Config - Encryption

This page enables you to configure the Wireless LAN Adapter encryption
settings. For data confidentiality in a wireless environment, IEEE 802.11
specifies 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.
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-Personal,
WPA2-Personal, WPA-Enterprise, and
WPA2-Enterprise.
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-Personal/ WPA2-Personal - Select this option to enable WPA Pre-
Shared Key under Infrastructure mode. It enables communication between
your client and APs using WPA-Personal/WPA2-Personal encryption mode.
WPA-Enerprise/ WPA2-Enterprise - 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, three Extensible
Authentication Protocol (EAP) are supported, including PEAP, EPA/TLS, and
LEAP.
