SMS(Short Message Service) based Secure Authentication and Accounting Mechanism in Wireless Network

The number of wireless public network user is increasing rapidly. Security problem for user authentication is risen on existing wireless network such as 802.11 based Wireless LAN. As a solution, 802.1x (EAP-MD5, EAP-TLS, EAP-TTLS), X.509, protocol or security system was developed by effective disposal plan of this problem. In this study, we overview main problem of existing EAP-MD5 authentication mechanism and propose a SMS based secure authentication mechanism for providing security enhanced wireless network.
