Overview
802.1x authentication is independent of the 802.11 authentication process. The 802.1x
standard provides a framework for various authentication and key-management
protocols. There are different 802.1x authentication types, each providing a different
approach to authentication but all employing the same 802.1x 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. Refer to
802.1x and Data encryption for more information.
With 802.1x authentication, an authentication method is used between the client and a
