| 摘 要： | 提出一种基于动态检测隔离机制的通用网络蠕虫传播模型,该模型定义了蠕虫在隔离阶段的可疑状态,显式地刻画了蠕虫动态检测隔离过程;并利用动态蠕虫感染率和动态主机移除率、主机自动免疫率分别描述了蠕虫传播造成的网络拥塞现象和人类在对抗蠕虫病毒过程中的主观能动性.分析表明,基于动态检测隔离机制系统可有效降低蠕虫传播速度,减少被感染主机数,延迟蠕虫传播峰值出现的时间.

| Abstract: | This paper proposes a universal worm propagating model based on the mechanism of dynamic quarantine.The model defines the dubious state when worm stays in the phase of quarantine and depicts the process of dynamic quarantine explicitly.It also depicts packet loss caused by congestion of some routers and the mankind's initiative in the course of antagonizing the worm,by utilizing dynamic infecting rate and together with dynamic removing and auto-immunized rate. The analysis shows that the system based on the mechanism of dynamic quarantine can slow down a worm's propagation, reduce the number of infected hosts and delay the time when the worms burst out to the peak value. |
