The SpeedTouch™ supports WPA-PSK, which offers three advantages over WEP:

Authentication via a 4-way handshake to check whether the Pre-Shared Keys (PSKs) are identical.

Stronger encryption types:

Temporal Key Integrity Protocol (TKIP) (default): Instead of using a fixed WEP key, TKIP uses in pairs temporary session keys which are derived from the PSK during the 4-way handshake. For each packet it uses a different key. TKIP also provides a message integrity check (MIC) and a rekeying mechanism (in seconds).

Advanced Encryption Standard (AES): State-of-the-art encryption; can only be used if all wireless devices in your WLAN support AES.

Message Integrity Check (MIC). Which is a strong mathematical function in which the recipient and transmitter each compute and compare the MIC. If they don't match it is assumed that a third person has been trying to read the data.

Proceed as follows to enable WPA-PSK:

1Select Use WPA-PSK Encryption.

2In the WPA-PSK Encryption Key box, type a pass phrase (also known as Pre- shared key) of your choice. The pass phrase must consist of 8 to 63 ASCII characters or 64 HEX digits.

3In the WPA-PSK Version list, click the desired WPA-PSK version.

Depending on the WPA-PSK version you choose, one of the following WPA-PSK encryption will be set automatically:

WPA: TKIP

WPA2: AES

WPA+WPA2: TKIP+AES

AES is not yet implemented in most clients but it is in the

SpeedTouch™ because it will be the future security standard.
