PPP Authentication Protocols (PAP and CHAP)
All asynchronous and synchronous PPP links are configurable to use either PAP or 
CHAP PPP authentication protocols. PAP establishes peer identity using a 2-way 
handshake that is done only upon initial link establishment. CHAP performs a 3-way 
handshake upon initial link establishment, then proceeds to verify the link with 3-way 
handshakes at random intervals. CHAP also encrypts the user’s password over the 
PPP link to provide added security.
