Draft Charter

Background

Privacy is an increasingly desirable and often necessary property for Internet technologies. Evidence suggests that attacks on societal, community, and individual privacy occur with non-negligible frequency, as discussed in detail in RFC 7258 and in protocol-specific documents such as RFC 7626. Pervasive monitoring [RFC 7258], is a well known attack on privacy at incredible scale. The IETF and IAB responses to such attacks is to push for widespread end-to-end encryption. Understanding attacks on privacy and the costs of addressing them is critical for ensuring the longevity, usability, and viability of Internet technologies.

Alongside such work the emergence of global and region-specific legislation in this area e.g. GDPR provides further motivation for enhancing available privacy techniques (beyond end-to-end encryption), advancing the state-of-the-art for privacy in protocols, and for assessing privacy of existing protocols.

Objectives

The Privacy Enhancements and Assessments Research Group (PEARG) is a general forum for discussing and reviewing privacy enhancing technologies for network protocols and distributed systems in general, and for the IETF in particular. The PEARG serves as a bridge between theory and practice, bringing new privacy-enhancing technologies to the Internet community and promoting an understanding of the use and applicability of these mechanisms via Informational RFCs (in the tradition of HMAC [RFC 2104]). Our goal is to provide a forum for discussion and analyzing the cryptographic and practical aspects of privacy protocols, and to offer guidance on the use of emerging techniques and new uses of existing ones. IETF working groups developing protocols that include privacy technology elements are welcome to bring questions concerning the protocols to the PEARG for advice.

The Assessments objective of PEARG will include partaking in the following tasks:

1) Reviewing privacy properties (informed by but not limited to the analysis in RFC6973) of existing and emerging IETF protocols,

2) Developing specifications in the tradition of RFC 6973 that offer guidance for protocol design and development and advice on privacy-enhancement.

This work will involve outreach to ensure close cooperation with similar and related efforts in IETF.

Meetings

The PEARG will meet two to three times per year, as deemed necessary by the chairs and according to demand. At least one PEARG meeting will be co-located with an IETF meeting per year. The PEARG will also meet collocated with relevant academic conferences, such as the Privacy Enhancing Technologies Symposium (PETS), yearly if possible. Participation is open to all.

Meetings are by default open with open attendance and published proceedings, with remote participation and recording as provided by the meeting venue, according to the IRTF’s IPR policy.

The chairs may at times appoint at their pleasure “closed” design teams with lesser reporting requirements (though results will be open). This will allow for some limited discussions in which participants require extra privacy. This does not relax the Note Well: for all activities of the RG, as for all other activities of IRTF, the Note Well applies https://www.ietf.org/about/note-well/.

Collaborations

PEARG will actively engage with academic and open source (e.g. Tor project, EFF, OTF) communities and encourage specification of key privacy-enhancing technologies in Informational or Experimental RFCs. Example current emerging technologies where interest is solicited include:

  1. Differential privacy techniques applied to networked and distributed systems
  2. Anti-fingerprinting techniques
  3. Potential uses of multi-party computation (MPC) for privacy

PEARG is related to security and cryptographic protocols in the IETF and IRTF. Among the IETF working groups, PEARG will collaborate to ensure and encourage collaboration so that desirable privacy properties are upheld for the Internet community. PEARG will also collaborate with the CFRG to ensure cryptographic techniques and algorithms are used appropriately for their intended purpose.

Side meeting at IETF 102

Saint-Denis room from 1820-1900 on Tuesday 17th July 2018

Agenda is:

  • Welcome by the chairs
  • Review of the Proposed charter. Request for comments and discussion
  • Review of the list of WG with work or interest and topics sent to mailing list
    • Request for discussion on proposed work, particularly that outside of the IETF
    • Also requests for people willing to champion/shepherd along topics
  • Discussion of future meetings and co-location ideas

Meeting minutes are available in the mail archive.
