一种新的P2P网络病毒防御模型

A New Model of P2P Networks Virus Defense

目前,P2P网络在文件共享、即时通信和协同工作等领域获得了广泛的应用,对网络的发展和人们的生活都产生了深远的影响.同时,P2P网络由于其自身自组织和非中心化的网络特点,给当前的网络安全带来了新的挑战.从病毒防御方面着手,首先介绍了目前主流的病毒防御技术并分析了这些技术的优缺点,然后对病毒防御技术的发展方向进行了探讨.最后在充分利用现有病毒防御技术的基础上,针对P2P网络环境的特性提出了一种新的方案.

Currently, P2P networks has has a wide range of applications, such as file sharing, instant messaging and collaborative work, etc. It has a profound impact on network development as well as people＇s lives. At the same time, because of the characteristics of self-organization and decentralization of the network, P2P networks brought new challenges to the security of the current network. Aspects from the virus defense, the paper first introduced the current mainstream virus defense technologies, analyzed the advantages and disadvantages of these technologies, and then discussed the development trend of virus defense technology. Finally, in the full use of existing virus defense technologies, the paper presented a new program based on the characteristics of P2P network environment.
