2.3.7. LEAP Authentication
LEAP (Lightweight Extensible Authentication Protocol) also known as Cisco-
Wireless 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 variety of authentication protocols
to be used. It passes through the exchange of authentication messages, allowing
the authentication software stored in a server to interact with its counterpart in the
client
