Network Attack Defense Countermeasure Research

The paper considers a non-cooperative game which includes only designer and attacker. Begin with the network design, and assume that the designer also undertakes the obligation of defending the network while he is designing it. According to the different orders of the network design, defense and attack, mainly discuss the dynamic network design processes, which are carried out by the designer on the basis of the defense-attack results of each period.The ideas are brought up innovatively as follows:first, give the assumptions of payoff, successful-attack and spread of attacks of single-period network, the corresponding graphs and payoff-tables are shown. Second, facing to fixed numbers of nodes and resources, show the best design structure of network and the equilibrium theorem when the numbers become large. Third, establish the global optimal principles for the designer, that is, in a multiperiod dynamic network design environment, the principles of the designer to maximize the payoff summation when facing the strategic or random attack. Besides, also assume that the attacker aims at maximizing the period payoff. The primary contribution is giving the fundamental principles of the dynamic network design and defense.
