摘　　要：多数蠕虫传播模型都是基于简单的随机扫描,蠕虫形态相对固定。为此,研究排列扫描技术,结合自然生物的取食繁殖规则,提出一种多态蠕虫动态传播的数学模型。通过一系列相互独立的方程表现蠕虫的整体行为,计算传播过程中各类被感染蠕虫的数目。仿真实验结果表明,该模型能准确描述多态蠕虫的传播过程。Most of models are based on single random scanning, and worm has relatively fixed morphology. In view of this problem, this paper researches on permutation scanning technique, combines natural biological feeding and breeding rules, and proposes a mathematical model to characterize the dynamic propagation of polymorphic worms. The overall behavior of the worm is presented and the number of different type of worms in the process of propagation is analyzed by a series of inter-dependent equations. Experimental simulation result shows that this model can describe polymorphic worm propagation exactly.
