Hey Jaideep,

as Sven mentioned correctly, using the WPA sequence numbers in

WPA_NONE should be ignored. Some drivers (like madwifi) have to be teached to >> do that. Sequence numbers do not make much sense in Ad-Hoc anyway, as there is no central management for these sequence numbers. Of course, you >> lack some security features like detecting replay attacks or changing session keys which you have in master/station WPA.

Hey Simon,

I understand. So does that mean all the city-wide mesh deployments we are seeing are susceptible to reply attack etc ? Will try to follow on Jouni's suggestion of fixing nl driver layer for 4-way handshake, GTK mgmt to see if I can contribute to solving this problem.

Thanks for your help. Jaideep
