EAP provides username/password-based authentication between a wireless client and a
RADIUS server. LEAP is one of several protocols used with the IEEE 802.1X
standard for LAN port access control. LEAP also delivers a session key to the
authenticated station, so that future frames can be encrypted with a key that is different
than keys used by others sessions. Dynamic key delivery eliminates one big
vulnerability; static encryption keys that are shared by all stations in the WLAN. EAP
(Extensible Authentication Protocol) is an extension to the PPP protocol that enables a

authentication messages, allowing the authentication software stored in a server to
interact with its counterpart in the client
