PCE-N53 Wireless Dual-band Card Manual

Configuration - 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.

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.
