在对计算机蠕虫的研究中，常常借用传染病传播模型，通过研究双要素蠕虫传播模型，提出了一个改进的蠕虫传播模型，并通过Matlab仿真进行了相关试验，证明该模型可以更好地预测蠕虫传播的规模和速度。关键词：传播模型；蠕虫；双要素Abstract: The model of the spread of infectious disease have always been adaptedto the study of the computer worm. Based on the study of two-factor worm propagationmodel, present an improved worm propagation model. And then through some relatedexperiments simulated by Matlab, proved our new model could more better forecast thescale and speed of worm spreading.Key words: propagation model; worm; two-factor
