Configuring WEP 128 / KeyGuard
WEP 128 provides a more robust encryption algorithm that WEP 64 by requiring a longer key length
and pass key. Thus, making it harder to hack through the replication of WEP keys. WEP 128 may be
all that a small-business user needs for the simple encryption of wireless data.
KeyGuard is a proprietary encryption method developed by Brocade Technologies. KeyGuard is
Brocade's enhancement to WEP encryption, and was developed before the finalization of WPA-TKIP.
This encryption implementation is based on the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11i.
To configure WEP 128 or KeyGuard:
1. Select Network > Wireless LANs from the main menu tree.
2. Select an existing WLAN from those displayed within the Configuration tab and click the Edit
3. Select either the WEP 128 or KeyGuard button from within the Encryption field.
4. Click the Config button to the right of the WEP 128 and KeyGuard checkboxes.
5. Specify a 4 to 32 character Pass Key and click the Generate button.
6. Use the Key #1-4 areas to specify key numbers.

button.
A WLAN screen displays with the WLAN's existing configuration. Refer to the Authentication
and Encryption columns to assess the WLAN's existing security configuration.
The WEP 128 / KeyGuard screen displays.
The pass key can be any alphanumeric string. The controller and Brocade Clients use the
algorithm to convert an ASCII string to the same hexadecimal number. Clients without Brocade
adapters need to use WEP keys manually configured as hexadecimal numbers.
The key can be either a hexadecimal or ASCII. The keys are 26 hexadecimal characters in
length or 13 ASCII characters. Select one of these keys for activation by clicking its radio
button.
