WPA/WPA2-TKIP

Configuring WLAN Security

Wi-Fi Protected Access (WPA) is an 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, however TKIP also has vulnerabilities.

Wi-Fi Protected Access 2 (WPA2) is an enhanced version of WPA. WPA2 uses the Advanced
Encryption Standard
(AES) instead of TKIP. AES supports 128-bit, 192-bit and 256-bit keys.
WPA/WPA2 also provide strong user authentication based on 802.1x EAP.

To configure WPA/WPA2 encryption on a WLAN:

1. Select the Configuration tab from the Web UI.

2. Select Wireless.

3. Select Wireless LANs to display a high level display of existing WLANs.

4. Select the Add button to create an additional WLAN or select an existing WLAN and select Edit

to modify its properties.

5. Select Security.

6. Select the WPA/WPA2-TKIP radio button from within the Select Encryption field.

The screen populates with the parameters required to define a WPA/WPA2-TKIP configuration for
the WLAN.
