P2P蠕虫遏制方法的研究与建模

Research and Modeling of P2P Worm Containment Method

传统的蠕虫遏制方法无法及时地遏制P2P蠕虫。针对该问题,提出一种基于P2P良性蠕虫的快速遏制方法。P2P良性蠕虫利用P2P软件漏洞进行自动传播,能够清除恶性蠕虫并修补软件漏洞,从而彻底阻断恶性蠕虫的传播渠道。对该遏制方法进行数学建模,给出相应的离散差分数学模型。仿真实验验证,该方法遏制效果好且对网络资源消耗少。

Traditional methods are not competent to quarantine Peer to Peer（P2P） worm in time.Aiming at this problem,this paper brings forward a fast containment method based on benign P2P worm.Benign P2P worm automatically propagates itself through software vulnerabilities.It is able to eliminate malicious worm and fix software vulnerabilities,thus it prevents the propagation of malicious worm outright.The method is efficient and has few bandwidth resources consumption.It models the method and proposes the related discrete difference model.Simulations validate the efficacy of this method.
