Construct the Secure Shell Transport Model and Analyze Its Security Performance

The network management protocol SNMP has its flaws,but it has not solved by itself. So other secure protocol must be borrowed to deal with the flaws of SNMP. It is a good method that the Secure Shell Protocol(SSH) can resolved the flaws of SNMP. In this paper the Secure Shell Security Model is constructed based on the SSH and analyzed its performance, which is good to the network security management.
