对等网络蠕虫建模与分析

Modeling and Analysis of P2P Worms

对等网络蠕虫是威胁对等网络乃至Internet安全的一个重要问题。针对蠕虫扩散过程和对等网络拓扑的特点,构造了对等网络蠕虫传播模型;以Gnutella网络为研究实例,获取其拓扑快照数据,用以模拟蠕虫在Gnutella网络中的传播过程,从而验证模型的有效性,衡量对等网络蠕虫对P2P网络的危害。

P2P worms are the most serious threats to P2P applications and lnternet security. This paper presents a novel P2P worm spreading model, which considers the P2P network topology characteristics. The numerical simulation results based on Gnutella topology snapshots indicate that the spreading model can provide a set of metrics to evaluate the harms of P2P worms.
