拓扑相关蠕虫仿真分析

从蠕虫传播的漏洞主机发现、代码传播以及代码启动3个方面提出了一个完整的数据包级拓扑相关蠕虫仿真模型,设计了基于有向图的SmallWorld拓扑结构生成算法,并通过选择性抽象在NS2上实现了一个完整的数据包级拓扑相关蠕虫仿真系统.最后,通过该仿真系统实验分析了逻辑拓扑结构和蠕虫代码启动方式对蠕虫传播的影响.仿真实验结果表明,该仿真系统可以为拓扑相关蠕虫研究提供重要的支持.

Topology Aware Worm Simulation and Analysis

This paper provides a complete packet-level topology aware worm simulation model based on worm targets discovery,worm code transmission and worm activation,and designs a directed Small World topology generation algorithm.Then,through selective abstraction,this paper implements a complement packet-level topology aware worm simulation system.Finally,with simulation experiments,the paper analyzes the impacts of topology structure and worm activation on worm propagation.The results of simulation experiments show that this simulation system can provide great support for topology aware worm research.
