Technology Review
CHAP and PAP are two authentication methods that enjoy widespread support. Both methods are included
in 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 PAP is used to verify that the PPP peer is a permitted device by checking a user name and password
configured on the peer. The user name and password are both sent unencrypted across the connecting
private circuit.
PAP requires a two-way message passing. First, the router that is required to be authenticated (for
example, the peer) sends an authentication request with its user name and password to the router
requiring authentication (for example, the local router). The local router then looks up the user name and
password in the user name database within the PPP interface and, if they match, sends an authentication
acknowledge back to the peer.
