摘　　要：针对P2P网络的反应式蠕虫,提出基于良性蠕虫的优先传播恶性感染节点的邻居节点(PRIN)遏制策略.蠕虫传播模型给出后,分析了PRIN策略的特点和可行性,并进行仿真实验.实验结果表明,与传统策略相比,PRIN策略进一步提高了蠕虫遏制效果,1‰数量的良性蠕虫即可有效遏制反应式蠕虫的传播,并在策略具体实施上忽略了良性蠕虫驻留节点类型的影响,降低了策略实施的复杂性.The strategy,prior reaction to infected peers＇ neighbors（PRIN） based on benign worm,was proposed to defend against reactive worm in P2P networks.After worm spread models were formulated,the characteristics and feasibility of PRIN strategy were analyzed and the simulations were given.The results show that the containment effect of PRIN strategy against worm is better than that of the traditional strategy.Only 1‰ peers infected by benign worm can effectively contain the spread of reactive worm.Moreover,the impact of the type of peers infected by benign worm is neglected and the complexity of implementation of PRIN strategy is reduced.
