developers.  Technology can never be fully equated with a human
   right.  Whereas a specific technology might be a strong enabler of a
   specific human right, it might have an adverse impact on another
   human right.  In this case case, decisions on design and deployment need
   to take this into account.

   The open nature of the initial technical design and its open
   standards, as well as developments like open source, fostered freedom
   of communication.  What emerged was a network of networks that could
   enable everyone to connect and to exchange data, information information, and
   code.  For many, enabling such connections became a core value.
   However
   However, as the scale and the commercialization of the Internet grew,
   topics like access, rights rights, and connectivity are have been forced to
   compete with other values.  Therefore, important human rights enabling characteristics of
   the Internet that enable human rights might be degraded if they're
   not properly defined, described described, and protected as such.  And, the other
   way around,  Conversely,
   not protecting human right enabling characteristics that enable human rights could also
   result in (partial) loss of functionality and connectivity, and along
   with other inherent parts of the Internet's architecture of networks.
   New protocols, particularly those that upgrade the core
   infrastructure of the network, should be designed to continue to
   enable fundamental human rights.

   The IETF has produced guidelines and procedures to ensure and
   galvanize the privacy of indiduals individuals and security of the network in
   protocol development.  This document aims to explore the possibility
   of the development of developing similar procedures for guidelines for human rights
   considerations to ensure that protocols developed in the IETF do not
   have an adverse impact on the realization of human rights on the
   Internet.  By carefully considering the answers to the questions
   posed in the Section 6 part of this document, document authors should be
   (1) able to produce a comprehensive analysis that can serve as the
   basis for discussion on whether the protocol adequately protects
   against specific human rights threats, threats and (2) potentially stimulate
   authors stimulated
   to think about alternative design choices.

   This document was developed within the framework of the Human Rights
   Protocol Considerations (HRPC) Research Group, based on discussions
   on the HRPC mailing list (Section 9); this document was also
   extensively discussed during HRPC sessions.  This document has
   received eleven in-depth reviews on the mailing list, and it received
   many comments from inside and outside the IRTF and IETF communities.

2.  Vocabulary used Used

   In the discussion of human rights and Internet architecture architecture, concepts
   developed in computer science, networking, law, policy-making policy-making, and
   advocacy are coming together [Dutton],[Kaye],[Franklin], [Dutton] [Kaye] [Franklin] [RFC1958].
   The same concepts might have a very different meaning and
   implications in other areas of expertise.  In order to foster a
   constructive interdisciplinary debate, debate and minimize differences in
   interpretation, the following glossary is provided, building provided.  It builds as
   much as possible on existing definitions, and where these definitions; when definitions were not
   available in IETF documents, definitions have been developed.

   Accessibility  Full were taken from other
   Standards Development Organizations (SDOs) or academic literature.

   Accessibility:  "Full Internet Connectivity Connectivity", as described in [RFC4084]
      [RFC4084], to provide unfettered access to the Internet Internet.

      The design of protocols, services services, or implementation implementations that provide
      an enabling environment for people with disabilities.

      The ability to receive information available on the Internet

   Anonymity Internet.

   Anonymity:  The condition of an identity being unknown or concealed.
      [RFC4949]

   Anonymous concealed
      [RFC4949].

   Anonymous:  A state of an individual in which an observer or attacker
      cannot identify the individual within a set of other individuals
      (the anonymity set).  [RFC6973]

   Authenticity set) [RFC6973].

   Authenticity:  The property of being genuine and able to be verified
      and be trusted.  [RFC4949]

   Blocking  the trusted [RFC4949].

   Blocking:  The practice of preventing access to resources in the
      aggregate [RFC7754].  Both blocking and filtering can be
      implemented at the level of "services" (web hosting or video
      streaming, for example) or at the level of particular "content."
      [RFC7754]

   Censorship  technical "content"
      [RFC7754].

   Censorship:  Technical mechanisms, that include including both blocking and
      filtering, that certain political or private actors around the
      world use to block or degrade Internet traffic.  For further
      details on the various elements of Internet censorship censorship, see [hall]
      [Hall].

   Censorship resistance resistance:  Methods and measures to mitigate Internet
      censorship.

   Confidentiality

   Confidentiality:  The property that data is not disclosed to system
      entities unless they have been authorized to know the data. data
      [RFC4949].

   Connectivity

   Connectivity:  The extent to which a device or network is able to
      reach other devices or networks to exchange data.  The Internet is
      the tool for providing global connectivity [RFC1958].  Different
      types of connectivity are further specified in [RFC4084].

      The combination of the end-to-end principle, interoperability, distributed
      architecture, resilience, reliability reliability, and robustness
      are in
      combination constitute the enabling factors that result in
      connectivity to to, and on on, the Internet.

   Content agnosticism agnosticism:  Treating network traffic identically regardless
      of content.

   Decentralized

   Decentralized:  Implementation or deployment of standards, protocols protocols,
      or systems without one single point of control.

   End-to-End

   End-to-end principle:  The principle that application-specific
      functions should not be embedded into the network and thus stay at
      the end-points:

      in endpoints.  In many cases, especially when dealing with
      failures, the right decisions can only be made with the
      corresponding application-
      specific application-specific knowledge, which is available
      at the end-points endpoints not in the network.

      The end-to-end principle is one of the key architectural
      guidelines of the Internet.  The argument in favor of the end-to-
      end
      end-to-end approach to system design is laid out in the
      fundamental paper papers by Saltzer, Reed, and Clark [Saltzer] [Clark].
      In it, these papers, the authors argue in favor of radical
      simplification: systems system designers should only build the essential
      and shared functions into the network, as most functions can only
      be implemented at network end points. endpoints.  Building features into the
      network for the benefit of certain
      applications, applications will come at the
      expense of others.  As such, as a in general system designers should
      attempt to steer clear of building anything into the network that
      is not a bare necessity for its functioning.  Following the
      end-to-end principle is crucial for innovation, as it makes
      innovation at the edges possible without having to make changes to
      the network, and it protects the robustness of the network.  Various
      [RFC2775] further elaborates on various aspects of end-to-end connectivity are further
      elaborated on in [RFC2775].

   Federation
      connectivity.

   Federation:  The possibility of connecting autonomous and possibly
      centralized systems into a single system without a central
      authority.

   Filtering  the

   Filtering:  The practice of preventing access to specific resources
      within an aggregate [RFC7754].

   Heterogeneity  The

   Heterogeneity:  "The Internet is characterized by heterogeneity on
      many levels: devices and nodes, router scheduling algorithms and
      queue management mechanisms, routing protocols, levels of
      multiplexing, protocol versions and implementations, underlying
      link layers (e.g., point-to-point, multi-access links, wireless,
      FDDI, etc.), in the traffic mix and in the levels of congestion at
      different times and places.  Moreover, as the Internet is composed
      of
      independent autonomous organizations and Internet internet service providers, each
      with their own separate policy concerns,there concerns, there is a large
      heterogeneity of administrative domains and pricing structures. structures."
      [FIArch]

      As a result, per [FIArch], the heterogeneity principle proposed in
      [RFC1958] needs to be supported by design.  [FIArch]

   Human rights

   Human rights are principles rights:  Principles and norms that are indivisible,
      interrelated, unalienable, universal, and mutually
      reinforcing that reinforcing.
      Human rights have been codified in national and international
      bodies of law.  The Universal Declaration of Human Rights [UDHR]
      is the most well-known document in the history of human rights.
      The apirations aspirations from this documents [UDHR] were later codified into treaties such
      as the International Covenant on Civil and Political Rights
      [ICCPR] and the International Covenant on Economic, Social and
      Cultural Rights [ICESCR], after which signatory countries were
      obliged to reflect them in their national bodies of law.  There is
      also a broad recognition that not only states have an obligations vis a vis
      vis-a-vis human rights, but non-state actors do so as well.

   Integrity

   Integrity:  The property that data has not been changed, destroyed,
      or lost in an unauthorized or accidental manner. manner [RFC4949].

   Interoperable  A property of a documented standard or protocol which
      allows different independent implementations to work with each
      other without any restriction on functionality.

   Internationalization (i18n) (i18n):  The practice of making protocols,
      standards, and implementations usable in different languages and
      scripts (see Localization). Section 6.2.12 ("Localization")).

      "In the IETF, "internationalization" 'internationalization' means to add or improve the
      handling of non-ASCII text in a protocol" [RFC6365].

      A different perspective, more appropriate to protocols that are
      designed for global use from the beginning, is the definition used
      by W3C: the World Wide Web Consortium (W3C) [W3Ci18nDef]:
      "Internationalization is the design and development of a product,
      application or document content that enables easy localization for
      target audiences that vary in culture, region, or language."
      [W3Ci18nDef]

      Many protocols that handle text only handle one charset (US-
      ASCII),
      (US-ASCII), or they leave the question of encoding up to local
      guesswork (which leads, of course, to interoperability problems)
      [RFC3536].  If multiple charsets are permitted, they must be
      explicitly identified [RFC2277].  Adding non-ASCII text to a
      protocol allows the protocol to handle more scripts, hopefully all of the ones
      useful
      scripts in use in the world.  In today's world, that is normally
      best accomplished by allowing Unicode encoded in UTF-8 only,
      thereby shifting conversion issues away from ad hoc choices.

   Interoperable:  A property of a documented standard or protocol that
      allows different independent implementations to work with each
      other without any restriction on functionality.

   Localization (l10n) (l10n):  The practice of translating an implementation
      to make it functional in a specific language or for users in a
      specific locale (see Internationalization).

      Localization is the act of tailoring an application for a
      different language or script language, script, or culture.  Some internationalized
      applications can handle a wide variety of languages.  Typical
      users only understand a small number of languages, so the program
      must be tailored to interact with users in just the languages they
      know.  The major work of localization is translating the user
      interface and documentation.  Localization involves not only
      changing the language interaction, interaction but also other relevant changes changes,
      such as display of numbers, dates, currency, and so on.  The
      better internationalized an application is, the easier it is to

      Privacy is a broad concept relating to the protection of
      individual or group autonomy and the relationship between an
      individual or group and society, including government, companies companies,
      and private individuals.  It is often summarized as "the right to
      be left alone" alone", but it encompasses a wide range of rights rights,
      including protections from intrusions into family and home life,
      control of sexual and reproductive rights, and communications
      secrecy.  It is commonly recognized as a core right that underpins
      human dignity and other values such as freedom of association and
      freedom of speech.

      The right to privacy is also recognized in nearly every national
      constitution and in most international human rights treaties.  It
      has been adjudicated upon both by both international and regional
      bodies.  The right to privacy is also legally protected at the
      national level through provisions in civil and/or criminal codes.

3.  Research Questions

   The Human Rights Protocol Considerations (HRPC) Research Group (hrpc) in the
   Internet Research Taskforce Task Force (IRTF) embarked on its mission to answer
   the following two questions questions, which are also the main two questions
   which
   that this documents document seeks to answer:

   1.  How can Internet protocols and standards impact human rights,
       either by
       either enabling them or by creating a restrictive environment?

   2.  Can guidelines be developed to improve informed and transparent
       decision making
       decision-making about the potential human rights impact of protocols? protocols on human
       rights?

4.  Literature and Discussion Review

   Protocols and standards are regularly seen as merely performing
   technical functions.  However, these protocols and standards do not
   exist outside of their technical context context, nor do they exist outside
   of their political, historical, economic, legal legal, or cultural context.
   This is best exemplified by the way in which some Internet processes
   and protocols have become part and parcel of political processes and
   public policies: one only has to look at the IANA transition, the RFC
   on pervasive monitoring
   [RFC7258] ("Pervasive Monitoring Is an Attack"), or global innovation policy
   policy, for concrete examples [Denardis15]. [DeNardis15].  According to [Abbate]: [Abbate],
   "protocols are politics by other means". means."  This statement would
   probably not garner IETF consensus, but it nonetheless confers reveals that
   protocols are based on decision making, decision-making, most often by humans.  In
   this process process, the values and ideas about the role that a particular
   technology should perform in society is are embedded into the design.  Often
   Often, these design decisions are part pure-technical, partly "purely technical" and part
   partly inspired by a certain world view of how technology should
   function that is inspired by personal,
   corporate corporate, and political
   views.  Within the community of IETF
   participants participants, there is a strong
   desire to solve technical problems and to minimize engagement with
   political processes and non-protocol related non-protocol-related political issues.

   Since the late 1990's 1990s, a burgeoning group of academics and
   practitioners researched questions surrounding the societal impact of
   protocols, and as well as the politics of protocols.  These studies vary
   in focus and scope: some focus on specific standards [Davidsonetal]
   [Musiani], [Davidson-etal]
   [Musiani]; others look into the political, legal, commercial commercial, or
   social impact of protocols [BrownMarsden] [Lessig], [Mueller] [Lessig] [Mueller]; and yet
   others look at how the engineers' personal set of values get
   translated into technology [Abbate] [CathFloridi] [Denardis15] [DeNardis15]
   [WynsbergheMoura].

   Commercial and political influences on the management of the
   Internet's infrastructure are well-documented well documented in the academic
   literature and will thus not be discussed here [Benkler]  [Brownetal]
   [Denardis15]  [Lessig]  [Mueller] here; see [Benkler],
   [Brown-etal], [DeNardis15], [Lessig], [Mueller], and [Zittrain].  It
   is sufficient to say that the IETF community consistently tries to
   push back against the standardization of surveillance and certain
   other issues that negatively influence end-users' an end user's experience of of,
   and trust in in, the Internet [Denardis14]. [DeNardis14].  The role that human rights
   play in engineering, infrastructure maintenance maintenance, and protocol design
   is much less clear.

   It is very important to understand how protocols and standards impact
   human rights.  In rights, in particular because Standard Developing
   Organizations (SDOs) SDOs are increasingly becoming
   venues where social values (like human rights) are discussed,
   although often from a technological point of view.  These SDOs are
   becoming a new focal point for discussions about values-by-design, "values by design"
   and the role of technical engineers in protecting or enabling human
   rights
   [Brownetal] [Clarketal] [Denardis14] [Brown-etal] [Clark-etal] [DeNardis14] [CathFloridi] [Lessig]
   [Rachovitsa].

   In the academic literature literature, five clear positions can be discerned, discerned in
   relation to the role of human rights in protocol design and how to
   account for these human rights in protocol development: Clark
   et al. [Clark-etal] argue that there is a need to 'design for design "for
   variation in outcome, outcome -- so that the outcome can be different in
   different places, and the tussle takes place within the design (...) (...)"
   [as] Rigid "Rigid designs will be broken; designs that permit variation
   will flex under pressure and
   survive [Clarketal].' survive."  They hold that human rights
   should not be hard-coded into protocols because of for three reasons: first, First, the
   rights in the UDHR are not absolute.  Second, technology is not the
   only tool in the tussle over human rights.  And last but not least,
   it is dangerous to make promises that can't be kept.  The open nature
   of the Internet will never, they argue, be enough to fully protect
   individuals' human rights.

   Conversely, Brown et al.  [Brownetal] [Brown-etal] state that 'some "some key, universal
   values - -- of which the UDHR is the most legitimate expression - --
   should be baked into the architecture at design time.' time."  They argue
   that design choices have offline consequences, consequences and are able to shape
   the power positions of groups or individuals in society.  As such,
   the individuals making these technical decisions have a moral
   obligation to take into account the impact of their decisions on society, and
   society and, by
   extension extension, human rights.  Brown et al recognise al. recognize that
   values and the implementation of human rights vary across the globe.
   Yet they argue that all members of the United Nations have found 'common
   "common agreement on the values proclaimed in the Universal
   Declaration of Human Rights.  In looking for the most legitimate set
   of global values to embed in the future Internet architectures, the
   UDHR has the democratic assent of a significant fraction of the
   planet's population, through their elected representatives."

   The main disagreement between these two academic positions lies
   mostly in the question on of whether (1) a particular value system
   should be embedded into the Internet's architectures or whether (2) the
   architectures need to account for a varying set of values.

   A third position that position, which is similar to that of Brown et al., is taken
   by
   [Broeders] who [Broeders], in which Broeders argues that 'we "we must find ways to
   continue guaranteeing the overall integrity and functionality of the
   public core of the Internet.' Internet."  He argues that the best way to do this
   is by declaring the backbone of the Internet - -- which includes the
   TCP/IP protocol suite, numerous standards, the Domain Name System
   (DNS), and routing protocols - -- a common public good.  This is a
   different approach than that those of [Clarketal] [Clark-etal] and [Brownetal] [Brown-etal]
   because Broeders does not suggest that social values should (or
   should not) be explicitly coded into the Internet, but rather that
   the existing infrastructure should be seen as an entity of public
   value.

   Bless and Orwat [Bless] [Bless2] represent a fourth position.  They argue
   that it is too early to make any definitive claims, claims but that there is
   a need for more careful analysis of the impact of protocol design
   choices on human rights.  They also argue that it is important to
   search for solutions that 'create "create awareness in the technical
   community about impact of design choices on social values.  And work values" and "work
   towards a methodology for co-design of technical and institutional
   systems.'
   systems."

   Berners-Lee and Halpin [BernersLeeHalpin] represent a fifth position.
   They argue that the Internet could lead to even new newer capacities, and
   these capacities may over time be viewed as new kinds of rights.  For
   example, Internet access may be viewed as a human right in and of
   itself if it is taken to be a pre-condition precondition for other rights, even if
   it could not have been predicted at the declaration
   of time that the UNHDR after UDHR was
   written (after the end of World War 2.[BernersLeeHalpin]. II).

   It is important to contextualize the technical discussion with the
   academic discussions on this issue.  The academic discussions also are
   also important to document document, as they inform the position of the
   authors of this document.  The Research Groups research group's position is that
   hard-coding human rights into protocols is complicated and changes
   with the context.  At this point point, it is difficult to say whether or
   not hard-coding human rights into protocols is wise or feasible.
   Additionally, there are many human rights, but that not all are relevant
   for ICTs. information and communications technologies (ICTs).  A partial
   catalog, with
   catalog (with references to sources, sources) of human rights related to ICTs
   can be found here in [Hill2014].  It is however is, however, important to make
   conscious and explicit design decisions that take into account the
   human rights protocol considerations guidelines developed below.
   This will contribute to the understanding of the impact that
   protocols can have on human rights, both for both developers and for users.
   In addition, it contributes to (1) the careful consideration of the
   impact that a specific protocol might have on human rights and that concrete
   (2) the dissemination of the practice of documenting protocol design
   decisions are documented in the protocol. related to human rights.

   Pursuant to the principle of constant change, since because the function
   and scope of the Internet evolves, evolve, so does the role of the IETF in
   developing standards.  Internet standards Standards are adopted based on the basis of a
   series of criteria, including high technical quality, support by
   community consensus, and their overall benefit to the Internet.  The
   latter calls for an assessment of the interests of all affected
   parties and the specifications' impact on the Internet's users.  In
   this respect, the effective exercise of the human rights of the
   Internet users is a relevant consideration that needs to be
   appreciated in the standardization process insofar as it is directly
   linked to the reliability and core values of the Internet. Internet [RFC1958]
   [RFC0226] [RFC3724]
   [RFC2775] [RFC3439] [RFC3724].

   This document details the steps taken in the research into human
   rights protocol considerations by the hrpc research group HRPC Research Group to clarify
   the relation relationship between technical concepts used in the IETF and
   human rights.  This document sets out some preliminary steps and
   considerations for engineers to take into account when developing
   standards and protocols.

5.  Methodology

   Mapping the relation relationship between human rights, protocols protocols, and
   architectures is a new research challenge, which challenge that requires a good amount
   of interdisciplinary and cross organizational cross-organizational cooperation to develop
   a consistent methodology.

   The methodological choices made in this document are based on the
   political science-based
   political-science-based method of discourse analysis and ethnographic
   research methods [Cath].  This work departs from the assumption that
   language reflects the understanding of concepts.  Or  Or, as [Jabri]
   holds, policy documents are 'social "social relations represented in texts
   where the language contained within these texts is used to construct
   meaning and representation'. representation."  This process happens in 'the social space of society' [Schroeder] society
   [Denzin] and manifests itself in institutions and organizations
   [King], exposed using the ethnographic methods of semi-structured
   interviews and participant observation.  Or  Or, in non-academic
   language, the way the language in IETF/IRTF documents describes and
   approaches the issues they are trying to address is an indicator for indication of
   the underlying social assumptions and relations relationships of the engineers
   to their engineering.  By reading and analyzing these documents, as
   well as interviewing engineers and participating in the IETF/IRTF
   working groups, it is possible to distill the relation relationship between
   human rights, protocols protocols, and the Internet's infrastructure as it
   pertains to the work of the IETF.

   The discourse analysis was operationalized using qualitative and
   quantitative means.  The first step taken by the authors and
   contributors was reading RFCs and other official IETF documents.  The
   second step was the use of a python-based Python-based analyzer, using the tool
   Big Bang,
   "Bigbang" tool, adapted by Nick Doty [Doty] [Doty], to scan for the concepts
   that were identified as important architectural principles (distilled
   on the initial reading and supplemented by the interviews and
   participant observation).  Such a quantitative method is very precise
   and speeds up the research process [Richie]. [Ritchie].  But this tool is
   unable to understand 'latent meaning' "latent meaning" [Denzin].  In order to mitigate
   these issues of automated word-frequency based approaches, word-frequency-based approaches and to get
   a sense of the 'thick meaning' "thick meaning" [Geertz] of the data, a second
   qualitative analysis of the data set was performed.  These various
   rounds of discourse analysis were used to inform the interviews and
   further data analysis.  As such such, the initial rounds of quantitative
   discourse analysis were used to inform the second rounds of
   qualitative analysis.  The results from the qualitative interviews
   were again used to feed new concepts into the quantitative discourse
   analysis.  As such such, the two methods continued to support and enrich
   each other.

   The ethnographic methods of the data collection and processing
   allowed the research group to acquire the data necessary to 'provide "provide
   a holistic understanding of research participants' views and actions' actions"
   [Denzin] that highlighted ongoing issues and case studies where
   protocols impact human rights.  The interview participants were
   selected through purposive sampling [Babbie], as the research group
   was interested in getting a wide variety of opinions on the role of
   human rights in guiding protocol development.  This sampling method
   also ensured that individuals with extensive experience working at
   the IETF in various roles were targeted.  The interviewees included
   individuals in leadership positions (Working Group (WG) chairs, Area
   Directors (ADs)), 'regular participants', "regular participants", and individuals working for
   specific entities (corporate, civil society, political, academic) and
   represented various backgrounds, nationalities nationalities, and genders.

5.1.  Data Sources

   In order to map the potential relation relationship between human rights and
   protocols, the HRPC research group Research Group gathered data from three specific
   sources:

5.1.1.  Discourse analysis Analysis of RFCs

   To start addressing the issue, a mapping exercise analyzing Internet
   infrastructure and protocols features, protocol features vis-a-vis their possible impact
   on human rights was undertaken.  Therefore, research on (1) the
   language used in current and historic RFCs and mailing list (2) information
   gathered from mailing-list discussions was undertaken to expose core
   architectural principles,
   language language, and deliberations on the human
   rights of those affected by the network.

5.1.2.  Interviews with members Members of the IETF community Community

   Over 30 interviews with the current and past members of the Internet
   Architecture Board (IAB), current and past members of the Internet
   Engineering Steering Group (IESG) and (IESG), chairs of selected working
   groups groups,
   and RFC authors were done at the IETF92 Dallas IETF 92 meeting in Dallas in
   March 2015.  To 2015 to get an insider insider's understanding of how they view the
   relationship (if any) between human rights and protocols to play protocols, and how
   this relationship plays out in their work.  Several of the
   participants opted to remain
   anonymous, if anonymous.  If you are interested in
   this data set set, please contact the
   authors. authors of this document.

5.1.3.  Participant observation Observation in Working Groups

   By participating in various working groups, in person at IETF
   meetings
   meetings, and on mailinglists, mailing lists, information was gathered about the
   IETFs IETF's
   day-to-day workings.  From workings was gathered, from which general themes,
   technical concepts, and use-cases use cases about human rights and protocols
   were extracted.  This process started at the IETF91 IETF 91 meeting in
   Honolulu and continues today.

5.2.  Data analysis strategies Analysis Strategies

   The data above was processed using three consecutive strategies:
   mapping protocols related to human rights, extracting concepts from
   these protocols, and creation of a common glossary (detailed under
   Section 2).  Before going over these strategies strategies, some elaboration on
   the process of identifying technical concepts as they relate to human
   rights needs to be given: is needed:

5.2.1.  Identifying qualities Qualities of technical concepts that relate Technical Concepts That Relate to human
        rights Human
        Rights

5.2.1.1.  Mapping protocols Protocols and standards Standards to human rights Human Rights

   By combining data from the three data sources named above, an
   extensive list of protocols and standards that potentially enable the
   Internet as a tool for freedom of expression and association was
   created.  In order to determine the enabling (or inhibiting) features
   features, we relied on direct references of such impact in the RFCs, RFCs as related to
   such impacts, as well as input from the community.  On the basis of  Based on this analysis
   analysis, a list of RFCs that describe standards and protocols that
   are potentially closely related to human rights was compiled.

5.2.1.2.  Extracting concepts Concepts from selected Selected RFCs

   Identifying

   The first step was to identify the protocols and standards that are
   related to human rights and to create a human rights enabeling an environment was the first
   step.  For that enables
   human rights.  For that, we needed to focus on specific technical
   concepts that underlie these protocols and standards.  On the basis of  Based on this
   list
   list, a number of technical concepts that appeared frequently was
   extracted, were
   extracted and used to create a second list of technical terms that,
   when combined and applied in different circumstances, create an
   enabling environment for excercising exercising human rights on the Internet.

5.2.1.3.  Building a common vocabulary Common Vocabulary of technical concepts that impact
          human rights Technical Concepts That Impact
          Human Rights

   While interviewing experts, investigating RFCs RFCs, and compiling
   technical definitions definitions, several concepts of convergence and divergence
   were identified.  To ensure that the discussion was based on a common
   understanding of terms and vocabulary, a list of definitions was
   created.  The definitions are based on the wording found in various
   IETF documents, and documents; if these the definitions were unavailable not available therein,
   definitions were taken from definitions from other Standards Developing Organizations SDOs or academic literature, as
   indicated in the vocabulary section. Section 2.

5.2.1.4.  Translating Human Rights Concepts into Technical Definitions

   The previous steps allowed for the clarification of relations relationships
   between human rights and technical concepts.  The steps taken show
   how the research process zoomed in, "zoomed in", from compiling a broad lists list of
   protocols and standards that relate to human rights to extracting the
   precise technical concepts that make up these protocols and
   standards, in order to understand the relationship between the two.
   This sub-
   section subsection presents the next step: translating human rights to
   technical concepts by matching the individuals individual components of the
   rights to the accompanying technical concepts, allowing for the
   creation of a list of technical concepts that that, when partially combined
   combined, can create an enabling environment for human rights.

5.2.1.5.  List technical terms that when partially combined can create of Technical Terms That, When Partially Combined, Can
          Create an enabling environment Enabling Environment for human rights

   On the basis of Human Rights

   Based on the prior steps steps, the following list of technical
   terms, that when terms was
   drafted.  When partially combined combined, this list can create an enabling
   environment for human rights, such a as freedom of expression and
   freedom of association, was drafted. association.

   The combination of the technical concepts that have been gathered listed in the steps above have been grouped
   according to their impact on specific
   rights rights, as they have been mentioned in the
   interviews done at IETF92 IETF 92 as well as the study of literature (see literature
   Section 4 ("Literature and discussion review Discussion Review") above).

   This analysis aims to assist protocol developers in better
   understanding the roles that specific technical concepts have with regards
   regard to their contribution to an enabeling enabling environment for people to
   excise
   exercise their human rights.

   This analysis does not claim to be a complete or exhaustive mapping
   of all possible ways in which a protocols could potentially impact
   human rights, but it presents an initial concept a mapping of initial concepts based on

5.2.3.  Map cases  Mapping Cases of protocols, implementations Protocols, Implementations, and networking paradigms
        that adversely impact human rights Networking
        Paradigms That Adversely Impact Human Rights or are enablers thereof Are Enablers

   Given the information above, the following list of cases of
   protocols, implenentations implementations, and networking paradigms that either
   adversely impact or enable human rights was formed.

   It is important to note that the assessment here is not a general
   judgment on these protocols, nor is it an exhaustive listing of all
   the potential negative or positive impacts on human rights they that these
   protocols might have.  When they these protocols were conceived, there
   were many criteria to take into account.  For instance, relying on an a
   centralized service can be bad for freedom of speech (it creates one
   more control point, where censorship could be applied) applied), but it may be
   a necessity if the endpoints are not connected and reachable
   permanently.  So, when we say "protocol X has feature Y, which may
   endanger the freedom of
   speech", speech," it does not mean that protocol X is bad and even bad,
   much less that its authors were evil.  The goal here is to show, with
   actual examples, that the design of protocols have has practical
   consequences for some human rights and that these consequences have
   to be considered in the design phase.

5.2.3.1.  IPv4

   The Internet Protocol version 4 (IPv4), also known as 'layer 3' "Layer 3" of
   the Internet, Internet and specified as with a common encapsulation and protocol
   header, is defined in [RFC0791]. [RFC791].  The evolution of Internet
   communications led to continued development in this area,
   encapsulated
   "encapsulated" in the development of version 6 (IPv6) of the protocol
   in [RFC2460].
   [RFC8200].  In spite of this updated protocol, we find that 25 23 years
   after the specification of version 6 of the protocol, IPv6 the older
   v4 IPv4 standard continues to
   account for a sizeable sizable majority of Internet
   traffic, and most traffic.  Most of the
   issues discussed here (with the big
   exception of NAT, see (Network Address Translation) Translators (NATs) are a major
   exception; see Section 5.2.3.1.2 ("Address Translation and
   Mobility")) are valid for IPv4 as well as IPv6.

   The Internet was designed as a platform for free and open
   communication, most notably encoded in the end-to-end principle, and
   that philosophy is also present in the technical implementation of
   the Internet Protocol.  [RFC3724] IP
   [RFC3724].  While the protocol was designed to exist in an
   environment where intelligence is at the end hosts, it has proven to
   provide sufficient information that a more intelligent network core
   can make policy decisions and enforce policy-based traffic shaping and shaping,
   thereby restricting the communications of end hosts.  These
   capabilities for network control and for limitations of the on freedom of
   expression by end hosts can be traced back to the IPv4 design, design of IPv4,
   helping us to understand which technical protocol decisions have led
   to harm of to this human rights. right.  A feature that can harm freedom of
   expression as well as the right to privacy through misuse of the
   Internet Protocol IP is
   the exploitation of the public visibility of the host pairs for all communications,
   communications and the corresponding ability to
   discriminate differentiate and
   block traffic as a result of that metadata.

5.2.3.1.1.  Network visibility Visibility of Source and Destination

   The IPv4 protocol header contains fixed location fields for both the
   source IP address and destination IP addresses [RFC0791]. address [RFC791].  These
   addresses identify both the host sending and the host receiving each message, and
   message; they also allow the core network to understand who is
   talking to whom, whom and to practically limit communication selectively
   between pairs of hosts.  Blocking of communication based on the pair
   of source and destination is one of the most common limitations on
   the ability for people to communicate today, [caida] today [CAIDA] and can be seen
   as a restriction of the ability for people to assemble or to
   consensually express themselves.

   Inclusion of an Internet-wide identified source in the IP header
   is not the only possible design, especially since the protocol is
   most commonly implemented over Ethernet networks exposing only
   link-local identifiers [RFC0894]. [RFC894].

   A variety of alternative designs do exist, such as the Accountable
   and Private Internet Protocol [APIP] and Hornet [Hornet] High-speed Onion Routing at
   the Network Layer (HORNET) [HORNET] as well as source routing.  The
   latter would allow for the sender to choose a
   pre-defined predefined (safe) route and
   spoofing of the source IP address, which are technically supported by the IPv4 protocol,
   IPv4, but neither are considered good practice on the Internet
   [Farrow].  While projects like [torproject] [TorProject] provide an alternative
   implementation of anonymity in connections, they have been developed
   in spite of the IPv4 protocol design.

5.2.3.1.2.  Address Translation and Mobility

   A major structural shift in the Internet which that undermined the protocol
   design of IPv4, and significantly reduced the freedom of end users to
   communicate and assemble is assemble, was the introduction of network address translation.  [RFC3022]
   translation [RFC3022].  Network address translation is a process
   whereby organizations and autonomous systems connect two networks by
   translating the IPv4 source and destination addresses between the two. them.
   This process puts the router performing the translation into in a
   privileged position, where it can decide is predetermined which subset of
   communications are worthy of translation, and whether an
   unknown request for communication will be correctly forwarded to a
   host on the other network. translated.

   This process of translation has widespread adoption despite promoting
   a process that goes against the stated end-to-end process of the
   underlying protocol [natusage]. [NATusage].  In contrast, the proposed mechanism
   to provide support for mobility and forwarding to clients which that may
   move,
   move -- encoded instead as an option in the IP protocol in [RFC5944], [RFC5944] -- has failed to
   gain traction.  In this situation situation, the compromise made in the design
   of the protocol resulted in a technology that is not coherent with
   the end-to-end principles and thus creates an extra possible hurdle
   for freedom of expression in its design, even though a viable
   alternative exists.  There is a particular problem surrounding NATs
   and VPN Virtual Private Networks (VPNs) (as well as other connections
   used for privacy purposes) purposes), as NATs sometimes cause VPNs not to work.

5.2.3.2.  DNS

   The Domain Name System (DNS) [RFC1035], [RFC1035] provides service discovery
   capabilities,
   capabilities and provides a mechanism to associate human readable human-readable
   names with services.  The DNS system is organized around a set of
   independently operated 'Root Servers' "root servers" run by organizations which that
   function in line with ICANN's policy by answering queries for which
   organizations have been delegated to manage registration under each
   Top Level
   Top-Level Domain (TLD).  The DNS is organized as a rooted tree, and
   this brings up political and social concerns over control.  Top Level
   domains  TLDs are
   maintained and determined by ICANN.  These namespaces encompass
   several classes of services.  The initial name spaces namespaces, including '.Com'
   ".com" and '.Net', ".net", provide common spaces for expression of ideas,
   though their policies are enacted through US based through US-based companies.  Other name spaces
   namespaces are delegated to specific nationalities, nationalities and may impose
   limits designed to focus speech in those forums both forums, to both (1) promote
   speech from that nationality, nationality and to (2) comply with local limits on
   expression and social norms.  Finally, the system has recently been
   expanded with additional generic and sponsored name spaces, namespaces -- for
   instance '.travel'
   instance, ".travel" and '.ninja', which ".ninja" -- that are operated by a range of
   organizations which that may independently determine their registration
   policies.  This new development has both positive and negative
   implications in terms of enabling human rights.  Some individuals
   argue that it undermines the right to freedom of expression because
   some of these new gtlds generic TLDs have restricted policies on
   registration and particular rules on hate speech content.  Others
   argue that precisely these properties are positive because they
   enable certain (mostly minority) communities to build safer spaces
   for association, thereby enabling their right to freedom of
   association.  An often mentioned often-mentioned example is an application like
   .gay [CoE].

   As discussed in [RFC7626], DNS has significant privacy issues per [RFC7626]. issues.  Most
   notable is the lack of encryption to limit the visibility of requests
   for domain resolution from intermediary parties, and a limited
   deployment of DNSSEC to provide authentication, allowing the client
   to know that they received a correct, "authoritative", "authoritative" answer to a
   query.  In response to the privacy issues, the IETF DNS PRIVate Private
   Exchange (DPRIVE) Working Group is developing mechanisms to provide
   confidentiality to DNS transactions, to address concerns surrounding
   pervasive monitoring [RFC7258].

   Authentication through DNSSEC creates a validation path for records.
   This authentication protects against forged or manipulated DNS data.
   As such such, DNSSEC protects the directory look-up lookups and makes hijacking of it harder to
   hijack a session harder. session.  This is important because currently interference with the
   operation of the DNS is currently becoming one of the central
   mechanisms used to block access to websites.  This interference
   limits both the freedom of expression of the publisher to offer their
   content,
   content and the freedom of assembly for clients to congregate in a
   shared virtual space.  Even though DNSSEC doesn't prevent censorship,
   it makes it clear that the returned information is not the
   information that was requested, which requested; this contributes to the right to
   security and increases trust in the network.  It is however is, however,
   important to note that DNSSEC is currently not widely supported or
   deployed by domain name registrars, making it difficult to
   authenticate and use correctly.

5.2.3.2.1.  Removal of records Records

   There have been a number of cases where the records for a domain are
   removed from the name system due to political events.  Examples of
   this removal includes include the 'seizure' "seizure" of wikileaks [bbc-wikileaks] [BBC-wikileaks] and
   the names of illegally operating gambling operations by the United
   States Immigrations Immigration and Customs Enforcement unit (ICE). (ICE) unit.  In the first
   case, a US court ordered the registrar to take down the domain.  In
   the second, ICE compelled the US-based registry in charge of the .com
   TLD to hand ownership of those domains over to the US government.
   The same technique has been used in Libya to remove sites in
   violation of "our Country's Law and Morality (which) do not allow any
   kind of pornography or its promotion."  [techyum]

   At a protocol level, there is no technical auditing for name
   ownership, as in alternate systems like [namecoin]. Namecoin [Namecoin].  As a
   result, there is no ability for users to differentiate seizure from
   the legitimate transfer of name ownership, which is purely a policy
   decision of made by registrars.  While DNSSEC addresses the network
   distortion events described below, it does not tackle this problem.

   (While mentioning

   (Although we mention alternative techniques, this is not a comparison
   of DNS with Namecoin: the latter has its own problems and
   limitations.  The idea here is to show that there are several
   possible choices, and they have consequences for human rights.)

5.2.3.2.2.  Distortion of records Records

   The most common mechanism by which the DNS system is abused to limit freedom
   of expression is through manipulation of protocol messages by the
   network.  One form occurs at an organizational level, where client
   computers are instructed to use a local DNS resolver controlled by
   the organization.  The DNS resolver will then selectively distort
   responses rather than request the authoritative lookup from the
   upstream system.  The second form occurs through the use of deep packet inspection, Deep
   Packet Inspection (DPI), where all DNS protocol messages are
   inspected by the network, network and objectionable content is distorted, as
   can be observed in Chinese network. networks.

   A notable instance of distortion occurred in Greece [ververis], [Ververis], where
   a study found evidence of both of deep packet inspection (1) DPI to distort DNS replies, replies and
   (2) more excessive blocking of content than was legally required or
   requested (also known as overblocking).  ISPs "overblocking").  Internet Service Providers
   (ISPs), obeying a governmental order, prevented clients from
   resolving the names of domains which they were
   instructed to do through a governmental order, domains, thereby prompting this particular
   blocking of systems there.

   At a protocol level, the effectiveness of these attacks is made
   possible by a lack of authentication in the DNS protocol.  DNSSEC
   provides the ability to determine the authenticity of responses when
   used, but it is not regularly checked by resolvers.  DNSSEC is not
   effective when the local resolver for a network is complicit in the
   distortion,
   distortion -- for instance instance, when the resolver assigned for use by an
   ISP is the source of injection.  Selective distortion of records is
   also
   been made possible by the predictable structure of DNS messages,
   which make makes it computationally easy for a network device to watch all
   passing messages even at high speeds, and the lack of encryption,
   which allows the network to distort only an objectionable subset of
   protocol messages.  Specific distortion mechanisms are discussed
   further in [hall]. [Hall].

   Users can switch to another resolver, resolver -- for instance instance, a public one.
   resolver.  The distorter can then try to block or hijack the
   connection to this resolver.  This may start an arm's arms race, with the
   user switching to secured connections to this alternative resolver ([RFC7858]),
   [RFC7858] and the
   disruptor distorter then trying to find more sophisticated
   ways to block or
   hijack. hijack the connection.  In some cases, this search
   for an alternative, non-
   disrupting resolver, non-disrupting resolver may lead to more centralisation,
   centralization because many people
   going are switching to a few big
   commercial public resolvers.

5.2.3.2.3.  Injection of records Records

   Responding incorrectly to requests for name lookups is the most
   common mechanism that in-network devices use to limit the ability of
   end users to discover services.  A deviation, which deviation that accomplishes a
   similar objective and may be seen as different from a freedom "freedom of
   expression perspective,
   expression" perspective is the injection of incorrect responses to
   queries.  The most prominent example of this behavior occurs in
   China, where requests for lookups of sites deemed inappropriate will
   trigger the network to respond with return a false response, causing the client to
   ignore the real response when it subsequently arrives.
   [greatfirewall] arrives
   [greatfirewall].  Unlike the other forms of discussion mentioned network paradigms discussed above,
   injection does not stifle the ability of a server to announce it's
   name, its
   name; it instead provides another voice which that answers sooner.  This is
   effective because without DNSSEC, the protocol will respond to
   whichever answer is received first, without listening for subsequent
   answers.

5.2.3.3.  HTTP

   The Hypertext Transfer Protocol (HTTP), described in its (HTTP) version 1.1
   in RFC 7230 to 7237, [RFC7230]
   [RFC7231] [RFC7232] [RFC7233] [RFC7234] [RFC7235] [RFC7236] [RFC7237]
   is a request-response application protocol developed throughout the 1990s, and
   1990s.  HTTP factually contributed to the exponential growth of the
   Internet and the inter-connection interconnection of populations around the world.
   Its simple design strongly contributed to the fact that HTTP has
   become the foundation of most modern Internet platforms and
   communication systems, from websites, websites to chat
   systems, systems and computer-to-computer computer-to-
   computer applications.  In its manifestation
   with in the World Wide Web,
   HTTP radically revolutionized the course of technological development
   and the ways people interact with online content and with each other.

   However, HTTP is also a fundamentally insecure protocol, protocol that doesn't
   natively provide encryption properties.  While the definition of the
   Secure Sockets Layer (SSL) [RFC6101], and later of Transport Layer
   Security (TLS)[RFC5246], (TLS) [RFC5246], also happened during the 1990s, the fact
   that HTTP doesn't mandate the use of such encryption layers to by
   developers and service providers, providers was one of the reasons for a very
   late adoption of encryption.  Only in the middle of the 2000s did we
   observe big Internet service providers, ISPs, such as Google, starting to provide encrypted
   access to their web services.

   The lack of sensitivity and understanding of the critical importance
   of securing web traffic incentivized certain (offensive) actors to
   develop, deploy deploy, and utilize at large interception systems at large and to
   later launch active injection attacks, in order to swipe large
   amounts of data, data and compromise Internet-enabled devices.  The
   commercial availability of systems and tools to perform these types
   of attacks also led to a number of human rights abuses that have been
   discovered and reported over the years.

   Generally

   Generally, we can identify in Traffic Interception traffic interception (Section 5.2.3.3.1)
   and Traffic
   Manipulation traffic manipulation (Section 5.2.3.3.2) as the two most
   problematic attacks that can be performed against applications
   employing a clear-text cleartext HTTP transport layer.  That being said, the
   IETF is taking steady steps to move to the encrypted version of HTTP, HTTPSecure
   HTTP Secure (HTTPS).

   While this is commendable, we must not lose track of the fact that
   different protocols, implementations, configurations configurations, and networking
   paradigms can intersect such that they (can be used to) adversely
   impact human rights.  For instance, to facilitate surveillance,
   certain countries will throttle HTTPS connections connections, forcing users to
   switch to the (unthrottled) HTTP
   to facilitate surveillance [Aryanetall]. [Aryan-etal].

5.2.3.3.1.  Traffic Interception

   While we are seeing an increasing trend in the last couple of years
   to employ SSL/TLS as a secure traffic layer for HTTP-based
   applications, we are still far from seeing an a ubiquitous use of
   encryption on the World Wide Web.  It is important to consider that
   the adoption of SSL/TLS is also a relatively recent phenomena.
   E-mail phenomenon.

   Email providers such as riseup.net were the first ones to enable SSL by
   default.  Google introduced did not introduce an option for its GMail Gmail users to
   navigate with SSL only in until 2008 [Rideout], [Rideout] and turned TLS on by default later
   later, in 2010 [Schillace].  It took an increasing amount of security
   breaches and revelations on global surveillance from Edward Snowden to have
   before other mail service providers to follow followed suit.  For example,
   Yahoo enabled did not enable SSL/TLS by default on its webmail services
   only towards the end of 2013 until
   early 2014 [Peterson].

   TLS itself has been subject to many attacks and bugs which bugs; this situation
   can be attributed to some fundamental design weaknesses weaknesses, such as lack
   of a state machine, which machine (which opens a vulnerability for a Triple Handshake
   Attack, triple handshake
   attacks) and flaws caused by early U.S. US government restrictions on
   cryptography, leading to cipher-suite downgrade attacks (Logjam
   attack).
   attacks).  These vulnerabilities are being corrected in TLS1.3. TLS 1.3

   remove the "S" "s" in any links to HTTPS URIs from a web-page web page transferred
   in cleartext over HTTP, HTTP -- an attack called "SSL Stripping"
   [sslstrip].  Thus, for high security high-security use of HTTPS HTTPS, IETF standards
   such as HSTS HTTP Strict Transport Security (HSTS) [RFC6797], certificate
   pinning [RFC7469] [RFC7469], and/or DANE DNS-Based Authentication of Named Entities
   (DANE) [RFC6698] should be used.

   As we learned through the Snowden's revelations, intelligence agencies
   have been intercepting and collecting unencrypted traffic at large
   for many years.  There are documented examples of such mass
   surveillance
   mass-surveillance programs with GCHQ's TEMPORA the Government Communications
   Headquarters's (GCHQ's) Tempora [WP-Tempora] and NSA's
   XKEYSCORE the National
   Security Agency's (NSA's) XKeyscore [Greenwald].  Through these programs NSA/GCHQ
   programs, the NSA and the GCHQ have been able to swipe large amounts
   of data data, including email and instant messaging communications which that
   have been transported by the
   respective providers in the clear for years, years by providers
   unsuspecting of the pervasiveness and scale of governments' efforts
   and investment into in global mass surveillance mass-surveillance capabilities.

   However, similar mass interception of unencrypted HTTP communications
   is also often employed at a nation-level the national level by some democratic countries
   countries, by exercising control over state-owned Internet Service Providers
   (ISP) ISPs and through
   the use of commercially available monitoring, collection, and
   censorship equipment.  Over the last few years years, a lot of information
   has come to public attention on the role and scale of a surveillance
   industry dedicated to develop interception gear of developing different types, types of interception
   gear, making use of known and unknown weaknesses in existing
   protocols [RFC7258].  We have several records of such equipment being
   sold and utilized by some regimes in order to monitor entire segments
   of population a population, especially at times of social and political
   distress, uncovering massive human rights abuses.  For example, in 2013
   2013, the group Telecomix revealed that the Syrian regime was making
   use of BlueCoat Blue Coat products in order to intercept clear-text cleartext traffic as
   well as to enforce censorship of unwanted content [RSF].
   Similarly  Similarly,
   in 2012 2011, it was found that the French technology firm Amesys provided
   the
   Gaddafi's Gadhafi government with equipment able to intercept emails,
   Facebook traffic, and chat messages at a country country-wide level [WSJ].
   The use of such systems, especially in the context of the Arab Spring
   and of civil uprisings against the dictatorships, has caused serious
   concerns of regarding significant human rights abuses in Libya.

5.2.3.3.2.  Traffic Manipulation

   The lack of a secure transport layer under HTTP connections not only
   exposes the users to interception of the content of their
   communications, communications
   but is more and more commonly abused as a vehicle for actively
   compromising computers and mobile devices.  If an HTTP session
   travels in the clear over the network, any node positioned at any
   point in the network is able to perform man-in-the-middle attacks
   and attacks;
   the node can observe, manipulate, and hijack the session and can
   modify the content of the communication in order to trigger
   unexpected behavior by the application generating the traffic.  For
   example, in the case of a browser browser, the attacker would be able to
   inject malicious code in order to exploit vulnerabilities in the
   browser or any of its plugins.  Similarly, the attacker would be able
   to intercept, add
   malware, malware to, and repackage binary software updates
   that are very commonly downloaded in the clear by applications such
   as word processors and media players.  If the HTTP session would be were
   encrypted, the tampering of the content would not be possible, and
   these network injection attacks would not be successful.

   While traffic manipulation attacks have been long been known, documented,
   and prototyped prototyped, especially in the context of WiFi Wi-Fi and LAN networks,
   in the last few years we have observed an increasing investment into in
   the production and sale of network injection equipment that is both available
   commercially as well as available and deployed at scale by intelligence
   agencies.

   For example, we learned from some of the documents provided by Edward
   Snowden to the press, press that the NSA has constructed a global network
   injection infrastructure, called QUANTUM, "QUANTUM", able to leverage mass
   surveillance in order to identify targets of interests interest and
   subsequently task man-on-the-side attacks to ultimately compromise a
   selected device.  Among other attacks, the NSA makes use of an attack
   called QUANTUMINSERT [Haagsma] "QUANTUMINSERT" [Haagsma], which intercepts and hijacks an
   unencrypted HTTP communication and forces the requesting browser to
   redirect to a host controlled by the NSA instead of the intended
   website.  Normally, the new destination would be an exploitation
   service, referred to in Snowden documents as FOXACID, "FOXACID", which would
   attempt at
   executing to execute malicious code in the context of the target's
   browser.  The Guardian reported in 2013 that the NSA has has, for example
   example, been using these techniques to target users of the popular
   anonymity service Tor [Schneier].  The German NDR Norddeutscher Rundfunk
   (NDR) reported in 2014 that the NSA has also been using its mass surveillance
   mass-surveillance capabilities to identify Tor users at large
   [Appelbaum].

   Recently

   Recently, similar capabilities of used by Chinese authorities have been
   reported as well in what has been informally called the "Great
   Cannon" [Marcak], which raised numerous concerns on the potential
   curb on human rights and freedom of speech due to the increasing increasingly
   tighter control of Chinese Internet communications and access to
   information.

   Network injection attacks are also made widely available to state
   actors around the world through the commercialization of similar,
   smaller scale
   smaller-scale equipment that can be easily acquired and deployed at a
   country-wide level.  Certain companies are known to have network
   injection gear within their products portfolio [Marquis-Boire].  The
   technology devised and produced by some of them to perform network
   traffic manipulation attacks on HTTP communications is even the
   subject of a patent application in the United States [Googlepatent].
   Access to offensive technologies available on the commercial lawful
   interception market has led to human rights abuses and illegitimate
   surveillance of journalists, human rights defenders, and political
   activists in many countries around the world [Collins].  While
   network injection attacks haven't been the subject of much attention,
   they do enable even unskilled attackers to perform silent and very
   resilient compromises, and unencrypted HTTP remains one of the main
   vehicles.

   There is a new version of HTTP, called HTTP/2, which was published as
   [RFC7540] and "HTTP/2" [RFC7540], which aimed aims
   to be largely backwards compatible but while also
   offer offering new option options
   such as data compression of HTTP headers and headers, pipelining of request requests, and
   multiplexing multiple requests over a single TCP connection.  In
   addition to decreasing latency to improve
   page loading speeds page-loading speeds, it
   also facilitates more efficient use of connectivity in low-bandwith low-bandwidth
   environments, which is an enabler for in turn enables freedom of expression, expression; the right
   to assembly, assembly; the right to political
   participation participation; and the right to
   participate in cultural life, art arts, and science.  [RFC7540] does not
   mandate Transport Layer Security TLS or any other form of encryption, also nor does not it support
   opportunistic
   encryption, eventhough that encryption even though opportunistic encryption is now
   addressed in [RFC8164].

5.2.3.4.  XMPP

   The Extensible Messaging and Presence Protocol (XMPP), specified in
   [RFC6120], provides a standard for interactive chat messaging, messaging and has
   evolved to encompass interoperable text, voice, and video chat.  The
   protocol is structured as a federated network of servers, similar to
   email, where users register with a local server which that acts one on their
   behalf to cache and relay messages.  This protocol design has many
   advantages, allowing servers to shield clients from denial of service
   and other forms of retribution for their expression, and expression; it is also
   designed to avoid central entities which that could control the ability to
   communicate or assemble using the protocol.

   None-the-less,

   Nonetheless, there are plenty of aspects of the protocol design of
   XMPP which that shape the ability for users to communicate freely, freely and to
   assembly through
   assemble via the protocol.

5.2.3.4.1.  User Identification

   The XMPP specification [RFC6120] dictates that clients are identified
   with a resource (node@domain/home [1] (<node@domain/home> / node@domain/work [2]) <node@domain/work>) to
   distinguish the conversations to specific devices.  While the
   protocol does not specify that the resource must be exposed by the
   client's server to remote users, in practice this has become the
   default behavior.  In doing so, users can be tracked by remote
   friends and their servers, who are able to monitor the presence of
   not just of the user, user but of each individual device the user logs in
   with.  This has proven to be misleading to many users [pidgin], [Pidgin], since
   many clients only expose
   user level user-level rather than device level device-level
   presence.  Likewise, user invisibility so that communication can
   occur while users don't notify all buddies and other servers of their
   availability is not part of the formal protocol, protocol and has only been
   added as an extension within the XML stream rather than enforced by
   the protocol.

5.2.3.4.2.  Surveillance of Communication

   The

   XMPP protocol specifies the standard by which communication of communications channels may be
   encrypted, but it does not provide visibility to clients of regarding
   whether their communications are encrypted on each link.  In
   particular, even when both clients ensure that they have an encrypted
   connection to their XMPP server to ensure that their local network is
   unable to read or disrupt the messages they send, the protocol does
   not provide visibility into the encryption status between the two
   servers.  As such, clients may be subject to selective disruption of
   communications by an intermediate network
   which that disrupts
   communications based on keywords found through Deep
   Packet Inspection. DPI.  While many
   operators have commited committed to only establishing encrypted links from
   their servers in recognition of this vulnerability, it remains
   impossible for users to audit this
   behavior behavior, and encrypted
   connections are not required by the protocol itself [xmppmanifesto]. [XMPP-Manifesto].

   In particular, section Section 13.14 of the protocol XMPP specification [RFC6120]
   explicitly acknowledges the existence of a downgrade attack where an
   adversary controlling an intermediate network can force the inter
   domain
   inter-domain federation between servers to revert to a non-encrypted
   protocol were where selective messages can then be disrupted.

5.2.3.4.3.  Group Chat Limitations

   Group chat in the XMPP protocol is defined as an extension within the XML
   specification of the XMPP protocol (https://xmpp.org/extensions/
   xep-0045.html). (https://xmpp.org/extensions/xep-0045.html).
   However, it is not encoded or required at a protocol
   level, level and is not
   uniformly implemented by clients.

   The design of multi-user chat in the XMPP protocol suffers from extending a
   protocol that was not designed with assembly of many users in mind.
   In particular, in the federated protocol provided by XMPP, multi-user
   communities are implemented with a distinguished
   'owner', "owner" who is
   granted control over the participants and structure of the
   conversation.

   Multi-user chat rooms are identified by a name specified on a
   specific server, so that while the overall protocol may be federated,
   the ability for users to assemble in a given community is moderated
   by a single server.  That server may block the room and prevent
   assembly unilaterally, even between two users users, neither of whom trust
   or use that server directly.

5.2.3.5.  Peer to Peer  Peer-to-Peer

   Peer-to-Peer (P2P) is a distributed network architecture [RFC5694] in
   which all the participant nodes can be responsible for the storage
   and dissemination of information from any other node (defined in (see [RFC7574],
   an IETF standard that used discusses a P2P architecture). architecture called the
   "Peer-to-Peer Streaming Peer Protocol" (PPSPP)).  A P2P network is a
   logical overlay that lives on top of the physical
   network, network and allows
   nodes (or "peers") participating to in it to establish contact and
   exchange information directly from one to with each other.  The implementation of
   a P2P network may very vary widely: it may be structured or unstructured,
   and it may implement stronger or weaker cryptographic and anonymity
   properties.  While its most common application has traditionally been
   file-sharing (and other types of content delivery systems), P2P is a
   popular architecture for networks and applications that require (or
   encourage) decentralization.  A
   prime example is Bitcoin (and similar cryptocurrencies), as well as  Prime examples include Bitcoin and
   other proprietary multimedia applications.

   In a time of heavily centralized online services, peer-to-peer P2P is regularly
   described as an alternative, more democratic, and resistant option
   that displaces structures of control over data and communications and
   delegates all peers equally to be equally responsible for the functioning,
   integrity, and security of the data.  While in principle peer-to-peer P2P remains imporant
   important to the design and development of future content
   distribution, messaging, and publishing systems, it poses numerous
   security and privacy challenges which that are mostly delegated to
   individual developers to recognize, analyze, and solve in each
   implementation of a given P2P network.

5.2.3.5.1.  Network Poisoning

   Since content, and in some occasions sometimes peer lists, are safeguarded and
   distributed by its their members, P2P networks are prone to what are
   generally defined as "poisoning attacks".  Poisoning attacks might be
   aimed directly at the data that is being distributed, for example example,
   (1) by intentionally corrupting it, or the data, (2) at the index tables
   used to instruct the peers where to fetch the data, or (3) at routing
   tables, with the an attempt of providing to provide connecting peers with lists of
   rogue or non-
   existing nonexistent peers, with the intention to effectively cause a Denial
   denial of
   Service service on the network.

5.2.3.5.2.  Throttling

   Peer-to-Peer

   P2P traffic (and BitTorrent in particular) represents a significant
   percentage of global Internet traffic [Sandvine] [Sandvine], and it has become
   increasingly popular for Internet Service Providers ISPs to perform throttling of customers customers'
   lines in order to limit bandwidth usage [torrentfreak1] and sometimes and,
   sometimes, probably as an effect of the ongoing conflict between
   copyright holders and file-sharing communities [wikileaks].  Such
   throttling undermines the end-to-end principle.

   Throttling the peer-to-peer P2P traffic makes some uses of P2P networks
   ineffective and it
   ineffective; this throttling might be coupled with stricter
   inspection of users' Internet traffic through Deep Packet Inspection techniques
   which might pose DPI techniques,
   possibly posing additional security and privacy risks.

5.2.3.5.3.  Tracking and Identification

   One of the fundamental and most problematic issues with traditional
   peer-to-peer
   P2P networks is a complete lack of anonymization of its their users.  For
   example, in the case of BitTorrent, all peers' IP addresses are
   openly available to the other peers.  This has lead led to
   an ever-increasing
   tracking of peer-to-peer P2P and file-sharing users [ars].  As the geographical
   location of the user is directly exposed,
   and so as could also be his
   identity, the user might become a target of additional harassment and attacks, being
   attacks of a physical or legal nature.  For example, it is known that
   in Germany law firms have made extensive use of peer-to-peer P2P and file-sharing
   tracking systems in order to identify downloaders and initiate legal
   actions looking for compensations [torrentfreak2].

   It is worth noting that there are some varieties of P2P networks that
   implement cryptographic practices and that introduce anonymization of
   its
   their users.  Such implementations may be proved to be successful in
   resisting censorship of content, content and tracking of the network peers.  A primary
   prime example is FreeNet Freenet [freenet1], a free software application that
   is (1) designed to make it significantly increase the difficulty of more difficult to identify
   users and content identification, and (2) dedicated to foster fostering freedom of speech
   online [freenet2].

5.2.3.5.4.  Sybil Attacks

   In open-membership P2P networks, a single attacker can pretend to be
   many participants, typically by creating multiple fake identities of
   whatever kind the P2P network uses [Douceur].  Attackers can use
   Sybil attacks to bias choices that the P2P network makes collectively
   toward
   to the attacker's advantage, e.g., by making it more likely that a
   particular data item (or some threshold of the replicas or shares of
   a data item) are is assigned to attacker-controlled participants.  If the
   P2P network implements any voting, moderation, or peer review-
   like peer-review-like
   functionality, Sybil attacks may be used to "stuff the ballots"
   toward to
   benefit the attacker's benefit. attacker.  Companies and governments can use Sybil
   attacks on discussion-oriented P2P systems for "astroturfing" or
   creating the appearance of mass grassroots support for some position
   where in reality there is none in reality. none.  It is important to know that there
   are no known complete, environmentally sustainable, and fully
   distributed solutions to Sybil attacks, and routing via
   'friends' "friends"
   allows users to be de-anonymized via their social graph.  It is
   important to note that Sybil attacks in this context (e.f. (e.g.,
   astroturfing) are relevant to more than P2P protocols.  And protocols; they are also
   common on web based web-based systems, and they are exploited by governments
   and commercial entitities. entities.

   Encrypted P2P and Anonymous anonymous P2P networks have already emerged and provided emerged.  They
   provide viable platforms for sharing material [tribler], publish [Tribler], publishing
   content anonymously, and communicate communicating securely [bitmessage]. [Bitmessage].  These
   platforms are not perfect, and more research needs to be done.  If
   adopted at large, well-designed and resistant P2P networks might
   represent a critical component of a future secure and distributed
   Internet, enabling freedom of speech and freedom of information
   at scale.

5.2.3.6.  Virtual Private Network

   The Virtual Private Networks (VPN) that are being

   The VPNs discussed here are point-to-point connections that enables enable
   two computers to communicate over an encrypted tunnel.  There are
   multiple implementations and protocols used in the deployment of
   VPNs, and they generally diversify by encryption protocol or
   particular requirements, most commonly in proprietary and enterprise
   solutions.  VPNs are used commonly either used to (1) enable some devices to
   communicate through peculiar network configurations, or in order to (2) use some
   privacy and security properties in order to protect the traffic
   generated by the end user; user, or both.  VPNs have also become a very
   popular technology among human rights defenders, dissidents, and
   journalists worldwide to avoid local monitoring and eventually also
   to circumvent censorship.  Among human rights defenders  VPNs are often debated among human rights
   defenders as a potential alternative to Tor or other anonymous
   networks.  Such
   comparison is comparisons are misleading, as some of the privacy
   and security properties of VPNs are often misunderstood by less
   tech-savvy users,
   which users and could ultimately lead to unintended problems.

   As VPNs have increased in popularity, commercial VPN providers have
   started growing in business as businesses and are very commonly picked by human
   rights defenders and people at risk, as they are normally provided
   with an easy-to-use service and sometimes and, sometimes, even custom applications
   to establish the VPN tunnel.  Not being able to control the
   configuration of the network, and even less so let alone the security of the
   application, assessing the general privacy and security state of
   common VPNs is very hard.  Often such  Such services have often been discovered
   to be leaking information, and their custom applications have been
   found to be flawed.  While Tor and similar networks receive a lot of
   scrutiny from the public and the academic community, commercial or non-
   commercial VPN networks
   non-commercial VPNs are way far less analyzed and understood [Insinuator] [Alshalanetal] ,
   [Alshalan-etal], and it might be valuable to establish some standards
   to guarantee a minimal level of privacy and security to those who
   need them the most.

5.2.3.6.1.  No anonymity Anonymity against VPN provider Providers

   One of the common misconceptions among users of VPNs is the level of
   anonymity VPN that VPNs can provide.  This sense of anonymity can be
   betrayed by a number of attacks or misconfigurations of the VPN
   provider.  It is important to remember that, in contrast to Tor and
   similar systems, VPN was VPNs were not designed to provide anonymity
   properties.  From a technical point of view, the a VPN might leak
   identifiable
   information, information or might be the subject of correlation
   attacks that could expose the originating address of the a connecting
   user.  Most importantly, it is vital to understand that commercial
   and non-
   commercial non-commercial VPN providers are bound by the law of the
   jurisdiction in which they reside in or in which their infrastructure is
   located, and they might be legally forced to turn over data of
   specific users if legal investigations or intelligence requirements
   dictate so.  In such cases, if the VPN providers retain logs, it is
   possible that the a user's information of the user is could be provided to the user's
   adversary and leads lead to his or her identification.

5.2.3.6.2.  Logging

   With VPN being

   Because VPNs are point-to-point connections, the service providers
   are in fact able to observe the original location of the connecting users
   users, and they are able to track at what time they started their
   session
   and eventually and, eventually, also to which destinations they're trying to connect
   to.
   connect.  If the VPN providers retain logs for a long enough, enough time,
   they might be forced to turn over the relevant data or they might be
   otherwise compromised, leading to the same data getting exposed.  A
   clear log
   retaining log-retention policy could be enforced, but considerig considering that
   countries enforce different levels of data retention data-retention policies, VPN
   providers should at least be transparent on regarding what information do
   they store and for how long it is being kept.

5.2.3.6.3.  3rd Party  Third-Party Hosting

   VPN providers very commonly rely on 3rd third parties to provision the
   infrastructure that is later going to be used to run VPN endpoints.
   For example, they might rely on external dedicated server hosting
   providers, providers
   or on uplink providers.  In those cases, even if the VPN provider
   itself isn't retaining any significant logs, the information on the
   connecting users might be retained by those 3rd third parties instead,
   introducing an additional collection point for the adversary.

5.2.3.6.4.  IPv6 Leakage

   Some studies proved that several commercial VPN providers and
   applications suffer of from critical leakage of information through IPv6
   due to improper support and configuration [PETS2015VPN].  This is
   generally caused by a lack of proper configuration of the client's
   IPv6 routing tables.  Considering that most popular browsers and
   similar applications have been supporting IPv6 by default, if the
   host is provided with a functional IPv6 configuration, the traffic
   that is generated might be leaked if the VPN application isn't
   designed to manipulate such traffic properly.

5.2.3.6.5.  DNS Leakage

   Similarly, VPN services that aren't handling DNS requests and are not aren't
   running DNS servers of their own, own might be prone to DNS leaking which that
   might not only expose sensitive information on the activity of the
   user, a user
   but could also potentially lead to DNS hijacking attacks and
   following
   subsequent compromises.

5.2.3.6.6.  Traffic Correlation

   Some implementations of VPN implementations appear to be particularly vulnerable to
   identification and collection of key exchanges which, that, some Snowden
   documents revealed, are systematically collected and stored for
   future reference.  The ability of an adversary to monitor network
   connections at many different points over the Internet, Internet can allow them
   to perform traffic correlation attacks and identify the origin of
   certain VPN traffic by cross referencing cross-referencing the connection time of the
   user to the endpoint and the connection time of the endpoint to the
   final destination.  These types of attacks, although very expensive
   and normally only performed by very resourceful adversaries, have
   been documented [spiegel] [SPIEGEL] to be already in practice practice, and they could
   completely nullify the use of a VPN and ultimately expose the
   activity and the identity of a user at risk.

5.2.3.7.  HTTP Status Code 451

   Every

   "Every Internet user has run into the '404 Not Found' Hypertext
   Transfer Protocol (HTTP) status code when trying, and failing, to
   access a particular website website" [Cath].  It is a response status that
   the server sends to the browser, browser when the server cannot locate the
   URL.
   '403 Forbidden' "403 Forbidden" is another example of this class of code signals
   that gives users information about what is going on.  In the '403' case "403"
   case, the server can be reached, reached but is blocking the request because
   the user is trying to access content forbidden to them.  This them, typically
   because some content is only for identified users, based on a
   payment, payment
   or on a special status in the organisation. 403 is most organization.  Most of the time time, 403 is
   sent by the origin server, not by an intermediary.  If a firewall
   prevents a government employee to access from accessing pornography on a
   work-computer, work
   computer, it does not use 403.

   As surveillance and censorship of the Internet is are becoming more
   commonplace, voices were raised at the IETF to introduce a new status
   code that indicates when something is not available for 'legal
   reasons' "legal
   reasons" (like censorship):

   The 451 status code would allow server operators to operate with
   greater transparency in circumstances where issues of law or public
   policy affect their operation.  This transparency may be beneficial
   both
   to both (1) these operators and to end-users (2) end users [RFC7725].

   The status code is named '451', a "451" in reference to both Bradbury's famous
   novel on censorship, "Fahrenheit 451" and the to 451 degrees Fahrenheit (the temperature (in Fahrenheit)
   at which
   bookpaper autoignites. some claim book paper autoignites).

   During the IETF92 IETF 92 meeting in Dallas, there was discussion about the
   usefulness of '451'. 451.  The main tension revolved around the lack of an
   apparent machine-readable technical use of the information.  The
   extent to which '451' 451 is just 'political theatre' "political theatre" or whether it has a
   concrete technical use was heatedly debated.  Some argued that 'the "the
   451 status code is just a status code with a response body' body"; others
   said it was problematic because 'it "it brings law into the picture'.
   Again picture."
   Still others argued that it would be useful for individuals, individuals or for
   organizations like the 'Chilling Effects' project, "Chilling Effects" project that are crawling
   the web Web to get an indication of censorship (IETF discussion on '451' - 451 --
   author's field notes notes, March 2015).  There was no outright objection
   during the Dallas meeting against moving forward on status code
   '451', 451,
   and on December 18, 2015 2015, the Internet Engineering Steering
   Group IESG approved publication of 'An "An HTTP Status Code to
   Report Legal
   Obstacles'.  It Obstacles" (now [RFC7725]) for publication.  HTTP status
   code 451 is now an IETF approved IETF-approved HTTP status code to signal that signals when
   resource access is denied as a consequence of legal demands
   [RFC7725]. demands.

   What is interesting about this particular case is that not only
   technical arguments but also the status code's outright potential
   political use for civil society played a substantial role in shaping
   the discussion, discussion and the decision to move forward with this technology.

   It is nonetheless important to note that HTTP status code 451 is not
   a solution to detect all occasions of censorship.  A large swath of
   Internet filtering occurs in the network, at a lower level than HTTP,
   rather than at the server itself.  For these forms of censorship censorship, 451
   plays a limited role, as typical censoring intermediaries won't
   generate it.  Besides technical reasons, such filtering regimes are
   unlikely to voluntarily inject a 451 status code.  The use of 451 is
   most likely to apply in the case of cooperative, legal versions of
   content removal resulting from requests to providers.  One can think
   of content that is removed or blocked for legal reasons, like
   copyright infringement, gambling laws, child abuse, et cetera. etc.  Large
   Internet companies and search engines are constantly asked to censor
   content in various jurisdictions.  451 allows this to be easily
   discovered,
   discovered -- for instance instance, by initiatives like the Lumen Database.

   Overall, the strength of 451 lies in its ability to provide
   transparency by giving the reason for blocking, blocking and giving the end-
   end user the ability to file a complaint.  It allows organizations to
   easily measure censorship in an automated way, way and prompts the user to
   access the content via another path (e.g.  TOR, (e.g., Tor, VPNs) when (s)he
   encounters the 451 status code.

   Status code 451 impact impacts human rights by making censorship more
   transparent and measurable.  The status code  It increases transparency
   both by signaling
   the existence of censorship (instead of a much more
   broad broader HTTP error
   message like such as HTTP status code 404) as well as providing details of
   the legal restriction, which legal authority is imposing it, and to
   what class of resources it applies to. applies.  This empowers the user to seek
   redress.

5.2.3.8.  DDoS attacks Attacks

   Many individuals, not excluding including IETF engineers, have argued that DDoS
   attacks are fundamentally against freedom of expression.  Technically
   Technically, DDoS attacks are when attacks where one host or multiple host
   hosts overload the bandwidth or resources of another host by flooding
   it with traffic or making
   resource intensive resource-intensive requests, causing it to
   temporarily stop being available to users.  One can roughly
   differentiate three types of DDoS attacks: Volume Based Attacked (This attack aims

   1.  volume-based attacks (which aim to make the host unreachable by
       using up all it's bandwith, often used its bandwidth; often-used techniques
   are: are UDP floods
       and ICMP floods), Protocol Attacks (This floods)

   2.  protocol attacks aims (which aim to use up actual server resources, often used resources;
       often-used techniques are SYN floods, fragmented packet attacks,
       and Ping "ping of Death death" [RFC4949]) and
   Application Layer Attacks (this attack aims

   3.  application-layer attacks (which aim to bring down a server, such
       as the webserver). a web server)

   DDoS attacks can thus stifle freedom of expression, expression and complicate the
   ability of independent media and human rights organizations to
   exercise their right to (online) freedom of association, while
   facilitating the ability of governments to censor dissent.  When it
   comes to comparing DDoS attacks to protests in offline life, it is
   important to remember that only a limited number of DDoS attacks
   involved
   solely involved willing participants.  In the overwhelming majority
   of cases, the clients are hacked hosts of unrelated parties that
   have not consented to being part of a DDoS (for exceptions exceptions, see
   Operation
   Abibil [Abibil] Ababil [Ababil] or the Iranian Green Movement Movement's DDoS
   campaign at election time [GreenMovement]).  In addition,
   DDoS attacks are increasingly used as an extortion tactic.

   All of these issues seem to suggest that the IETF should try to
   ensure that their protocols cannot be used for DDoS attacks, which attacks; this is
   consistent with the long-standing IETF consensus that DDoS is an
   attack that protocols should mitigate them to the extent they can [BCP72].
   Decreasing the number of vulnerabilities in protocols and (outside of
   the IETF) the number of bugs in the network stacks of routers or
   computers could address this issue.  The IETF can clearly play a role
   in bringing about some of these changes changes, but the IETF cannot be
   expected to take a positive stance on (specific) DDoS attacks, attacks or to
   create protocols to that enable some attacks and inhibit others.  What
   the IETF can do is critically reflect on its role in the development
   of the Internet, Internet and how this impacts the ability of people to excercise
   exercise their human rights, such as freedom of expression.

6.  Model for developing human rights protocol considerations Developing Human Rights Protocol Considerations

   This section outlines a set of human rights protocol considerations
   for protocol developers.  It provides questions that engineers should
   ask themselves when developing or improving protocols if they want to
   understand their impact on human rights impact. rights.  It should however should, however, be
   noted that the impact of a protocol cannot solely be solely deduced from its
   design, but
   design; its usage and implementation should also be studied to form a
   full assessment of the impact of the protocol on human rights impact assessment. rights.

   The questions are based on the research performed by the hrpc HRPC
   Research Group.  This research group which has been was documented before prior to the writing of
   these considerations.  The research establishes that human rights
   relate to standards and
   protocols and protocols; it also offers a common vocabulary
   of technical concepts that impact human rights and how these
   technical concept concepts can be combined to ensure that the Internet
   remains an enabling environment for human rights.  With this the contours of this, a model
   for developing human rights protocol considerations has taken shape.

6.1.  Human rights threats Rights Threats

   Human rights threats on the Internet come in a myriad of forms.
   Protocols and standards can either harm or enable the right to
   freedom of
   expression, expression; the right to non-discrimination, non-discrimination; the right to
   equal protection, protection; the right to participate in cultural life, arts arts,
   and science, science; the right to freedom of assembly and association, association; and
   the right to security.  An
   end-user end user who is denied access to certain
   services, data data, or websites may be unable to disclose vital
   information about malpractice on the malpractices part of a government or other
   authority.  A person whose communications are monitored may be
   prevented from exercising their right to freedom of association or participate
   participation in political processes [Penney].  In a worst-case
   scenario, protocols that leak information can lead to physical
   danger.  A realistic example to consider is when when, based on
   information gathered by state agencies through information leakage in
   protocols, individuals perceived as threats to the state are
   subjected to torture or torture, extrajudicial killing killings, or detention on the basis of information
   gathered by state agencies through information leakage in protocols. detention.

   This section details several 'common' "common" threats to human rights,
   indicating how each of these can lead to harm to, or violations of,
   human rights violations/
   harms and present rights.  It also presents several examples of how these threats
   to human rights materialize on the Internet.  This threat modeling is
   inspired by [RFC6973] Privacy ("Privacy Considerations for Internet Protocols,
   Protocols"), which is based on the security threat analysis.  This method
   is by no means a perfect solution for assessing human rights risks in
   Internet protocols and systems; it is however is, however, the best approach
   currently available.  Certain specific human rights threats are
   indirectly considered in Internet protocols as part of the their security
   considerations [BCP72], but privacy guidelines [RFC6973] or reviews,
   let alone human rights impact the assessments of the impact of protocols on human rights,
   are not standardized or implemented.

   Many threats, enablers enablers, and risks are linked to different rights.
   This is not unsurprising surprising if one takes into account that human rights
   are interrelated, interdependent interdependent, and indivisible.  Here however  Here, however,
   we're not discussing all human rights rights, because not all human rights
   are relevant to ICTs in general and to protocols and standards in
   particular
   [Bless]: "The [Bless1]:

      The main source of the values of human rights is the International
      Bill of Human Rights that is composed of the Universal Declaration
      of Human Rights [UDHR] along with the International Covenant on
      Civil and Political Rights [ICCPR] and the International Covenant
      on Economic, Social and Cultural Rights [ICESCR].  In the light of
      several cases of Internet censorship, the Human Rights Council
      Resolution 20/8 was adopted in 2012 [UNHRC2016], affirming ".

      protected online. . . " . online ..."  In 2015, the Charter of Human Rights and
      Principles for the Internet [IRP] was developed and released.
      According to these documents, some examples of human rights
      relevant for ICT systems are human dignity (Art. 1 UDHR),
      non-discrimination (Art. 2), rights to life, liberty and security
      (Art. 3), freedom of opinion and expression (Art. 19), freedom of
      assembly and association (Art. 20), rights to equal protection,
      legal remedy, fair trial, due process, presumed innocent
      (Art. 7-11), appropriate social and international order (Art. 28),
      participation in public affairs (Art. 21), participation in
      cultural life, protection of intellectual property (Art. 27), and
      privacy (Art. 12)." 12).

   A partial catalog of human rights related to ICTs, including economic
   rights, can be found in [Hill2014].

   This is by no means an attempt to exclude specific rights or
   prioritize some rights over others.  If other rights seem relevant,
   please contact the authors. authors of this document.

6.2.  Guidelines for human rights considerations Human Rights Considerations

   This section provides guidance for document authors in the form of a
   questionnaire about protocols and their (potential) impact.  The
   questionnaire may be useful at any point in the design process,
   particularly after document authors have developed a high-level
   protocol model as described in [RFC4101].  These guidelines do not
   seek to replace any existing referenced specifications, but rather specifications; rather, they
   contribute to them and look at the design process from a human rights
   perspective.

   Protocols and Internet Standard Standards might benefit from a documented
   discussion of potential human rights risks arising from potential
   misapplications of the protocol or technology described in the RFC. RFC in
   question.  This might be coupled with an Applicability Statement for
   that RFC.

   Note that the guidance provided in this section does not recommend
   specific practices.  The range of protocols developed in the IETF is
   too broad to make recommendations about particular uses of data or
   how human rights might be balanced against other design goals.
   However, by carefully considering the answers to the following
   questions, document authors should be able to produce a comprehensive
   analysis that can serve as the basis for discussion on whether the
   protocol adequately takes specific human rights threats into account.
   This guidance is meant to help the thought process of a human rights
   analysis; it does not provide specific directions for how to write a
   human rights protocol considerations section (following the example
   set in [RFC6973]), and the addition of a human rights protocol
   considerations section has also not yet been proposed.  In
   considering these questions, authors will need to be aware of the
   potential of technical advances or the passage of time to undermine
   protections.  In general, considerations of rights are likely to be
   more effective if they are considered given a purpose and specific
   use cases, rather than as abstract absolute goals.

6.2.1.  Connectivity

   Question(s):

   Questions:

   -  Does your protocol add application-specific functions to
      intermediary nodes?

   -  Could this functionality be added to end nodes instead of
      intermediary nodes?

   -  Is your protocol optimized for low bandwidth and high latency high-latency
      connections?

   -  Could your protocol also be developed in a stateless manner?

   Explanation:  The end-to-end principle [Saltzer] holds that 'the "the
      intelligence is end to end rather than hidden in the network' network"
      [RFC1958].  The end-to-end principle is important for the
      robustness of the network and innovation.  Such robustness of the
      network is crucial to enabling human rights like freedom of
      expression.

   Example:  Middleboxes (which can be Content Delivery Networks,
   Firewalls, NATs content delivery networks,
      firewalls, NATs, or other intermediary nodes that provide
      "services" other
   'services' than routing) serve many legitimate purposes.
      But the protocols guiding them, them can influence individuals' ability
      to communicate online freely and privately.  The potential for abuse and
      abuse, intentional and unintentional censoring censoring, and limiting
      permissionless
   innovation, innovation -- and thus ultimately thus, ultimately, the impact of
      middleboxes on the Internet as a place of unfiltered, unmonitored
      freedom of speech, speech -- is real.

   Impacts:

   -  Right to freedom of expression

   -  Right to freedom of assembly and association

6.2.2.  Privacy

   Question(s):

   Questions:

   -  Did you have a look at the Guidelines guidelines in the Privacy Section 7 of [RFC6973]
      ("Privacy Considerations for Internet Protocols [RFC6973] section 7? Protocols")?

   -  Could your protocol in any way impact the confidentiality of
      protocol metadata?
   -  Could your protocol counter traffic analysis?

   -  Could your protocol improve data minimization?

   -  Does your document identify potentially sensitive logged data logged by
      your protocol and/or for how long that data needs to be retained
      for technical reasons?

   Explanation: Privacy  "Privacy" refers to the right of an entity (normally a
      person), acting in on its own behalf, to determine the degree to
      which it will interact with its environment, including the degree
      to which the entity is willing to share its personal information
      with others. others [RFC4949].  If a protocol provides insufficient
      privacy protection protection, it may have a negative impact on freedom of
      expression as users self-
   censor self-censor for fear of surveillance, surveillance or find
      themselves unable to express themselves freely.

   Example:  See [RFC6973] [RFC6973].

   Impacts:

   -  Right to freedom of expression

   -  Right to non-discrimination

6.2.3.  Content agnosticism

   Question(s): Agnosticism

   Questions:

   -  If your protocol impacts packet handling, does it use user data
      (packet data that is not included in the header)?  Is it
   making

   -  Does your protocol make decisions based on the payload of the
      packet?

   -  Does your protocol prioritize certain content or services over
      others in the routing process ? process?

   -  Is the protocol transparent about the prioritization that is made
      (if any)?

   Explanation: Content agnosticism  "Content agnosticism" refers to the notion that network
      traffic is treated identically regardless of payload, with some
   exception where
      exceptions when it comes to effective traffic handling, handling -- for instance
   where it comes to delay tolerant
      instance, delay-tolerant or delay sensitive packets, delay-sensitive packets based on the
      header.

   Example:  Content agnosticism prevents payload-based discrimination
      against packets.  This is important because changes to this
      principle can lead to a two-tiered Internet, where certain packets
      are prioritized over others based on the basis of their content.  Effectively  Effectively,
      this would mean that although all users are entitled to receive
      their packets at a certain speed, some users become more equal
      than others.

   Impacts:

   -  Right to freedom of expression

   -  Right to non-discrimination

   -  Right to equal protection

6.2.4.  Security

   Question(s):

   Questions:

   -  Did you have a look at Guidelines [BCP72] ("Guidelines for Writing RFC Text
      on Security Considerations [BCP72]? Considerations")?

   -  Have you found any "attacks attacks that are somewhat related to your
      protocol yet considered out of scope of for your document?

   -  Would these attacks be pertinent to the human rights
   enabling features of the Internet
      that enable human rights (as described throughout this document)?

   Explanation:  Most people speak of security as if it were a single
      monolithic property of a protocol or system, system; however, upon
      reflection one realizes that it is clearly not true.  Rather,
      security is a series of related but somewhat independent
      properties.  Not all of these properties are required for every
      application.  Since communications are carried out by systems and
      access to systems is through communications channels, these goals
      obviously interlock, but they can also be independently provided
      [BCP72].

   Example:  See [BCP72].

   Impacts:

   -  Right to freedom of expression

   -  Right to freedom of assembly and association

   -  Right to non-discrimination

   -  Right to security

6.2.5.  Internationalization

   Question(s):

   Questions:

   -  Does your protocol have text strings that have to be understood or
      entered by humans?

   -  Does your protocol allow Unicode?  If so, do you accept texts in
      one charset (which must be UTF-8), UTF-8) or several (which is dangerous
      for interoperability)?

   -  If character sets or encodings other than UTF-8 are allowed, does
      your protocol mandate
   a proper tagging of the charset?

   -  Did you have a look at [RFC6365]?

   Explanation: Internationalization  "Internationalization" refers to the practice of making
      protocols, standards, and implementations usable in different
      languages and scripts (see Localization).  In Section 6.2.12 ("Localization")).  "In
      the IETF,
   internationalization 'internationalization' means to add or improve the
      handling of non-
   ASCII non-ASCII text in a protocol.  [RFC6365] protocol" [RFC6365].

      A different perspective, more appropriate to protocols that are
      designed for global use from the beginning, is the definition used
      by W3C: the W3C [W3Ci18nDef]: "Internationalization is the design and
      development of a product, application or document content that
      enables easy localization for target audiences that vary in
      culture, region, or language."  {{W3Ci18nDef}}

      Many protocols that handle text only handle one charset
      (US-ASCII), or they leave the question of what CCS coded character set
      (CCS) and encoding are used up to local guesswork (which leads, of
      course, to interoperability problems). problems) [RFC3536].  If multiple
      charsets are permitted, they must be explicitly identified
      [RFC2277].  Adding non-ASCII text to a protocol allows the
      protocol to handle more scripts, hopefully representing users across all scripts in use in
      the world.  In today's world, that is normally best accomplished
      by allowing Unicode encoded in UTF-8 only.

      In the current IETF policy [RFC2277], internationalization is
      aimed at user-facing strings, not protocol elements, such as the
      verbs used by some text-based protocols.  (Do note that some strings
      strings, such as identifiers, are both content and protocol elements, such as the identifiers.)
      elements.)  If the Internet wants to be a global network of
      networks, the protocols should work with other languages other than
      English and other character sets other than latin Latin characters.  It is
      therefore crucial that at least the content carried by the
      protocol can be in any script, script and that all scripts are treated
      equally.

   Example:  See localization Section 6.2.12 ("Localization").

   Impacts:

   -  Right to freedom of expression

   -  Right to political participation

   -  Right to participate in cultural life, arts arts, and science

6.2.6.  Censorship resistance

   Question(s): Resistance

   Questions:

   -  Does this protocol introduce new identifiers or reuse existing
      identifiers (e.g.  MAC (e.g., Media Access Control (MAC) addresses) that
      might be associated with persons or content?

   -  Does your protocol make it apparent or transparent when access to
      a resource it is restricted?

   -  Can your protocol contribute to filtering in such a way that it
      could be implemented to censor data or services?  Could this  If so, could
      your protocol be designed to ensure that this doesn't happen?

   Explanation: Censorship resistance  "Censorship resistance" refers to the methods and
      measures to prevent Internet censorship.

   Example: In the development of the  When IPv6 protocol it was discussed to
   embed developed, embedding a Media Access Control (MAC) MAC address into
      unique IP addresses. addresses was discussed.  This would make makes it possible possible, per
      [RFC4941], for 'eavesdroppers "eavesdroppers and other information collectors to
      identify when different addresses used in different transactions
      actually correspond to the same node.  [RFC4941] node."  This is why Privacy Extensions privacy
      extensions for Stateless Address Autoconfiguration stateless address autoconfiguration in IPv6
      [RFC4941] have been introduced.  [RFC4941]

      Identifiers of content exposed within a protocol might be used to
      facilitate censorship, as in the case of Application Layer based application-layer-based
      censorship, which affects protocols like HTTP.  Denial or
      restriction of access can be made apparent by the use of status
      code 451 - which
   allows 451, thereby allowing server operators to operate with
      greater transparency in circumstances where issues of law or
      public policy affect their operation [RFC7725].

   Impacts:

   -  Right to freedom of expression

   -  Right to political participation

   -  Right to participate in cultural life, arts arts, and science

   -  Right to freedom of assembly and association

6.2.7.  Open Standards

   Question(s):

   Questions:

   -  Is your protocol fully documented in such a way that it could be
      easily implemented, improved, built upon upon, and/or further
      developed?

   -  Do you depend on proprietary code for the implementation, running running,
      or further development of your protocol?

   -  Does your protocol favor a particular proprietary specification
      over technically equivalent and competing specification(s), specification(s) -- for instance
      instance, by making any incorporated vendor specification
      "required" or "recommended" [RFC2026]?

   -  Do you normatively reference another standard that is not
      available without cost (and could it possible be done without)? you possibly do without it)?

   -  Are you aware of any patents that would prevent your standard from
      being fully implemented
   [RFC3979] [RFC6701]? [RFC6701] [RFC8179]?

   Explanation:  The Internet was able to be developed into the global
      network of networks because of the existence of open,
      non-proprietary standards [Zittrain].  They are crucial for
      enabling interoperability.  Yet, open standards are not explicitly
      defined within the IETF.  On the subject, [RFC2026] states: Various states the
      following: "Various national and international standards bodies,
      such as ANSI, ISO, IEEE, and ITU-
   T, ITU-T, develop a variety of protocol
      and service specifications that are similar to Technical
      Specifications defined defined" at the IETF.  National  "National and international
      groups also publish "implementors' agreements" 'implementors' agreements' that are analogous
      to Applicability Statements, capturing a body of
   implementation-specific implementation-
      specific detail concerned with the practical application of their
      standards.  All of these are considered to be
   "open 'open external standards"
      standards' for the purposes of the Internet Standards
   Process. Process."
      Similarly, [RFC3935] does not define open standards but does
      emphasize the importance of 'open process': "open process": any interested person
      can participate in the work, know what is being decided, and make
      his or her voice heard on the issue.  Part of this principle is
      the IETF's commitment to making its documents, WG mailing lists,
      attendance lists, and meeting minutes publicly available on the
      Internet.

      Open standards are important important, as they allow for permissionless
      innovation, which in turn is important to maintain for maintaining the freedom
      and ability to freely create and deploy new protocols on top of
      the communications constructs that currently exist.  It is at the
      heart of the Internet as we know it, and to maintain its
      fundamentally open nature, we need to be mindful of the need for
      developing open standards.

      All standards that need to be normatively implemented should be
      freely available and with should provide reasonable protection for against
      patent infringement claims, so that it can also be implemented in open source
      open-source or free software.  Patents have often held back open
      standardization or have been used against those deploying open
      standards, particularly in the domain of cryptography [newegg]. [Newegg].
      An exemption of this is sometimes made when a protocol is standardized that normatively
      relies on
   speficiations specifications produced by others other SDOs that are not
      freely available. available is standardized.  Patents in open standards or in
      normative references to other standards should have a patent
      disclosure [notewell], royalty-free licensing [patentpolicy], or
      some other form of reasonable protection.  Reasonable patent
      protection should includes include, but is not limited to to, cryptographic
      primitives.

   Example:  [RFC6108] describes a system deployed by Comcast, an ISP,
      for providing critical end-user notifications to web browsers, which has been deployed by Comcast, an
   Internet Service Provider (ISP). browsers.
      Such a notification system is being used to provide near-immediate
      almost-immediate notifications to customers, such as to
   warn warning them
      that their traffic exhibits patterns that are indicative of
      malware or virus infection.  There are other proprietary systems
      that can perform such notifications, but those systems utilize
      Deep Packet Inspection (DPI) technology.  In contrast to DPI, this document
      [RFC6108] describes a system that does not rely upon DPI, DPI and is
      instead based
   in on open IETF standards and open source open-source applications.

   Impacts:

   -  Right to freedom of expression

   -  Right to participate in cultural life, arts arts, and science

6.2.8.  Heterogeneity Support

   Question(s):

   Questions:

   -  Does your protocol support heterogeneity by design?

   -  Does your protocol allow for multiple types of hardware?

   -  Does your protocol allow for multiple types of application
      protocols?

   -  Is your protocol liberal in what it receives and handles?

   -  Will it your protocol remain usable and open if the context changes?

   -  Does your protocol allow
   there to be well-defined extension points?  Do  If so, do
      these extension points allow for open innovation?

   Explanation: The  [FIArch] notes the following: "The Internet is
      characterized by heterogeneity on many levels: devices and nodes,
      router scheduling algorithms and queue management mechanisms,
      routing protocols, levels of multiplexing, protocol versions and
      implementations, underlying link layers (e.g., point-to-point,
      multi-access links, wireless, FDDI, etc.), in the traffic mix and
      in the levels of congestion at different times and places.
      Moreover, as the Internet is composed of autonomous organizations
      and Internet internet service providers, each with their own separate
      policy concerns, there is a large heterogeneity of administrative
      domains and pricing structures. structures."  As a result, as also noted in
      [FIArch], the heterogeneity principle proposed in [RFC1958] needs
      to be supported by design [FIArch]. design.

6.2.9.  Anonymity

   Question(s):

   Question:

   -  Did you have a look at the Privacy [RFC6973] ("Privacy Considerations for
      Internet Protocols [RFC6973], Protocols"), especially section Section 6.1.1 ? of that document?

   Explanation: Anonymity  "Anonymity" refers to the condition of an identity
      being unknown or concealed [RFC4949].  Even though full anonymity
      is hard to achieve, it is a non-binary concept.  Making pervasive
      monitoring and tracking harder is important for many users as well
      as for the IETF [RFC7258].  Achieving a higher level of anonymity
      is an important feature for many end-users, end users, as it allows them
      different degrees of privacy online.

   Example: Often protocols  Protocols often expose personal data, data; it is therefore
      important to consider ways to mitigate the obvious privacy impacts. impacts on
      privacy.  A protocol that uses data that could help identify a
      sender (items of interest) should be protected from third parties.
      For instance instance, if one wants to hide the source/destination IP
      addresses of a packet, the use of IPsec in tunneling mode (e.g.,
      inside a virtual private network) VPN) can
   be helpful to help protect from against third parties likely to
      eavesdrop packets exchanged between the tunnel endpoints.

   -  Right to political participation

   -  Right to freedom of assembly and association

   -  Right to security

6.2.10.  Pseudonymity

   Question(s):

   Questions:

   -  Have you considered the Privacy [RFC6973] ("Privacy Considerations for
      Internet Protocols [RFC6973], Protocols"), especially section Section 6.1.2 ? of that document?

   -  Does the protocol collect personally derived data?
   -  Does the protocol generate or process anything that can be, or
      that can be tightly correlated with, personally identifiable
      information?

   -  Does the protocol utilize data that is personally-derived, i.e. personally derived, i.e.,
      derived from the interaction of a single person, person or from their
      device or address?

   -  Does this protocol generate personally derived data, and if so data?  If so, how
      will that data be handled?

   Explanation:  Pseudonymity - -- the ability to use a persistent
      identifier that is not immediately linked to one's offline identity" straight away -
      identity -- is an important feature for many end-users, end users, as it
      allows them different degrees of disguised identity and privacy
      online.

   Example: Designing  When designing a standard that exposes personal data, it is
      important to consider ways to mitigate the obvious impacts.  While
      pseudonyms cannot easily be simply reverse engineered - reverse-engineered -- for example,
      some early approaches simply took approaches used such techniques as simple hashing of IP
   addreses, these
      addresses that could then in turn be simply easily reversed by generating a
      hash for each potential IP address and comparing it to the
      pseudonym - -- limiting the exposure of personal data remains
      important.

   Pseudonymity

      "Pseudonymity" means using a pseudonym instead of one's "real"
      name.  There are many reasons for users to use pseudoyms, pseudonyms -- for instance to:
      instance, to hide their gender, gender; protect themselves against harassment,
      harassment; protect their families' privacy, privacy; frankly discuss sexuality,
      sexuality; or develop a an artistic or journalistic persona without
      retribution from an employer, (potential) customers, or social surrounding.
   [geekfeminism]
      surroundings [geekfeminism].  The difference between anonymity and
      pseudonymity is that a pseudonym often is often persistent.
      "Pseudonymity is strengthened when less personal data can be
      linked to the pseudonym; when the same pseudonym is used less
      often and across fewer contexts; and when independently chosen
      pseudonyms are more frequently used for new actions (making them,
      from an observer's or attacker's perspective, unlinkable)."

   -  Right to freedom of assembly and association

6.2.11.  Accessibility

   Question(s):

   Questions:

   -  Is your protocol designed to provide an enabling environment for
      people who are not able-bodied?

   -  Have you looked at the W3C Web Accessibility Initiative
      [W3CAccessibility] for examples and guidance?

   Explanation:  The Internet is fundamentally designed to work for all
      people, whatever their hardware, software, language, culture,
      location, or physical or mental ability.  When the Internet meets
      this goal, it is accessible to people with a diverse range of
      hearing, movement, sight, and cognitive ability abilities
      [W3CAccessibility].
   Sometimes  Sometimes, in the design of protocols,
      websites, web technologies, or web tools, barriers are created that exclude
      people from using the
   Web. Web are created.

   Example:  The HTML protocol as defined in [HTML5] specifically
      requires that (with a few exceptions) every image must have an alt
      "alt" attribute (with a few
   exceptions) to ensure that images are accessible for people
      that cannot themselves decipher non-text content in web pages.

   -  Right to freedom of assembly and association

   -  Right to education

   -  Right to political participation

6.2.12.  Localization

   Question(s):

   Questions:

   -  Does your protocol uphold the standards of internationalization?

   -  Have made you taken any concrete steps towards localizing your protocol
      for relevant audiences?

   Explanation: Localization  Per [W3Ci18nDef], "Localization refers to the
      adaptation of a product, application or document content to meet
      the language, cultural and other requirements of a specific target
      market (a locale)
   [W3Ci18nDef]. 'locale')."  It is also described as the practice of
      translating an implementation to make it functional in a specific
      language or for users in a specific locale (see Internationalization). Section 6.2.5
      ("Internationalization")).

   Example:  The Internet is a global medium, but many of its protocols
      and products are developed with a certain audience in mind, that mind; this
      audience often share shares particular characteristics like knowing how
      to read and write in ASCII and knowing English.  This limits the
      ability of a large part of the world's online population from using to use
      the Internet in a way that is culturally and linguistically
      accessible.  An example of a protocol that has taken into account
      the view that individuals like to have access to data in their
      native language can be found in [RFC5646].  This [RFC5646]; such a protocol labels would
      label the information content with an identifier for the language
      in which it is written.  And this
   allows written and would allow information to be presented
      in more than one language.

   Impacts:

   -  Right to non-discrimination

   -  Right to participate in cultural life, arts arts, and science

   -  Right to freedom of expression

6.2.13.  Decentralization

   Question(s):

   Questions:

   -  Can your protocol be implemented without one single point of
      control?

   -  If applicable, can your protocol be deployed in a federated
      manner?

   -  What is the potential for discrimination against users of your
      protocol?  How can the use of

   -  Can your protocol be used to negatively implicate users? users (e.g.,
      incrimination, accusation)?

   -  Does your protocol create additional centralized points of
      control?

   Explanation:  Decentralization is one of the central technical
      concepts of the architecture of the networks, networks and is embraced as such
      by the IETF [RFC3935].  It refers to the absence or minimization
      of centralized points of control; a control -- "a feature that is assumed to
      make it easy for new users to join and new uses to unfold unfold"
      [Brown].  It also reduces issues surrounding single points of failure,
      failure and distributes the network such that it continues to
      function if one or several nodes are disabled.  With the
      commercialization of the Internet in the early 1990's 1990s, there has
      been a slow move to move trend toward moving away from decentralization, to the
      detriment of the any technical benefits of that having a decentralized Internet.
      Internet otherwise provides.

   Example:  The bits traveling the Internet are increasingly
      susceptible to monitoring and censorship, from both governments
      and Internet
   service providers, ISPs, as well as third (malicious) parties.  The ability to
      monitor and censor is further enabled by the increased centralization
      of the network that creates network, creating central infrastructure points that can be
      tapped in to. into.  The creation of peer-to-peer P2P networks and the development of
      voice-over-IP protocols using peer-
   to-peer P2P technology in combination with a
      distributed hash table (DHT) for scalability are examples of how
      protocols can preserve decentralization [Pouwelse].

   Impacts:

   -  Right to freedom of expression

   -  Right to freedom of assembly and association

6.2.14.  Reliability

   Question(s):

   Questions:

   -  Is your protocol fault tolerant?

   -  Does it your protocol degrade gracefully?

   -  Can your protocol resist malicious degradation attempts?

   -  Do you have a documented way to announce degradation?

   -  Do you have measures in place for recovery or partial healing from
      failure?

   -  Can your protocol maintain dependability and performance in the
      face of unanticipated changes or circumstances?

   Explanation:  Reliability ensures that a protocol will execute its
      function consistently and consistently, be error resistant as described, and
      function without unexpected result. results.  A system that is reliable
      degenerates gracefully and will have a documented way to announce
      degradation.  It also has mechanisms to recover from failure gracefully, and
      gracefully and, if applicable, to allow for partial healing.  It
      is important here to draw a distinction between random degradation
      and malicious degradation.  Many current attacks against TLS, for
      example, exploit TLS's ability to gracefully degrade to older
      cipher suites - suites; from a functional perspective, this ability is good.  From
      good, but from a security perspective, this it can be very bad.  As
      with confidentiality, the growth of the Internet and fostering
      innovation in services depends depend on users having confidence and trust
      [RFC3724] in the network.  For reliability reliability, it is necessary that
      services notify the users if a packet delivery fails.  In the case of
      real-time systems in addition to the reliable delivery systems, the protocol needs to safeguard timeliness. timeliness in
      addition to providing reliable delivery.

   Example:  In the modern IP stack structure, a reliable transport
      layer requires an indication that transport processing has
      successfully completed, such as the indication given by TCP's ACK
      message [RFC0793], [RFC793] and not simply an indication from the IP layer
      that the packet arrived.  Similarly, an application layer application-layer protocol
      may require an application-
   specific application-specific acknowledgement that contains,
      among other things, a status code indicating the disposition of
      the request (See (see [RFC3724]).

   Impacts:

   -  Right to freedom of expression

   -  Right to security

6.2.15.  Confidentiality

   Question(s):

   Questions:

   -  Does this protocol expose information related to identifiers or
      data?  If so, does it do so to each of the other protocol
   entity entities
      (i.e., recipients, intermediaries, and enablers) [RFC6973]?

   -  What options exist for protocol implementers to choose to limit
      the information shared with each entity?

   -  What operational controls are available to limit the information
      shared with each entity?

   -  What controls or consent mechanisms does the protocol define or
      require before personal data or identifiers are shared or exposed
      via the protocol?  If no such mechanisms or controls are
      specified, is it expected that control and consent will be handled
      outside of the protocol?
   -  Does the protocol provide ways for initiators to share different
      pieces of information with different recipients?  If not, are
      there mechanisms that exist outside of the protocol to provide
      initiators with such control?

   -  Does the protocol provide ways for initiators to limit which
      information is shared with intermediaries?  If not, are there
      mechanisms that exist outside of the protocol to provide users
      with such control?

   -  Is it expected that users will have relationships that govern the
      use of the information (contractual or otherwise) with those who
      operate these intermediaries?

   -  Does the protocol prefer encryption over clear text cleartext operation?

   -  Does the protocol provide ways for initiators to express
      individuals' preferences to recipients or intermediaries with
      regard to the collection, use, or disclosure of their personal
      data?

   Explanation: Confidentiality  "Confidentiality" refers to keeping your a user's data
      secret from unintended listeners [BCP72].  The growth of the
      Internet depends on users having confidence that the network
      protects their personal data [RFC1984].

   Example:  Protocols that do not encrypt their payload make the entire
      content of the communication available to the idealized attacker
      along their path. path [RFC7624].  Following the advice in [RFC3365],
      most such protocols have a secure variant that encrypts the
      payload for confidentiality, and these secure variants are seeing
      ever-wider deployment.  A noteworthy exception is DNS [RFC1035],
      as DNSSEC
   [RFC4033]does [RFC4033] does not have confidentiality as a
      requirement.  This implies that, in the absence of changes to the
      protocol as presently under development in the IETF's DNS Private
      Exchange (DPRIVE) working
   group, Working Group, all DNS queries and answers
      generated by the activities of any protocol are available to the
      attacker.  When store-and-forward protocols are used (e.g., SMTP
      [RFC5321]), intermediaries leave this data subject to observation
      by an attacker that has compromised these intermediaries, unless
      the data is encrypted end-to-end end to end by the application-layer protocol
      or the implementation uses an encrypted store for this data
      [RFC7624].

   Impacts:

   -  Right to privacy

   -  Right to security

6.2.16.  Integrity

   Question(s):

   Questions:

   -  Does your protocol maintain, assure assure, and/or verify the accuracy of
      payload data?

   -  Does your protocol maintain and assure the consistency of data?

   -  Does your protocol in any way allow for the data to be (intentionally
      or unintentionally) altered?

   Explanation: Integrity  "Integrity" refers to the maintenance and assurance of
      the accuracy and consistency of data to ensure that it has not
      been (intentionally or unintentionally) altered.

   Example:  Integrity verification of data is important to prevent for preventing
      vulnerabilities and attacks, like man-in-the-middle-attacks. attacks such as man-in-the-middle attacks.
      These attacks happen when a third party (often for malicious
      reasons) intercepts a communication between two parties, inserting
      themselves in the middle and changing the content of the data.  In practice
      practice, this looks as follows:

      Alice wants to communicate with Bob.
      Corinne forges and sends a message to Bob, impersonating Alice.
      Bob cannot see that the data from Alice was altered by Corinne.
      Corinne intercepts and alters the communication as it is sent
      between Alice and Bob.
      Corinne is able to control the communication content.

   Impacts:

   -  Right to freedom of expression

   -  Right to security

6.2.17.  Authenticity

   Question(s):

   Questions:

   -  Do you have sufficient measures in place to confirm the truth of
      an attribute of an entity or of a single piece of data or entity? data?

   -  Can the attributes get garbled along the way (see security)? Section 6.2.4
      ("Security"))?

   -  If relevant relevant, have you implemented IPsec, DNSsec, HTTPS DNSSEC, HTTPS, and other Standard Security Best
   Practices?
      standard security best practices?

   Explanation:  Authenticity ensures that data does indeed come from
      the source it claims to come from.  This is important to prevent for
      preventing (1) certain attacks or (2) unauthorized access to, and
      use of of, data.

   Example:  Authentication of data is important to prevent for preventing
      vulnerabilities and attacks, like man-in-the-middle-attacks. attacks such as man-in-the-middle attacks.
      These attacks happen when a third party (often for malicious
      reasons) intercepts a communication between two parties, inserting
      themselves in the middle and posing as both parties.  In practice practice,
      this looks as follows:

      Alice wants to communicate with Bob.
      Alice sends data to Bob.
      Corinne intercepts the data sent to Bob.
      Corinne reads (and potentially alters) and alters the message to Bob.
      Bob cannot see that the data did not come from Alice but instead
      came from Corinne.

      When there is proper authentication authentication, the scenario would be as
      follows:

      Alice wants to communicate with Bob.
      Alice sends data to Bob.
      Corinne intercepts the data sent to Bob.
      Corinne reads and alters the message to Bob.
      Bob can see that the data did not come from Alice but instead came
      from Corinne.

6.2.18.  Adaptability

   Question(s):

   Questions:

   -  Is your protocol written in such a way that is it would be easy for
      other protocols to be developed on top of it, it or to interact
      with it?

   -  Does your protocol impact permissionless innovation?  See
   'Connectivity' above. innovation (see
      Section 6.2.1 ("Connectivity") above)?

   Explanation:  Adaptability is closely interrelated with
      permissionless
   innovation, innovation; both maintain the freedom and ability
      to freely create and deploy new protocols on top of the
      communications constructs that currently exist.  It  Permissionless
      innovation is at the heart of the Internet as we know it,
   and to it.  To
      maintain its the Internet's fundamentally open nature, nature and ensure that
      it can continue to develop, we need to be mindful of the impact of
      protocols on maintaining or reducing permissionless

6.2.19.  Outcome Transparency

   Question(s):

   Question:

   -  Are the effects of your protocol fully and easily comprehensible,
      including with respect to unintended consequences of protocol
      choices?

   Explanation: certain  Certain technical choice choices may have unintended
      consequences.

   Example: lack  Lack of authenticity may lead to lack of integrity and
      negative externalities, of which externalities; spam is an example.  Lack of data that
      could be used for billing and accounting can lead to so-called
      "free" arrangements which that obscure the actual costs and distribution
      of the costs, costs -- for example example, (1) the barter arrangements that are
      commonly used for Internet interconnection; interconnection and (2) the commercial
      exploitation of personal data for targeted advertising advertising, which is
