P-334WH User's Guide
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.

WPA(2)-PSK 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.
