Design And Simulation Of Autoimmune P2P Node

P2P security problems attract more attention as the fast development and wide Application of P2P technology. The new characters of distribution and self-organization which P2P network has prompt the development of security problems and traditional security technologies can not totally resist them. However,as compound of client, server and router, P2P node has advantages to detect attacks and network anomalies.This paper aimed to design and realize P2P node with autoimmunity function. This kind of structure can make the participates of network can defend security threat and evade network anomalies to reach autoimmunity effect.First, this paper present comprehensive and systematic analysis of P2P security problems.relationships between attacks are analyzed. Understanding their relationships will help to build security mechanism. Then identity theft detection arithmetic are studied. As an important part, this paper design the structure of autoimmune P2P node and the module division. In this framework, three detection arithmetic are implemented and related experiment data are exported and analyzed. To cooperate this experiment, we build attack system as while. Both of them will be contributed to open source community and further study tools.
