摘　　要：计算机网络对抗演练中一个重要的任务是在较短时间内仿真大规模蠕虫的爆发和蔓延。在研究蠕虫扩散机制的基础上,结合下推自动机理论,提出了一种描述蠕虫扩散仿真语言WSSL,WSSL由获权、传输和激活三部分组成,可实现蠕虫扩散活动的仿真模拟。针对所提出的仿真语言进行了自动机形式化推演,证明了其可行性。在GTNetS(佐治亚网络仿真器)和虚拟机构造的平台上,运用该语言实现了蠕虫仿真。结果表明,WSSL可以模拟指定漏洞的蠕虫快速扩散和传播,为研究较大规模的网络环境下蠕虫爆发与防御奠定基础。One of the important issues in computer network confrontation exercise is to simulate a large scale worm spreading events in a short time period.A novel spreading simulation language WSSL（worm spread simulation language）is proposed based on worm spread patterns and push-down automaton.WSSL consists of three components：access,transmission,and activation.The formal derivation is focused on and the feasibility of the WSSL is proved.The worms are simulated in GTNetS（Georgia tech network simulator）and virtual machine-based platforms by using WSSL.Simulation results show that WSSL can emulate the spread patterns of certain kind of worms very well,which paves the way for researches on the large scale worm explosions.
