Figure 90   WPA(2) with RADIUS Application Example

A WPA(2)-PSK application looks as follows.

1 First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key 

(PSK) must consist of between 8 and 63 ASCII characters or 64 hexadecimal characters 
(including spaces and symbols).

2 The AP checks each wireless client's password and (only) allows it to join the network if 

the password matches.

3 The AP and wireless clients use the pre-shared key to generate a common PMK 

(Pairwise Master Key).

4 The AP and wireless clients use the TKIP or AES encryption process to encrypt data 

exchanged between them.
