Technology Review
CHAP and PAP are two authentication methods that enjoy widespread support. Both methods are included
in the AOS and are easily configured.
The authentication method set up on the local router can be different from that on the peer.
Also, just because one router requires authentication from its peer does not mean it also
has to authenticate itself to the peer.
Defining PAP
The Password Authentication Protocol (PAP) is used to verify that the PPP peer is a permitted device by
checking a username and password configured on the peer. The username and password are both sent
unencrypted across the connecting private circuit.
PAP requires two-way message passing. First, the router that is required to be authenticated (say the peer)
sends an authentication request with its username and password to the router requiring authentication
(say the local router). The local router then looks up the username and password in the username
database within the PPP interface, and if they match sends an authentication acknowledge back to the
peer.
