 PAP –Short for Password Authentication Protocol, the most basic form of
authentication, in which a user's name and password are transmitted over a network
and compared to a table of name-password pairs. Typically, the passwords stored in the
table are encrypted. The Basic Authentication feature built into the HTTP protocol uses
PAP. The main weakness of PAP is that both the username and password are
transmitted "in the clear" -- that is, in an unencrypted form.
 CHAP –Short for Challenge Handshake Authentication Protocol, a type of
authentication in which the authentication agent (typically a network server) sends the
client program a random value that is used only once and an ID value. Both the sender
and peer share a predefined secret.
