Authentication Types
The IEEE 802.1x standard provides a general authentication framework for 802 LANs
and specifies an extensible authentication protocol (EAP) to enable LAN transport for
many different types of authentication protocols. A WAN client initiates an authorization
request to the access point, which authenticates the client to an Extensible
Authentication Protocol (EAP) compliant RADIUS server. This RADIUS server may
authenticate either the user (via passwords) or the machine (by MAC address). 802.1x
authentication is independent of the 802.11 authentication process. The 802.1x standard
provides an authentication framework. There are different 802.1x authentication types,
each providing a different approach to authentication employing the same protocol and
framework for communication between a client and an access point. In most protocols,
upon the completion of the 802.1x authentication process, the supplicant receives a key
that it uses for data encryption.
