Analysis Of Ship Network Security Regulation Decision Based On The Evolutionary Game Theory

In the context of the era of big data,intelligence has become an inevitable trend of the development of the ship.It is more safe,more environmentally friendly,more economical,more reliable to make the ship run more intelligently.With the continuous development of intelligent ship,network security has become a topic of growing concern.The ship is facing the threat of network security from many aspects,such as program operation errors,software defects,intrusion system,unauthorized access to the management company with effective risk control program on the network to.In recent years,with the continuous improvement of the level of intelligent ship,the ship is more and more in the "online" state,but also the risk of network security threats gradually increased.The industry has made a lot of research,and in reducing the risk of ship network security,to provide solutions to the relevant aspects of the effort.To ensure the safety of the ship network,not only the behavior of the shipping company,but also the maritime sector to play the role of government regulation,in order to achieve better results.Therefore,this paper will study the behavior of the maritime sector and the behavior of the shipping company by means of evolutionary game theory.Through the supervision of behavior and behavior of the shipping company in the maritime sector to understand and sort out the basis of the relevant literature,put forward the hypothesis and the related variables,and then constructs the evolutionary game model of the maritime sector and the shipping company interactive strategy.The dynamic equations of the maritime sector to adopt the regulatory strategy and the ship companies to upgrade the network security equipment strategy are derived.The replicator dynamic equation and the Jacobian matrix to analyze players in six different combinations of parameters under the condition of dynamic evolution path.The results show that in the long term after repeated games,there will be three kinds of stable strategies(i.e.,regulation,upgrade),(no regulation,no upgrade)and(supervision,not upgrade).The pressure research results,the maritime sector supervision,income supervision cost,supervision efficiency,to the shipping company not to upgrade the punishment and the shipping company to upgrade the network security equipment costs,these 5 parameters can affect the size of the convergence results of the system,making(regulation,upgrade),(no supervision,no upgrade)and(supervision,upgrade)could be the evolutionary stable strategy system.Therefore,in order to ensure the safety of the ship network,it is necessary to reasonably design the relationship between the 5 parameters,to guide the behavior of the ship company to upgrade the goal of evolution.
