Avaya AP-4, AP-6, AP-5 manual Wi-Fi Protected Access WPA

Security

Upon receiving a reply EAP packet from the RADIUS, the message is typically forwarded to the client, after translating it back to the EAPOL format. Negotiations take place between the client and the RADIUS server. After the client has been successfully authenticated, the client receives an Encryption Key from the AP (if the EAP type supports automatic key distribution). The client uses this key to encrypt data after it has been authenticated.

For 802.11a and 802.11b/g clients that communicate with an AP, each client receives its own unique encryption key; this is known as Per User Per Session Encryption Keys.

Wi-Fi Protected Access (WPA)

Wi-Fi Protected Access (WPA) is a security standard designed by the Wi-Fi Alliance in conjunction with the Institute of Electrical and Electronics Engineers (IEEE). WPA is a sub-set of the forthcoming IEEE 802.11i security standard, currently in draft form. (IEEE 802.11i is also referred to as “WPA2” and will be available in 2004.)

NOTE:

For Single-radio APs: WPA is available for the AP-6 (or APs that have an 802.11a/b/g or 802.11b/g upgrade kit). WPA is NOT available for the AP-5 or AP-4. Note that while you can select WPA on AP-5 units, WPA is not supported for the AP-5 unless you have installed an 802.11a/b/g upgrade kit.
