PEAP
Protected Extensible
Authentication Protocol is an IETF draft standard to authenticate wireless LAN clients
without requiring them to have certificates. In PEAP authentication, first the user
authenticates the authentication server, then the authentication server authenticates the
user. If the first phase is successful, the user is then authenticated over the SSL tunnel
created in phase one using EAP-Generic Token Card (EAP-GTC) or Microsoft Challenged
Handshake Protocol Version 2 (MSCHAP V2). (See also
EAP-TLS/EAP-TTLS.)
