B3.2 WPA/WPA2
WPA/WPA2 (Wi-Fi Protected Access) is more secure than WEP. It uses a “Shared Key” which
allows the encryption keys to be regenerated at a specified interval. There are several encryption
options: TKIP, AES, TKIP-AES and additional setup for RADIUS is required in this method. The most
important features beyond WPA to become standardized through 802.11i/WPA2 are: pre-
authentication, which enables secure fast roaming without noticeable signal latency.
If WPA or WPA2 is used, the Wireless Stations and the Access Point must have the same security
settings.
B3.3 WPA-PSK/WPA2-PSK
WPA/WPA2 (Wi-Fi Protected Access using Pre-Shared Key) is recommended for users who are not
using a RADIUS server in a home environment and all their clients support WPA/WPA2. This
method provides a better security.
If WPA-PSK or WPA2-PSK is used, the Wireless Stations and the Access Point must have the same
security settings.

B3.4 802.1x
With 802.1x authentication, a wireless PC can join any network and receive any messages that are
not encrypted, however, additional setup for RADIUS to issue the WEP key dynamically will be
required.
RADIUS is an authentication, authorization, and accounting client-server protocol. The client is a
Network Access Server that desires to authenticate its links. The server is a server that has access
to a user database with authentication information.
