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-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, five Extensible Authentication Protocol
(EAP) are supported, including PEAP, TLS/Smart Card, TTLS, LEAP and
Md5-Challenge.
