Authorization involves granting access to network resources and services.
Before authorization to network resources can be granted, proper authentication must occur.
Some may provide for only one-way authentication, while others provide two-way authentication.
Mutual authentication not only requires that the authentication server validate the client credentials, but the supplicant must also authenticate the validity of the authentication server.
Authentication is the verification of user identity and credentials.
Extensible Authentication Protocol (EAP) is used to provide user authentication.
The access point and the client station now both have unique unicast keys that can be used.
A second static key exists on the access point known as the broadcast key.
A side benefit of EAP protocols that utilize mutual authentication is the generation and distribution of dynamic encryption keys.
Until now, you have learned about only static or preshared WEP keys.
