Abstract
Since the IEEE 802.11 wireless LANs were known to have several critical weaknesses in the aspect of security, a lot of works have been done to reduce such weaknesses of the wireless LAN security, Among them IEEE 802.lli may be the ultimate long-term solution that requires new security platform with new wireless LAM products. However, it might not be the best solution for small organizations due to its high cost where the cost is a critical issue. This paper proposes FR-WEP, a light-weight key management for wireless LANs that can be used with small changes of the existing Products. FR-WEP is an extension to a lightweight key management, WEP'(9), which was proposed lately. It makes up for the weak points of WEP' by providing lightweight mutual authentication with both host keys and user keys, and seamless key-refresh for authenticated users with fast re-authentication. It would be a good alternative to the heavy standards for wireless LAN security, especially to small organizations hoping for better security.
