互联网蠕虫因其对互联网的巨大威胁而引起了极大的关注。由于网络蠕虫的快速传播特性，有必要在互联网上实施自动缓解。受蠕虫疫苗接种的启发，我们提出了一种将疫苗接种和动态隔离方法相结合的新型传染病模型SEIQV模型。利用SEIQV模型，我们得到了决定蠕虫是否灭绝的基本繁殖数。研究了不同参数对该模型的影响。仿真结果表明，该模型在减少被感染主机数量和降低蠕虫传播速度方面明显优于其他模型。(C)2009爱思唯尔有限公司。保留所有权利。
Internet worms have drawn significant attention owing to their enormous threats to the Internet. Due to the rapid spreading nature of Internet worms, it is necessary to implement automatic mitigation on the Internet. Inspired by worm vaccinations, we propose a novel epidemic model which combines both vaccinations and dynamic quarantine methods, referred to as SEIQV model. Using SEIQV model, we obtain the basic reproduction number that governs whether or not a worm is extinct. The impact of different parameters on this model is studied. Simulation results show that the performance of our model is significantly better than other models, in terms of decreasing the number of infected hosts and reducing the worm propagation speed.
