WPA-PSK (Wi-Fi Protected Access-Pre-Shared Key)
WPA-PSK stands for Wi-Fi Protected Access-Pre-Shared Key; basically it is
an authentication mechanism in which users provide some form of
credentials to verify that they should be allowed access to a network.
The encryption mechanisms for WPA and WPA-PSK are the same. The only
difference is that the authentication in WPA-PSK is reduced to a simple
password, instead of user-specific credentials.
