Based On The Rerouting Anonymous Communication System Design And Implementation

With the development of Internet technology, Network communication became an important part in people’s daily life.And network information security become more and more attention. The content of the network traffic, encryption and decryption technology can effectively ensure the security of the mmunication content.In Internet design stage, People did not consider the security of the communication behavior.Nowadays, The communication protocol is TCP/IP protocol. But the communication protocol is expressly, and attackers can analyze the communication packets to find communication relationship. Therefore, Communication behavior can not be effectively hidden by encryption and decryption in the Internet.In order to solve the security of the network traffic behavior, This topic was designed and implemented a anonymous communication systems which can hide the communication behavior by Re-routing technology. To solve the communication behavior that can not be hidden defects on the Internet.The subject on the basis of Re-routing anonymous communication technology, information hiding technology, combined with TCP/IP protocol communication features, designed and implemented one based on the re-routing of real-time anonymous communication systems. And make some effectiveness testing on the system.The main contribution of this project are as follows:(1) Analysis of reroute anonymous communication technology. Proof of anonymous communication system based on the re-routing technology is feasible. This system can provide users with a stable, legitimate and effective anonymous communication protection;(2) To achieve Anonymous communication server. The Server can provide a anonymous communication path, and which can ensure the safety of users;(3) To achieve anonymous communication client. The user to safely use the anonymous communication systems;(4) To achieve anonymous communication forwarding node, Making a valid mailing address in the communication message constantly change, and ultimately ensure the safety of the user communications between;(5)In summary, Entire rerouting-based anonymous communication systems. And make some effectiveness testing on this system.Test results show that, We designed the system to meet the requirements of covert communication, anonymous communication services to ensure the stability of legitimate users.
