To learn more about WPA please see Chapter 2. 4) WPA-PSK
WPA-PSK is a compromise between WPA and WEP. Like WEP, it uses a pre-shared key that every user of the network must have in order to be able to send and receive data. Like WPA, it uses either TKIP or AES, which improve greatly over the encryption found in WEP. We recommend you use WPA or WPA-PSK whenever possible.
