At first the text introduce the significance of SSH, then state the encryption techniques, implementation model and introduce the meaning of network security. And in the end set up the environment of encryption transmit-ssion for SSH. The virus invasion becomes more and more serious, makes us begin to research various technology for preventing the invasion of virus. SSH encryption technique is a very important part of them. We work out different security protocol according to the demand for security of different levels for network so that providing better service for encryption and authentication. Each protocol is located in the different levels of computer ar
