网络蠕虫扩散的研究

Research of Network Worm Diffusion

近年来,随着网络系统应用及复杂性的增加,网络蠕虫成为网络系统安全的重要威胁,因此研究网络蠕虫的扩散十分重要。本文介绍网络蠕虫以及扩散的基本定义,分析网络蠕虫的扩散机制,并在此基础上讨论基于P2P技术的网络蠕虫的特性,给出P2P网络蠕虫扩散的扫描策略以及相应算法。最后给出网络蠕虫研究的若干热点问题与展望。

Recently the explosive growth of network applications and its complexity,and the threat of Internet worms against network become serious increasingly. So the technology research about the Internet worm is very important. The author introduces the definition of worm and diffusion,and analyses the mechanism of diffusion of network worm.Then based on which,discusses the character of network worm using P2P technology,and put forward the scanning strategy and algorithm of diffusion of P2P network worm.Finally the critical techniques of Internet worm prevention are given,Some major problems and research trends in this area are also addressed.
