Design of solution for network security authentication with EPASS1000

Authentication is a very key part for network security. So the solution for network security authentication based on EPASS1000 was put forward. EPASS1000 is a portable device that is connected to computer via USB port and has a built-in MD5 encrypted algorithm, which introduces free-factor in plain text and result in the different cipher texts in different encryption processes. The solution integrates the security of EPASS1000 with the actual application of network perfectly. It depicts the implementation of security authentication process, constructs the logic model for network authentication and also gives an example program written in ASP(Active Server Pages), which solve effectively the problem about the network security authentication.
