WPA-PSK
WPA is a subset of technologies taken from the upcoming 802.11i standard. It
consists of 2 modes:
WPA Personal (WPA-PSK) for residential use.
WPA Enterprise for business use. Where the authentication is done by a special
server.
The SpeedTouch™ uses WPA-PSK which has 3 improvements regarding to WEP:
Authentication via a 4-way handshake to check whether the Pre Shared Keys
(PSKs) are the same.
Stronger encryption types:
Temporal Key Integrity Protocol (TKIP) (default): In stead 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.
To enable level2 - WPA-PSK:
1
Select Security Level 2 - WPA-PSK (WPA Personal).
2
In the WPA passphrase box, type a passphrase (aka Pre-shared key) of your
choice. The passphrase must consist of 8 to 64 characters.
3
In the Encryption list, click select the desired Encryption method (either TKIP or
AES).
4
Optionally select the rekeying interval.
5
Click Apply to immediately apply your changes.
It is recommended to choose TKIP because AES is not implemented in
the most clients but AES is implemented in the SpeedTouch™ because
it will be the future security standard.
