A Non-cooperative Game Approach for Intrusion Detection in Smartphone Systems

In this paper, we propose an intrusion detection framework for smartphone systems. We formulate the intrusion detection problem into a two-player, non-cooperative, complete-information, constant-sum game. The attacker and the security server are the players of the game. The security server wants to maximize the value of the system but the attacker wants to minimize it. We present the Nash equilibrium and the Nash equilibrium leads to a defense strategy for the security server. We implement the framework and the results show that the proposed defense strategy is better than traditional ones.
