Modeling and Analysis of Email Worm Propagation Based on Stochastic Game Nets

Abstract

In this paper, we propose a model of email worm propagation based on a novel modeling method, Stochastic Game Nets (SGN), and use this model to analyze the rampant propagation issues of email worm. Combination the conceptual framework of SGN with the practical problems, we get some remarks based on the definitions of SGN in order to precisely describe the details of email worm propagation. An algorithm for solving the equilibrium strategy is presented to calculate the model of SGN. Finally we analyze our research result with several figures, such as infection rate and average propagation time. The results of our work can also offer some references for email users to defend email worms.
