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 allows it to join the network only if

the password matches.

3 The AP and wireless clients generate a common PMK (Pairwise Master Key). The key

itself is not sent over the network, but is derived from the PSK and the SSID.

4 The AP and wireless clients use the TKIP or AES encryption process, the PMK and

information exchanged in a handshake to create temporal encryption keys. They use

these keys to encrypt data exchanged between them.
