CHAP (Challenge-Handshake Authentication Protocol)
: It is one
encrypted authentication mode and can avoid transmit the actual
password of the user when setting up the connection. For PPP, the key
information does not need to be transmitted in the channel during the
authentication and the information switched during each authentication is
different, which can avoid monitoring attack 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 via the channel, so it is
easy to be monitored and leaked by sniffer.
MS –CHAP
: It is similar to CHAP. MS-CHAP is also one encryption
authentication mechanism, using MPPE-based data encryption.
MS2-CHAP
: MS-CHAP version 2.
EAP
: It is one expansible authentication protocol. The protocol is used by
the authentication in the point-to-point network, such as PPP. It can
support various authentication mechanisms. With the expansible
authentication protocol, any ID authentication mechanism can
authenticate the remote access connection.
Compression and control protocol parameters
Compression & Control protocol
Compression control protocol
: Responsible for the configuration on the
PPP link and negotiating which compression algorithm to adopt. And adopt
the reliable mode to identify the failure of the compression and de-
compression mechanism.
Address/control compression
: Whether to permit PPP packet address
domain and control compression setting.
Protocol domain compression
: Whether to enable the protocol domain
compression.
VJ TCP/IP header compression
: Whether to permit TCP/IP data to
perform the Van Jacobson header compression.
Connection ID compression
: Whether to permit the connection ID
compression.
