privecsg-15-0005-00-ecsg Participants, Patents, and Duty to Inform All participants in this meeting have certain obligations under the IEEE-SA Patent Policy. Participants [Note: Quoted text excerpted from IEEE-SA Standards Board Bylaws subclause 6.2]: Shall inform the IEEE (or cause the IEEE to be informed) of the identity of each holder of any potential Essential Patent Claims of which they are personally aware if the claims are owned or controlled by the participant or the entity the participant is from, employed by, or otherwise represents Personal awareness means that the participant is personally aware that the holder may have a potential Essential Patent Claim, even if the participant is not personally aware of the specific patents or patent claims Should inform the IEEE (or cause the IEEE to be informed) of the identity of any other holders of such potential Essential Patent Claims (that is, third parties that are not affiliated with the participant, with the participant s employer, or with anyone else that the participant is from or otherwise represents) The above does not apply if the patent claim is already the subject of an Accepted Letter of Assurance that applies to the proposed standard(s) under consideration by this group Early identification of holders of potential Essential Patent Claims is strongly encouraged No duty to perform a patent search 3
privecsg-15-0005-00-ecsg Patent Related Links All participants should be familiar with their obligations under the IEEE-SA Policies & Procedures for standards development. Patent Policy is stated in these sources: IEEE-SA Standards Boards Bylaws http://standards.ieee.org/develop/policies/bylaws/sect6-7.html#6 IEEE-SA Standards Board Operations Manual http://standards.ieee.org/develop/policies/opman/sect6.html#6.3 Material about the patent policy is available at http://standards.ieee.org/about/sasb/patcom/materials.html If you have questions, contact the IEEE-SA Standards Board Patent Committee Administrator at patcom@ieee.org or visit http://standards.ieee.org/about/sasb/patcom/index.html This slide set is available at https://development.standards.ieee.org/myproject/Public/mytools/mob/slideset.ppt 4
privecsg-15-0005-00-ecsg Call for Potentially Essential Patents If anyone in this meeting is personally aware of the holder of any patent claims that are potentially essential to implementation of the proposed standard(s) under consideration by this group and that are not already the subject of an Accepted Letter of Assurance: Either speak up now or Provide the chair of this group with the identity of the holder(s) of any and all such claims as soon as possible or Cause an LOA to be submitted 5
privecsg-15-0005-00-ecsg Other Guidelines for IEEE WG Meetings All IEEE-SA standards meetings shall be conducted in compliance with all applicable laws, including antitrust and competition laws. Don t discuss the interpretation, validity, or essentiality of patents/patent claims. Don t discuss specific license rates, terms, or conditions. Relative costs, including licensing costs of essential patent claims, of different technical approaches may be discussed in standards development meetings. Technical considerations remain primary focus Don t discuss or engage in the fixing of product prices, allocation of customers, or division of sales markets. Don t discuss the status or substance of ongoing or threatened litigation. Don t be silent if inappropriate topics are discussed do formally object. --------------------------------------------------------------- See IEEE-SA Standards Board Operations Manual, clause 5.3.10 and Promoting Competition and Innovation: What You Need to Know about the IEEE Standards Association's Antitrust and Competition Policy for more details. 6

privecsg-15-0005-00-ecsg IEEE 802 Privacy Rec PAR/CSD Privacy Recommendation PAR/CSD proposal presented and discussed during Atlanta s interim meeting https://mentor.ieee.org/privecsg/dcn/15/privecsg-15-0004-01-0000-privacy- recommendation-par-csd-proposal.pptx Currently planning to pre-circulate PAR as an 802.1 WG project proposal Deadline for consideration at March plenary is this Friday, March 6, 2015 11
privecsg-15-0005-00-ecsg MAC Randomization Experiment Preliminary results from trial at IETF 91 meeting presented in Atlanta Carlos J. Bernardos (University Carlos III of Madrid) Planning to repeat the trial at both upcoming IEEE 802 and IETF meetings IEEE 802 Plenary, Berlin, Germany, 8-13 March IETF 92 meeting, Dallas, TX, USA, 23-27 March 12
privecsg-15-0005-00-ecsg Trial setup WLAN address randomization scripts developed and provided for 3 different OSes: Microsoft Windows (tested on Windows 7) Apple Mac OS X (tested on Version 10.10, alias Yosemite) GNU Linux (tested on Debian testing/unstable, Ubuntu 13.10, and Fedora 20) Probes on DHCP and wireless network infrastructure https://www.ietf.org/registration/MeetingWiki/wiki/91privacy 13
privecsg-15-0005-00-ecsg Participants statistics Participation increased significantly throughout the week Around 3x at the end of the week (Mon-Thu) OS distribution: 7% Windows 40% Mac OS X 53% Linux 14
privecsg-15-0005-00-ecsg DHCP logs 685 Local MACs seen during the week 631 Local MACs were seen on the trial s WLAN network 125 Local MACs were also seen on regular IETF WLAN networks Estimating between 50 and 100 people participated in the trial Results based on the number of non-Local MAC seen on the trial s WLAN and other metrics (e.g., # different IP addresses allocated and DHCP hostnames provided) Method for better keeping track the number of participants should be provided in the future (e.g., use of IEEE 802.1X access setup) 15
privecsg-15-0005-00-ecsg Experiment's next steps Preparing a wish list with IETF NOC and SG members Logged information: working on potential additional logs that would help getting more precise information Increased frequency poll of logs at the routers (netdisco) Decrease DHCP lease time for Local MACs Access setup: use IEEE 802.1X to easily track participation Make a more detailed study of collision effects under different scenarios Need to increase participation Preparing address randomization tools for more platforms/OSes, including mobile ones (e.g. Android) 16
