802.11w is the latest entry into the 802.11 alphabet soup. .11w plans to extend security for wireless from just the payload part of the packet, to the managment frames as well. Currently thse frames are sent in the clear. These improvments should help prevent information about the network being leaked to an attacker. 802.11w also proposes to solve another problem with unauthenticated managment frames; the deauth DoS attack. By using one time passwords for deauth/dissassociate frames, the client and AP have the ability to tell if a deauth is legit or not.
