Research on information security cost based on game-theory

This paper analyzed the interdependence of information security issues, based on the expected benefit of cost and security loss of the interdependence of information security agents in a network, a model which simulates the information security cost analysis has been built. An information security cost game model is set up based on payoff matrix, the main strategy are divided into "investment security costs" and "do not input the security cost", which using Nash equilibrium and thus support the decision of the agents\´ security cost.
