WPA-PSK Wifi Protected Access
WPA (Wifi Protected Access) can use only the TKIP (Temporal Key Integrity Protocol) encryption cipher.
PSK (Pre-Shared Key) is a client authentication method that generates unique encryption keys based on the alphanumeric passphrase (up to 133 characters) and the network name (SSID).
For improved security it is better to use WPA2-PSK instead of WPA-PSK if your device supports it.
