Extending SSH Authentication Protocol with RSA Secure ID
SSH (Secure Shell) is a protocol used to remotely login to another computer over a network. It provides a very secure communication channel using strong authentication methods and proven encryption algorithms.
SSH can be used as a replacement for the traditional remote access programs such as telnet, rlogin, rsh, rcp and ftp which are highly insecure because of their fragile authentication methods and the unencrypted data exchange. For eg., most of these programs send passwords in clear-text format during authentication and exchange unencrypted data to the server, thus becoming easily vulnerable to eavesdropping and network attacks.
SSH specification allows you to add stronger authentication methods to the existing set of methods to provide a highly secure and reliable communication channel.
