Performance Evaluation of Authentication Protocols for IEEE 802.11 Standard

With the growing popularity of IEEE 802.11 WLAN Standards, securing authentication process between client, authenticator and authentication server has become of utmost importance. For securing the authentication process, Extensible Authentication Protocol (EAP) supports an open architecture allowing multiple EAP authentication methods to be used. EAP re-authentication protocol provides a consistent, method-independent and low-latency re-authentication mechanism for authentication in 802.11 wireless networks. Mechanisms of authentication usually exist above the physical layer. In few cases utilizing spread-spectrum technique, authentication process may exist at physical layer but incurring an additional cost on bandwidth.
