Figure 28 WPA - PSK Authentication
7.5.2 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).
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
transmitted between the AP and the wireless clients
