Link-layer protection in 802.11i WLANS with dummy authentication

Zhimin Yang, Adam C. Champion, Boxuan Gu, Xiaole Bai, Dong Xuan
2009 Proceedings of the second ACM conference on Wireless network security - WiSec '09  
We argue that regardless of the type of network under consideration, link-layer protection and data confidentiality are of great importance in wireless applications.  ...  In dummy authentication, we apply public-key cryptography's key-establishment technique to the 802.11 MAC protocol.  ...  The vulnerability of WPA-PSK with a weak key to dictionary attacks is not a design flaw of the standard. Still, in reality, most people use a simple password as a pre-shared secret.  ...
