WPA(2)-PSK Application Example
A WPA(2)-PSK application looks as follows.
First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist
1
of between 8 and 63 ASCII characters or 64 hexadecimal characters (including spaces and symbols).
The AP checks each wireless client's password and allows it to join the network only if the password
2
matches.
The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over
3
the network, but is derived from the PSK and the SSID.
The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged
4
in a handshake to create temporal encryption keys. They use these keys to encrypt data exchanged
between them.
