Application Research Of Game Theory In DDoS Attack

Game theory is a theory that studies how decision makers decide actions and strategies.DDo S attacks are distributed denial of service attacks(Distributed Denial of Service).If the attacker and the defender in the network are regarded as players in the game,then game theory can be used to discuss and study the relationship between the attacker and the defender.To this end,while studying DDo S attacks,this paper introduces game theory to combine DDo S attacks with game theory.The main work of this article is as follows:First,the thesis expounds the importance of DDo S attack research in computer networks,and explains the scope and content of game theory and its application research in network security and DDo S attacks,and proposes the usefulness of game theory to strengthen the effect of DDo S attacks.Secondly,on the basis of the previous part,the basic ideas of game theory are introduced and classified in detail.Some commonly used DDo S attacks,defenses and detection methods are introduced in detail,and the network attack and defense model and game theory model are combined A comparison is made,and it is found that the offensive and defensive model and the game model are equivalent to some extent,and the four elements of game theory can also be seen in the offensive and defensive model.Thirdly,the thesis combines game theory and proposes a game theory DDo S attack model.First,it provides a schematic diagram of the attack and defense game for the establishment of the model,analyzes the network scenario,and then briefly introduces the traditional DDo S attack.Unlike the four elements of game theory,it only analyzes its participants and the actions that the participants will take;The game theory attack model is analyzed,and the benefit function of both sides of the DDo S attack game model is analyzed,which lays the foundation for the experimental demonstration in the latter chapter.Finally,the thesis analyzes the offensive and defensive environment and the experimental results.The experimental results prove that compared with the traditional DDo S attack model,the game theory DDo S attack model is introduced,which can have a greater impact on the server.
