文件污染是P2P文件共享系统面临的主要安全威胁之一。由于没有中心机构监督用户行为及其共享的内容,恶意节点可以通过P2P传播病毒,木马等恶意内容,这些行为严重影响了P2P文件共享的系统性能。本文对P2P文件污染的研究现状进行综述,调查现有P2P系统中存在的文件污染现象及防御方法,分析了目前防御机制面临的问题。

File pollution is one of the primary security issues in P2P file sharing systems.As there is no central authority for content and identity authentication,malicious peers may easily inject invalid content into the networks to reduce system performance.In this paper,we focus on file pollution and defense mechanisms and analyze the technology challenges.
