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.
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 the access point:
1 Select Network Configuration > Wireless > Security from the access point menu tree.
If security policies supporting WPA-TKIP exist, they appear within the Security Configuration screen.
These existing policies can be used as is, or their properties edited by clicking the Edit button. To
configure a new security policy supporting WPA-TKIP, continue to step 2.
2 Click the Create button to configure a new policy supporting WPA-TKIP.
The New Security Policy screen displays with no authentication or encryption options selected.
3 Select the WPA/WPA2 TKIP radio button.
The WPA/TKIP 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.
