2 doc.: IEEE 802.11-09/1147r1 Submission November 2009 David Halasz, AclaraSlide 2 Abstract The path selection protocol has similar security concerns of path messages in AODV. Since the path selection messages use Multihop Action frames, the Multihop Action frames should be protected with IEEE 802.11w mechanisms. This will protect path messages on a link- to-link basis and not end-to-end. As of 802.11s draft 3.04, this presentation has already been addressed with the exception of updating the PICS.

3 doc.: IEEE 802.11-09/1147r1 Submission From RFC3561 – AODV 11 Security Considerations “… Route protocols, however, are prime targets for impersonation attacks. … … However, when the network membership is known and there is a danger of such attacks, AODV control messages must be protected by use of authentication techniques, such as those involving generation of unforgeable and cryptographically strong message digests or digital signatures. …” November 2009 David Halasz, AclaraSlide 3

5 doc.: IEEE 802.11-09/1147r1 Submission Areas that need attention from IEEE 802.11w Clause 8.3.4 The Broadcast/Multicast Integrity Protocol –CCMP issue doesn’t apply since not encrypting payload. Clause 7.3.1.11 Action field –Add “Robust” column to 802.11s draft table 7-24 Already modified on D3.04 November 2009 David Halasz, AclaraSlide 5
