USB-N66 WLAN Adapter User Manual

Configuration - Encryption

The Encryption page allows you to set up the encryption settings for your WLAN adapter. 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 adapter. 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-Personal/WPA2-Personal - Use the WPA Pre-Shared Key/WPA2 Pre-Shared Key in the Infrastructure mode for authentication.

•WPA/WPA2-Enterprise/WEP 802.1X - Set these authentication modes in the Infrastructure mode (needs to add a RADIUS server to confirm the user’s identity). Two Extensible Authentication Protocol (EAP) are supported In the RADIUS environment, including PEAP and TLS/Smart Card.

•Data Encryption - Encrypts the data before it is transmitted over the air.

In the Open and Shared authentication modes, options are Disabled and WEP.

•Disabled - Disables the encryption protection for your WLAN adapter.

•WEP - When you select this option, the cursor appears in the field for Key 1. Key in 10 hexadecimal digits (0~9, a~f, and A~F) for the 64-bit encryption.

In the WPA-PSKand WPA-Personal and WPA2-Personal 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
