NAME
secsh - the Secure Shell protocol
DESCRIPTION
secsh
is a protocol suite for secure remote login and other secure network
services over an insecure network. It is outlined in
[SECSH].
It has three major components:
The Transport layer protocol
This protocol, specified in
[SECSH-TLP],
provides server authentication, confidentiality, and integrity with perfect
forward secrecy.
The User authentication protocol
This protocol, specified in
[SECSH-AUTH],
is used to authenticate a client to a server.
The Connection protocol
This protocol, specified in
[SECSH-CONN],
multiplexes an encrypted tunnel into several logical channels.
IMPLEMENTATIONS
Several implementations of the secsh protocol suite exist.
The
SSH2
product of SSH Communications Security Ltd., Finland <URL:http://www.ssh.fi>
was the first. The secsh protocol suite has benefited a lot from their
experience with their older SSH1 product, which is still in widespread use;
it implements an older protocol
([SSH1]).
The
lsh
suite of programs is a free implementation of the secsh protocol suite; it
is distributed under the GNU General Public License.
