| Summary: | A stochastic model of Internet worms is presented.Firstly,the propagation of worms is modeled based on Markov chain.The limit distribution and invariant distribution of the model is discussed.Then,necessary and sufficient conditions of the worm propagation in the initial stage and sufficient conditions of the worm propagation in the late stage are discussed.Finally,the scale of the worm propagation is discussed.The simulation validates the model.And the effect of propagation,time and vulnerable host parameter on the spread of worms is discussed.Furthermore,it is compared to the G-W model,and the advantage of it is illustrated. |
