Network Authentication

Since there is no precise bound in wireless

LANs, the WLAN users need to implement

certain mechanism to provide security solution.

The Authentication policies in this tab provide

protection of different levels such as Open,

Shared, WPA-PSK, WPA, WPA2 and WPA2-

PSK.

Open

- Select this option to make the network operate on Open System mode,

which use no authentication algorithm. Open stations and APs can authenticate

with each other without checking any WEP Key, even if there is.

Shared

- Select this option to make the network operate on Shared key mode.

In a Share Key Authentication system, four-step exchange of frames is required

to validate that the station is using the same WEP Key as the access point.

WPA-PSK / WPA2-PSK

- Select this option to enable WPA Pre-Shared Key

under Infrastructure mode. It enables communication between your client and

APs using WPA-PSK/WPA2-PSK encryption mode.

WPA / WPA2

- The network is operating in IEEE 802.1x authentication mode.

This mode is for environments with RADIUS (Remote Access Dial-in User

Service). In a RADIUS environment, ve Extensible Authentication Protocol

(EAP) are supported, including PEAP, TLS/Smart Card, TTLS, LEAP and

Md5-Challenge.

Cong - Encryption

This page enables you to congure the Wireless LAN Adapter encryption

settings. For data condentiality in a wireless environment, IEEE 802.11

species a Wired Equivalent Privacy (WEP) algorithm to offer transmission

privacy. The WEP uses keys to encrypt and decrypt data packets. The

encryption process can scramble frame bits to avoid disclosure to others. The

WPA/WPA2 is improved security system for 802.11 which are developed to

overcome the weakness of the WEP protocol.
