摘要
提出一种新的网络蠕虫传播模型,并基于生物免疫原理提出了成熟良性蠕虫、记忆良性蠕虫和疫苗良性蠕虫新概念,建立了新的主机状态转移关系,运用系统动力学理论和方法,建立了一种新的网络蠕虫免疫模型,它能够从定性和定量两方面分析和预测网络蠕虫免疫过程,并能够深入刻画恶性蠕虫和良性蠕虫交互过程中的网络特性,为动态防治网络蠕虫提供了新的理论依据。模拟实验结果表明,引入的三种良性蠕虫是动态防御恶性网络蠕虫传播的重要因素。
A novel Internet worm propagation model is proposed.The mature friendly worms,memory friendly worms and bacterin friendly worms are defined based on the biological immune principles,and the uew transi- tion relations between host states are created.Based on the theories and methods of system dynamics,a novel Internet worm immune model is built based on biological immune principle,in which the process of Internet worm immune may be analyzed and forecasted qualitatively and quantitatively.In this model,the characteristics of alternating process of vicious worms and friendly worms can be depicted deeply.As a result,a novel theory for dynamic prevention of Internet worms is built.The simulation results show that the three friendly worms imported are important factors to dynamic prevention of Internet worm propagation.
