The research and application of network trace-back technology

With the development of Internet technology and its applications, the boundary between virtual cyberspace and the real social environment is becoming indefinable. The cyberspace security has become a great threat and challenge which facing the governments and the whole society. Improve our technological capability of network trace-back is the basic way to solve the problem of Cyberspace Security.

Then, through more intensively study, the paper provides some technological solutions to dynamic IP trace-back, which be viewed as one of the most difficult problems in related field. The pilot program for IP Trace-back system which based on the technologies provided in this paper get a satisfactory result.
