| Summary: | 碩士 === 國立交通大學 === 資訊科學系 === 91 === Security and authentication are the most important topics in wireless networks. In recent years, IEEE 802.1x, proposed by IEEE, provides a proper authentication architecture. It has been used in wireless local area networks widely. In IEEE 802.1x architecture, authentication server is responsible to authenticate users and manage users’ information. Authenticator is responsible to transfer the authentication messages between users and authentication server. In general, authenticator and authentication server use the RADIUS protocol to communicate with each other. However, the existing softwares and devices that implement IEEE 802.1x and RADIUS protocol work over IPv4 networks. Up to now, we didn’t find authentication systems based on IEEE 802.1x and RADIUS protocol run over IPv6 networks. In this thesis, we implement an IPv6 authentication system based on IEEE 802.1x and RADIUS protocol to provide authentication to wireless LAN users. A prototype is presented to demonstrate that our approaches are feasible.
