Enhanced WEP: an efficient solution to WEP threats

Abstract

Security is a strong requirement for effective deployment of business wireless communication applications. Therefore, many proposals dealt with security holes in wired equivalent privacy protocol (WEP). In this paper, we analyze WEP security holes and we propose an improvement over WEP which achieves, in addition to its security goals, 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 802.11 proposed by the task group I of IEEE 802.11, our solution requires neither hardware add-on nor replacement, but merely software updates.
