Mixed Strategy Analysis in Attack-Defense Game Model Based on 5G Heterogeneous Network of CPS Using ncPSO

The development of the 5th Generation Mobile Communication Technology not only brings convenience to people but also many network security problems. Based on static game theory complete information, a model attack and defense with limited resources in heterogeneous networks Cyber Physical Systems is established. This analyzes basic rules offensive defensive strategies both parties when are environment. can describe interaction between attackers defenders. A novel compact particle swarm optimization algorithm proposed solve difficult problem solving Nash equilibrium this model. simulation experiment proves that has good ability shows effectively provides strategic reference for attack-defense resources.
