Config - Encryption

The Encryption page allows you to set

up the encryption settings for your WLAN

card. For data confidentiality in a wireless

environment, IEEE 802.11 specifies a Wired

Equivalent Privacy (WEP) algorithm to

offer transmission privacy similar to wired

network. WEP uses keys to encrypt data

packets sent and decrypt data packets

received. The encryption process can

scramble frame bits to avoid disclosure to others. Wi-Fi Protected Access (WPA) is

an improved security system for 802.11 that encrypts data sent over radio waves.

WPA is developed to overcome the weakness of the WEP protocol.
Network Authentication - Set up authentication for your WLAN card. Options are:

Open - Sets the network operating in the Open System mode that disables

authentication protection for the network or use the WEP encryption for the

network.

Shared - Sets the network operating in the Shared Key mode that uses the

WEP encryption for your network.

WPA-PSK/WPA2-PSK - Use the WPA Pre-Shared Key/WPA2 Pre-Shared Key

in the Infrastructure mode for authentication.

WPA/WPA2 - Enables the IEEE 802.1x authentication mode. This mode is for

environments with Remote Access Dial-in User Service (Radius). In a RADIUS

environment, various Extensible Authentication Protocol (EAP) are supported,

including PEAP, TLS/Smart Card, TTLS, and LEAP.

Data Encryption - In the Open and Shared authentication modes, options are:

Disabled and WEP.

Disabled - Disables the encryption protection for your WLAN card.

WEP - Encrypts the data before it is transmitted over the air. You can

communicate with wireless devices that use the same WEP keys.

In the WPA-PSK and WPA2-PSK authentication modes, options are: Temporal Key

Integrity Protocol (TKIP) and Advanced Encryption Standard (AES).

TKIP - Dynamically generates unique keys to encrypt data packet.

AES - Offers stronger protection and increases the complexity of wireless

encryption. It is a symmetric 128-bit block encryption method that works

simultaneously on multiple network layers.
