Configuring WPA/WPA2 using TKIP
6
The New Security Policy screen displays with no authentication or encryption options selected.
3. Select the KeyGuard radio button.
The KeyGuard Settings field displays within the New Security Policy screen.
4. Ensure the Name of the security policy entered suits the intended configuration or function of
the policy.
5. Configure the KeyGuard Settings field as required to define the Pass Key used to generate the
WEP keys used with the KeyGuard algorithm. These keys must be the same between the
access point and its Client to encrypt packets between the two devices.
Default (hexadecimal) keys for KeyGuard include:
6. Select the Allow WEP128 Clients checkbox (from within the KeyGuard Mixed Mode field) to
enable WEP128 clients to associate with an access point’s KeyGuard supported WLAN. The
WEP128 clients must use the same keys as the KeyGuard clients to interoperate within the
access point’s KeyGuard supported WLAN.
7. Click the Apply button to save any changes made within the KeyGuard Setting field of the New
Security Policy screen.
8. Click the Cancel button to undo any changes made within the KeyGuard Setting field and
return to the WLAN screen. This reverts all settings to the last saved configuration.
Configuring WPA/WPA2 using TKIP
Wi-Fi Protected Access (WPA) is a robust encryption scheme specified in the IEEE Wireless Fidelity
(Wi-Fi) standard, 802.11i. WPA provides more sophisticated data encryption than WEP. WPA is
designed for corporate networks and small-business environments where more wireless traffic
allows quicker discovery of encryption keys by an unauthorized person.
The encryption method is Temporal Key Integrity Protocol (TKIP). TKIP addresses WEP’s
weaknesses with a re-keying mechanism, a per-packet mixing function, a message integrity check,
and an extended initialization vector.
Pass Key Specify a 4 to 32 character pass key and click the Generate
button. The pass key can be any alphanumeric string. The
Mobility 5181 Access Point , other proprietary routers, 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.
Keys #1-4 Use the Key #1-4 areas to specify key numbers. The key can be
either a hexadecimal or ASCII depending on which option is
selected from the drop-down menu. The keys are 26 hexadecimal
characters in length or 13 ASCII characters. Select one of these
keys for activation by clicking its radio button.
