  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: Ft. Lauderdale 802.11i/802.15 Liaison Report. Date Submitted: 17 January, 2003 Source: Daniel V.

  2. Post LB 52 • LB52 concluded before Ft. Lauderdale • Yes: 76.28%, No: 23.72%, Abs: 7.12% • Yes: 209, No: 65, Abs: 21 • Total voting members: 321 • Total returned: 295 • Total returned %: 91.90% • 2,074 comments received • 1,262 technical Daniel V. Bailey, NTRU

  3. Comment Resolution • 11-03-118r1 eliminates a large number of comments by removing CCM spec from TGi draft and referring to the NIST CCM submission. • It’s a publicly-available submission, not a standard. • 15.3 and 15.4 may want to consider this to simplify their specs. • An IETF Internet-Draft is coming soon Daniel V. Bailey, NTRU

  4. Major Issues • OCB removed! CCM the only approved AES mode • MSDU (payload) vs.MPDU (payload+header) level (see 11-03-122r0) • TKIP operates on MSDUs, while CCM operates on MPDUs • Makes it hard to do CCM in host software since fields may not be available • but MSDU-only doesn’t protect MAC headers Daniel V. Bailey, NTRU

  5. Major Issues • Roaming and secure handoff too slow for uninterrupted VoIP (11-03-084r1) • STA moving from AP to AP securely • Key management involves 3 state machines: 802.11 authentication, 802.1x port control, and the EAP (authentication) method • They’re not currently well-synchronized • (11-03-079r0) Daniel V. Bailey, NTRU

  6. Seattle Adhoc • February 17-21, 2003 • For comment resolution Daniel V. Bailey, NTRU
