Theoretical MAC Layer Protection of 802.11 Management Frames

Monday, June 13th, 2011

After a large amount of pondering how to “hack” the hackers, I came up with an idea that could theoretically work against packet injection. This would involve re-writing drivers though.

In this paper, a new defensive strategy for management frames is described. Management frames in 802.11 are not encrypted as of the writing of this document. The IEEE[i] 802.11w amendment is said to address this issue, but has not. The method explained in this document protects the management frames at the MAC level. It does not, however, resolve the cryptographic-key management issues apparent in WPA/WPA2.

Enjoy! :)
