IEEE 802.1x Access Control

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 ZyAIR'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) named Michael, an extend initialization vector (IV) with sequencing rules and a re-keying mechanism.

If you do not have an external RADIUS, server, you should use WPA-PSK (WPA Pre-Share Key) that only requires a single (identical) password entered into each

access point, wireless gateway and wireless client. As long as the password match, a client will be granted access to a WLAN.

Here comes WPA-PSK Application example for your reference.
