一种基于P2P网络的蠕虫传播模型研究

Research on a Worms Propagation Model Based on P2P Networks

P2P蠕虫是利用P2P机制进行传播的恶意代码。本文针对基于P2P(peer-to-peer)的大规模网络,对P2P蠕虫的传播展开相关研究。首先介绍三个基本的蠕虫传播模型,分析了引入良性蠕虫后的四种情况。然后根据几个P2P蠕虫的扫描策略之一,提出了基于P2P系统的网络对抗蠕虫传播模型,并进行了初步的模拟分析。

The P2P-based worm is a kind of malicious code that takes advantage of P2P system to propagate. The P2P worms propagation is researched based on P2P （peer-to-peer） large-scale networks. First, this paper introduces three basic worms propagation models and analyzes four situations after the introduction of benign worm. And then according to one of several P2P scanning strategy , it puts forward a benign worms propagation model based on P2P system, and carries out a preliminary simulation analysis.
