Password Authentication Protocols
(PAP)
PAP provides a simple method for a remote node to establish its
identity using a
establishment phase is complete, a username and password pair
is repeatedly sent by the remote node across the link (in clear
text) until authentication
connection is terminated.
PAP supports bi-directional (two ways) and unidirectional (one
way) authentication. With unidirectional authentication, only the
side receiving the call (NAS) authenticates the remote side
(client). The remote client does not authenticate the server.
With bi-directional authentication, each side independently sends
an Authenticate-Request (AUTH−REQ) and receives either an
Authenticate -Acknowledge (AUTH−ACK) or Authenticate- Not
Acknowledged (AUTH−NAK).
This procedure describes how to do password authentication
protocol (PAP) on ZTE ZXR10 GER.
