Information Security Problem Research Based on Game Theory

Abstract

The purpose of this paper is to resolve information security problem in the mobile electronic commerce industry chain. We analyze information security based on evolutionary game theory. In this paper, we set up the information security game model with penalty parameter, calculate replicator dynamics, and analyze the evolutionary stable strategy of the game model. The result reveals that reducing the investment cost is the key factor to promote information security investment. If this condition can not be satisfied, the regulation of penalty parameter will help to promote the investment. The research method in this paper provides a new thought for the solution of information security in the mobile electronic commerce chain.
