Figure 31 WPA - PSK Authentication

5.5.2 WPA with RADIUS Application Example

You need the IP address, port number (default is 1812) and shared secret of a RADIUS server. A WPA application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system (wired link to the LAN).

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

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

3The 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 transmitted between the AP and the wireless clients
