2.2.5 WPA with RADIUS Application Example

You need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared

secret. A WPA application example with an external RADIUS server looks as follows. "A" is the RADIUS

server. "DS" is the distribution system.

1. The AP passes the wireless client's authentication request to the RADIUS server.

2. The RADIUS server then checks the user's identification against its database and grants or denies

network access accordingly.

3. The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key

hierarchy and management system, using the pair-wise key to dynamically generate unique data

encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the

wireless clients.
