WPA (Wi-Fi Protected Access) is a security protocol for Wireless Local Area Networks
(WLAN). WPA uses a sophisticated key hierarchy that generates new encryption
keys each time a mobile device establishes itself with an access point. Protocols in-
cluding 802.1X, EAP and RADIUS are used for strong authentication. Like WEP, keys
can still be entered manually (preshared keys); however, using a RADIUS authenti-
cation server provides automatic key generation and enterprise-wide authentication.
