초록

The importance of security in WLAN(Wireless LAN) service is very critical, so IEEE organization has made the IEEE 802.1x standard. The IEEE 802.1x standard uses the EAP as authentication protocol which requires AAA(Authentication, authorization, and Accounting) server for authentication & accounting. for the reliable and scalable AAA service, the Diameter protocol has more advanced characteristics than existing radius protocol. So the Diameter protocol can be used for WLAN service provider who has large scale WLAN system and a large number of subscriber. This paper proposes the design of Diameter AAA server for the authentication and accounting of WLAN system which is adopting IEEE 802.1x standard.
