Research And Implement Of Advanced Anonymous Communication System

Going with the development of net work technology, the needs of anonymous communication applications are increasing and the anonymous communication system has appeared. The purpose of this system is to protect one side or both from being attacked. That makes the communication safe. In the anonymous communication system, securities and anonymities are two blades of a sword. The approach of enhancing the performance and ensuring the securities at the same time is a crucial researchful area.This discourse analyzes popular anonymous communication system. It includes JAP system, Picidae system and I2P system. On the strength of these analyses, I take up an advanced anonymous communication system model bases on I2P anonymous communication system. Firstly, the paper improves on peers' distribution strategy. Secondly, the paper mends the approach of choosing way based on I2P peers' locations. I will choose peers who are very close to build the communication tunnel. At the same time, the paper changes the peer updating algorithm which makes the anonymous system have the higher level security. Finally, the paper takes up a new way for client distribution in order to prevent the peers of system from gather by the attacker. And then, it will protect the code of I2P and store or backup it as will. All of these improve on the security and anonymity of I2P system.
