What is WPA Functionality?

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification

draft. Key differences between WAP and WEP are user authentication and improved

data encryption WAP applies IEEE 802.1x Extensible Authentication Protocol (EAP)

to authenticate wireless clients using an external RADIUS database. You can not use

the 662's local user database for WPA authentication purpose since the local user

database uses MD5 EAP which can not to generate keys.

WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP),

Message Integrity Check and IEEE 802.1x. Temporal Key Integrity Protocol uses

128-bits keys that are dynamically generated and distributed by the authentication

server. It includes a per-packet key mixing function, a Message Integrity Check (MIC)
