WPA-PSK
Summit WM User Guide, Software Version 5.3
Explanation
Wi-Fi Protected Access with Pre-Shared Key, a special mode of WPA for
users without an enterprise authentication server. Instead, for
authentication, a Pre-Shared Key is used. The PSK is a shared secret
(passphrase) that must be entered in both the Wireless AP or router and
the WPA clients.
This preshared key should be a random sequence of characters at least 20
characters long or hexadecimal digits (numbers 0-9 and letters A-F) at least
24 hexadecimal digits long. After the initial shared secret, the Temporal
Key Integrity Protocol (TKIP) handles the encryption and automatic
rekeying.
