WPA(2)-PSK Application Example
A WPA(2)-PSK application looks as follows.
1 First enter identical passwords into the AP and all WiFi clients. The Pre-Shared Key (PSK) must consist of
between 8 to 63 alphanumeric (0-9, a-z, A-Z) and special characters, including spaces.
2 The AP checks each WiFi client's password and allows it to join the network only if the password
matches.
3 The AP and WiFi 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 WiFi 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.
