Authentication and encryption parameters
Authentication mode configuration
CHAP (Challenge-Handshake Authentication Protocol)
: It is one
encrypted authentication mode and can avoid transmitting the real password of
the user when setting up the connection. As for PPP, the key information does
not need to be transmitted in the communication channel during the
authentication. Moreover, the information exchanged during each authentication
is different. It can prevent the monitor attack efficiently and improve the security.
PAP
: It is one simple plain text authentication mode. It is required that the key
information is transmitted in plain text in the communication channel. Therefore,
it is easy to be listened by sniffer and leaked.
