SpeedTouch™ Web Interface
128 bit, Alphanumeric:
The 104-bit Network key consists of 13 alphanumeric characters.

WPA-PSK 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.

Access control on the
SpeedTouch™
The following modes are available:
New stations are allowed (automatically):
All New stations can access the SpeedTouch™ WLAN.
New stations are allowed (via registration):
Only allowed stations in the Access Control List (ACL) have access. You can
add new stations via registration.
For more information, see “Allowing new wireless” on page 108
New stations are not allowed:
Only allowed stations in the Access Control List (ACL) have access.
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.
