privecsg ecsg 4 IEEE 802 Internet Privacy Tutorial - Summary The Tutorial provided an update on the recent concerns about Internet privacy, the actions that IETF is taking, and the guidelines that are being followed when developing new specifications (e.g. RFC 6973) Highlighted Privacy concerns applicable specifically to Link Layer technologies, and provided suggestions on how IEEE 802 can help addressing them The idea of developing an IEEE 802 recommended practices document, similar to the one produced by IETF (RFC Privacy Considerations for Internet Protocols) was suggested and supported by several IEEE 802 members from different WGs

privecsg ecsg 5 IEEE 802 EC Privacy SG – Background Creation of an Executive Committee Study Group on Privacy Recommendations ( ) –Juan Carlos Zuniga appointed as Chair of SG Chartered to run until November 2014 with an expectation of renewal through March 2015 –Next IEEE 802 Plenary meeting in November 2014 – San Antonio, TX Advancing work with teleconferences and discussions

privecsg ecsg 6 IEEE 802 EC Privacy SG – Scope The IEEE 802 Executive Committee (EC) Privacy Recommendation SG will study privacy issues related to IEEE 802 technologies and consider the need for a recommended practice applicable to IEEE 802 protocols. If such a need is identified, the SG will determine whether the IEEE 802 criteria for standards development (CSD) support the initiation of a project and, if so, it will prepare a PAR for consideration by the IEEE 802 Executive Committee.

privecsg ecsg 7 Call for Contributions Current topics being considered by SG include: (1) Privacy Issues at Link Layer (2) Threat Model for Privacy at Link Layer (3) Proposals regarding functionalities in IEEE 802 protocols to improve Privacy (4) Proposals regarding measuring levels of Privacy on Internet protocols (5) Implications of MAC address changes (6) Other…

privecsg ecsg 8 8 Trial on IETF and IEEE meetings Suggestion to perform an opt-in trial on IETF and IEEE meetings networks to assess performance and implications of user’s MAC address randomization –Similar to “ietf-v6ONLY” SSID –Should assess implications on collisions, DHCP/ND states, router/bridge tables, etc. –Details to be worked out…
