Enhanced WEP: a new solution to WEP threats
Résumé
With the rapidly increasing importance of wireless networks, there have been many recent proposals, dealing with the insecurity of the Wired Equivalent Privacy (WEP) protocol. In our paper, we have analyzed threats' origins, and proposed a new solution based upon the WEP, which achieves, in addition to security goals originally aimed at by WEP, another security service which is replay detection. Our premise is to permit deploying an efficient security mechanism on wireless networks, without reconsidering all the security architecture. Contrary to the standards WPA proposed by the Wi-Fi Alliance and IEEE 802.11i proposed by the Task Group I of IEEE 802.11, our solution requires neither hardware add-on nor replacement, but merely software updates.
