SSH is a protocol for secure remote login and other secure network services over an insecure network. Replacement for telnet, rsh, rlogin, etc. Developed by SSH Communications, Finland. Specified in a set of Internet drafts. Two distributions are available: Commercial version. Freeware (www.openssh.com) SSH Layers. SSH Application.
Secure Shell (SSH) Protocol is a protocol for secure network communications designed to be relatively simple and inexpensive to implement. The initial version, SSH1, focused on providing a secure remote logon facility to replace Telnet and other remote logon schemes that provided no security [4].
29 Νοε 2023 · In this tutorial, we will cover the SSH basics, along with the underlying mechanisms used by the protocol to offer a secured method of remote access. We will cover the different layers and types of encryption used, along with the purpose of each layer.
The SSH Protocol Connects to a remote host and uses Diffie Hellman or RSA public key cryptography to exchange a secret key. Uses secret key for transport encryption with a symmetric cypher, usually using Blowfish, AES or 3DES. Also supports PKI authentication and authorization.

Secure Shell is a protocol that provides authentication, encryption and data integrity to secure network communications. Implementations of Secure Shell offer the following capabilities: a secure command-shell, secure file transfer, and remote access to a variety of TCP/IP applications via a secure tunnel.
