February 11 - 12, 2002, CMC, Santa Barbara, California

At the February meeting, the group worked towards ideas on preparing the TGi draft, so that it would be acceptable for letter ballot. The first thing the group did was go through a packet flow. The packet flow followed an asociation and authentication, from probe request on through to 802.1X authentication and establishment of keying material. An outline for a new clause 8 was started. The intent of the new clause 8, was to make editorial changes that will make the text more readable. The desire is to follow up on a new clause 8, and make a submission in the March meeting. The intent would then be to vote on this submission as a replacement to the existing clause 8.

January 21 - 25, 2002, Wyndham Anatole, Dallas, Texas

At the January meeting, the group worked towards updating the draft for TKIP and re-keying.


Major motions

- AES
- Adopt AES w/CNTR mode & CBC-MAC: FAILED
- Other
- Adopt 802.1X re-keying text, from documet 01/667, as informational document: PASSED
- Send letter to IESG/IETF 02/040: PASSED
- Misc.
