P2P安全的风险分析与保障策略

Security Risk Analysis and Protection Policy for Peer to Peer Networks

P2P网络和应用发展迅猛,从文件共享、服务共享、即时通信到视频传播等,其涉及的领域不断扩大,对网络发展、人们生活和社会经济发展都产生了深刻的影响。同时,P2P引起了很多安全风险并给网络安全带来了新的挑战,如果不能解决这些安全问题,必将对网络安全、个人/企业/社会利益带来侵害,影响到信息化的发展和健康网络环境的建设。然而,现在对于P2P安全,缺乏全面、深刻的分析,在安全技术研究方面也仅仅是处在被动防御的地位。该文从整个网络安全、网络环境的角度,分析了产生P2P安全问题的原因、涉及到的安全问题;对现有网络安全技术的局限性与P2P安全要求进行比较;进而全面分析了P2P安全风险;最后提出了构建P2P信任体系,加强对新安全理论与技术的研究,实现"监控、监管、安全保障"的P2P安全目标,支持P2P网络和应用健康发展。

Peer to peer networks and applications expand faster, and the developing trend of p2p would influence peoples＇ life. At the same time, there will come forth many new security risks, which influence network security. In order to protect the benefits of society, companies, and peoples, this paper gives a particular analysis form the viewpoint of network security and environments. Building trusted architecture of networks, enhancing research on security theory and technology, are bright forward.
