Extensible Authentication Protocol (EAP)

Extensible authentication protocol (EAP) is an extensible framework and transport for other network access authentication protocols. The original dial-up Point-To-Point Protocol (PPP) provided only basic security by using Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP). EAP was added to support more-sophisticated authentication, particularly on wireless networks.
