Research On Network Virus Attack And Defense Strategy Based On Incomplete Information Game Theory

The development and application of the Internet since its inception to the present day has brought great convenience to people's life,study,and work environment.The Internet has penetrated into all aspects of society.However,Internet viruses have also experienced rapid development in relying on the Internet.People are enjoying the convenience brought by the Internet and are also affected by the virus on the Internet.Therefore,network security has become a hot topic nowadays.How to effectively prevent computer virus intrusion has become a very important issue.Based on the characteristics of common computer viruses,how to accurately establish the propagation model of computer viruses in the network,and accurately determine or predict the next trend of the virus according to the characteristics of the virus,so that we can take some defensive measures in advance to block malicious viruses to the host the further invasion of the computer to reduce the loss of the host user has become the research goal of the network security defense system.This article starts with the analysis of the relevant characteristics of the virus,analyzes several representative classical models of computer viruses,and uses the related concepts of game theory to simulate network viruses and host computers as participants in game theory and analyze the spread of network viruses.The strategic choices in the process of intrusion propose reasonable recommendations based on repeated game theory to effectively resist the virus intrusion.Based on the current research on computer viruses in related fields at home and abroad,the game relationship between defense systems and invading viruses is highlighted,and the feasibility of using game theory to analyze the process of virus intrusion into the host is proposed.And hereby put forward the research plan of this article.Using the type and main characteristics of computer viruses in the Internet,a detection model of network virus intrusion phase was constructed,and the influence of strategic choices of game participants in the model on revenue was analyzed.Based on this,an effective improvement of virus defense was proposed.Measures approach.Finally,the simulated virus propagation model is mathematically expressed,the game process is further elaborated,and the quantified game simulation experiments are conducted to analyze and summarize the participants' returns and expectations to achieve the optimal state of the policy decision.
