WPA-PSK/WPA2-PSK Authentication

2.2.3 WPA and WPA2 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/WPA2 application example with an external RADIUS server looks as follows. “A” is the

RADIUS server. “DS” is the distribution system.

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

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

denies network access accordingly.

Step 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.
