Research on P2P-based Anonymous Communication Technology
基于P2P的匿名通信技术研究

With the development and wide use of P2P networks, user privacy and security come to be valued continuous- 1y. Although the content of correspondence data can be protected by existing encryption which can not protect the user's identity very well, we can't give outlaw the opportunity to spread the illegal information when the anonymous technolo- gy is used. hherefore, this paper put forward a method based on acyclic packet routing mechanism to achieve the anony- mows communication in P2P system, communicate privacy and confidential communications by cutting network address, protecting members group, and uniformly managing group administrator. Simulation results show that routing strategy has been improved obviously by the mechanism. The mechanism can guarantee communication efficiency while impro- ving the anonymity of user,and the P2P network can be protected in real-time effectively.
