摘　　要：Ad hoc网络的对等体系结构和节点资源受限使得其比传统网络面临更多的安全威胁。近年来,恶意程序研究已成为国际上网络安全和信息安全领域最前沿和最活跃的研究方向之一,无线网络中恶意程序研究已经开始成为恶意程序研究领域的一个新热点。首先分析了Ad hoc网络的网络体系结构及安全威胁、常见的恶意程序的分类及仿生物传播模型,然后从SEIR病毒传播模型的微分方程入手,针对该模型应用Ad hoc无线自组网出现的问题,引入网络拓扑特性和免疫延迟等概念对恶意程序传播模型进行了改进,结合网络拓扑动态演变恶意程序传播过程设计了一个改进的传播算法和动态免疫策略。综合考虑网络病毒传播特性、网络基础特性和免疫策略对改进模型进行了仿真实验分析,实验结果表明免疫策略和节点的度都影响恶意程序传播。Because of peer-to-peer system structure and node resources limitation, Ad hoc network faces more safety threat than the traditional network. In recent years, the malicious program research has become an international network and information security field forefront and one of the most active research directions in wireless network malicious pro- grams, also a new research field of hot. We first analyzed the Ad hoe network architecture and security threats, common malware classification and the biological modeling propagation model, then from the SIR virus propagation model of dif- ferential equations of the model, aiming at problems for the model to use wireless Ad hoc network, through the intro- duction of network topology characteristics and immune delay and other concepts of malware propagation model, im- proved network topology,and combining the dynamic evolution of malware propagation process, designed an improved algorithm and dynamic immune strategy. Considering of the network virus propagation characteristics, network charac- teristics and immunization strategy, a simulation experiment analysis of the improved model was made. The experimen- tal results show that both immunization strategy and node have effects on malware propagation.
