Literature Review on EAP Methods

Extensible Authentication Protocol (EAP), defined in RFC 3748 [1], is a flexible authentication framework that has been frequently utilized in WLANs. For IEEE 802.11, WPA and WPA2 have utilized EAP as their authentication mechanisms, such as EAP-TLS, EAP-TTLS, and EAP-SIM. A network administrator can appropriately choose a desired authentication mechanism, called an EAP method. In this paper we have discussed different EAP methods & its implementation, application. There are different requirements of EAP methods defined in RFC 3748 which are partially or fully satisfied by these methods. These methods are widely used in authentication for wireless network. There are several vendor specific methods which are simpler and satisfy the requirements in RFC 3748.
