Secure authentication and accounting mechanism on WLAN with interaction of mobile message service

Abstract

In a wireless network that uses 802.IX Port Access Control, the wireless station plays the role of the Remote User and the wireless AP plays the role of the Network Access Server (NAS). However, Security problem for user authentication has been increased on existing IEEE 802.11 wireless network. However, brute force dictionary attack can be launched against the shared secret on existing IEEE802.1× (EAP-MD5, EAP-TLS, EAP-TTLS) protocols or security systems. Therefore, we overview main problem on existing EAP-MD5 authentication mechanism on Wireless LAN and propose a SMS(Short Message Service) based secure authentication and accounting mechanism for providing security enhanced wireless network transactions against those attacks. © Springer-Verlag Berlin Heidelberg 2007.
