Enhanced WEP: A New Efficient Solution to WEP Threats

Free registration required

Executive Summary

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 this paper the authors' 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. The 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, the solution requires neither hardware add-on nor replacement, but merely software updates.
