CHAP - Challenge/Handshake Authentication Protocol

Challenge/Handshake Authentication Protocol is a system for determining if a user has the correct password without openly revealing that password. CHAP does not itself prevent unauthorized access; it merely identifies the remote end. The NAS (Network Access Server) application then determines whether that user is allowed access to the protected resources.
