Wireless LAN(IEEE 802.11)에서 인증시간 단축을 위한 보안 메커니즘에 관한 연구
A Study on the Security Mechanism to Reduce Authentication Time in Wireless LAN(IEEE 802.11)
Abstract
Both security enhancement in wireless and fast access for mobility are required to employ wireless LAN in ITS (Intelligent Transportation Systems). However, for the case of employing IEEE 802.11i security standard, it is known that the user authentication procedure of IEEE 802.1x and 4-way handshake procedure for stronger security enforcement may not be suitable for ITS due to its large delay. In this paper, we propose fast authentication method to resolve the above authentication delay problem, and verify its performance via simulation analysis.
