Using WPA Security
Wi-Fi Protected Access (WPA) is a strongly enhanced,
interoperable Wi-Fi security that addresses many of the
vulnerabilities of Wired Equivalent Privacy (WEP). Instead
of WEP, WPA uses Temporal Key Integrity Protocol (TKIP)
for its data encryption method.
Currently, WPA satisfies some of the requirements in the IEEE
802.11i draft standard. When the standard is finalized, WPA
will maintain forward compatibility.
WPA runs in 802.1x (Enterprise) mode or PSK (Pre-Shared
Key) mode:
• In Enterprise mode, WPA provides user authentication using
802.1x and the Extensible Authentication Protocol (EAP).
That is, an authentication server (such as a RADIUS server)
must authenticate each device before the device can
communicate with the wireless network.
• In PSK mode, WPA provides user authentication using a
shared key between the authenticator and the CN2G. WPA-
PSK is a good solution for small offices or home offices that
do not want to use an authentication server.
To use WPA security, you need:
• an authentication server (Enterprise mode only).
Note: You can also use a MobileLAN access WA2XG
product as an authentication server. For help, see the
MobileLAN access WA2XG System Manual (P/N 074921).
• user and root certificates (if you plan to use TLS for
authentication)
• an access point with an 802.11b/g radio that supports WPA.
