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:

1

Select Use WPA-PSK Encryption.

2

In 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.

3

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

4

Click Apply to immediately apply your changes.

5

Configure your wireless client(s) with the same settings.

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 87

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.
