3.6 Authentication
When authenticating a user, the base station uses a third-party RADIUS or Diameter server
known as an AAA (Authentication, Authorization and Accounting) server to authenticate the
mobile or subscriber stations.
WiMAX uses PKM (Privacy Key Management) for authentication between the mobile or
subscriber station and the base station, and supports EAP (Extensible Authentication Protocol)
between the mobile or subscriber station, the base station, and the AAA server.
The following figure shows a base station using an AAA server to authenticate mobile station
MS , allowing it to access the Internet.

the mobile station, the base station and the AAA server. See the WiMAX security appendix for
