Table 2-6 WPA-PSK Authentication

 

 

FIELD

DESCRIPTION

 

 

Encryption Status

All unicast traffic is automatically encrypted by TKIP when WPA or WPA-PSK

 

Authentication is selected. See the section on Encryption for details about

 

Temporal Key Integrity Protocol (TKIP).

Passphrase

Type a Passphrase from 8 to 63 ASCII characters long. The Passphrase is case-

 

sensitive. You must use the same Passphrase for all wireless LAN adapters with

 

this feature in the same WLAN. For more information on Passphrase, see section

 

2.6.1.

2.6.4 Data Encryption with 802.1x

Select 802.1x from the Authentication drop-down list box to view the security configuration options.

802.1x Overview

The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication can be done using an external RADIUS server for an unlimited number of users.

EAP Authentication Overview

EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, the access point helps a wireless station and a RADIUS server perform authentication.

The type of authentication you use depends on the RADIUS server or the AP. The ZyAIR supports EAP-TLS, EAP-TTLS, LEAP and PEAP with RADIUS. Refer to the Types of EAP Authentication appendix for descriptions on the different types.

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.

♦The wireless station sends a “start” message to the AP.

♦The AP sends a “request identity” message to the wireless station for identity information.

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

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