G-3000H User’s Guide

The following figure shows an overview of authentication when you specify a RADIUS server on your access point.

Figure 27 EAP Authentication

The details below provide a general description of how IEEE 802.1x EAP authentication works. For an example list of EAP-MD5 authentication steps, see the IEEE 802.1x appendix.

1The wireless station sends a “start” message to the ZyAIR.

2The ZyAIR sends a “request identity” message to the wireless station for identity information.

3The wireless station replies with identity information, including username and password.

4The RADIUS server checks the user information against its user profile database and determines whether or not to authenticate the wireless station.

6.5Dynamic WEP Key Exchange

The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed.

To use Dynamic WEP, enable and configure the RADIUS server and enable one of the Dynamic WEP Security Modes in the Security screen. Ensure that the wireless station’s EAP type is configured to one of the following:

•EAP-TLS

•EAP-TTLS

•PEAP

Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange.

6.6 Introduction to WPA

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. Key differences between WPA and WEP are user authentication and improved data encryption.
