Asymmetric information countermeasure in networks and corresponding Nash strategy

According to the Nash equilibrium solution problem for asymmetrical information countermea-sure in networks, an idea of cumulative cost is developed to analyze the cost functions in the case that the system subjects to stochastic disturbances. In this model of information countermeasure, players include two parties, namely, the control group and the disturbance group. The goal of the former is to minimize its cost function and its variance, but the goal of the latter is only to minimize its cost function. Moreover, the Nash equilibrium solution to each player is also given when the network system is linear based on the sufficient condition. Finally, an illustrative example is presented to show the characteristics of the asymmetrical information countermeasure in networks.
