SSH(Secure Shell) Protocol

One of the biggest challenges in using the Internet to replace more traditional communications is Security. In the past, companies have maintained their own modem bank dial-up access to company resources so that critical data wasn't being transmitted over the public network. Secure Shell is a protocol that provides authentication, encryption and data integrity to secure network communications. Secure Shell offers a good solution for the problem of securing data sent over a public network. For example, using Secure Shell and the Internet for securely transferring documents and work products electronically, rather than using a traditional overnight courier can provide a substantial cost savings. We propose a mobile SSH protocol which employs an application-layer handover mechanism. We have implemented the proposed SSH protocol like Open SSH and Putty. With the proposed protocol, the mobile users can switch from one wireless network to another without terminating their SSH sessions.
