Design And Prototype Development Of Identity Authentication Mechanism In Information Security Of Intelligent Vehicle Network

In recent years,the intelligent networked automobile industry has developed rapidly,and the society and the country have paid much attention to the intelligent networked automobile industry.Intelligent,networked,low-carbon and environment-friendly intelligent networked automobiles have become the future development trend of the automobile industry.The global technology giants have also launched their own implementation plans of driverless technology.Intelligent vehicle network refers to the intelligent network with the car as the terminal node,through the advanced Internet technology to connect people,cars,roads and other facilities together,to provide a safe and efficient intelligent network for travel.At present,in the field of intelligent Internet of vehicles,the functional achievement of realizing intelligent Internet of vehicles has been relatively perfect,but in the new application scenario of intelligent Internet of vehicles,the research and application of intelligent Internet of vehicles on attacks and information security are relatively backward.This paper studies the identity mechanism of intelligent Internet of vehicles,and develops a prototype of the application scenario of digital key,verifies the identity authentication mechanism under the digital key scenario,and guarantees the information security of users and vehicles.This paper introduces the information security background of intelligent vehicle network and analyzes the importance of identity authentication in intelligent vehicle network.Based on the analysis of the key objects in the Internet of vehicles,the identity authentication scheme under the "end-net-cloud" structure of the intelligent Internet of vehicles is obtained.By using digital certificates,challenge response,multi-factor authentication and other solutions,the scheme solves the identity authentication problem existing in intelligent vehicle network,and ensures the information security and reliable transmission between intelligent networked vehicles,cloud service platforms,mobile devices and users.The thesis deploys the identity authentication scheme for the application scenario of digital key in intelligent Internet of vehicles,and develops and tests the prototype.Firstly,the requirements of digital key prototype are analyzed.In the functional requirements,the core function points,namely certificate management,registration and login,user center and vehicle status and control,are introduced.On this basis,the authentication scheme and the interface before and after the prototype are designed,and then each module in the prototype is designed and developed.The prototype is tested through the application of digital key in intelligent Internet of vehicles,the security of the authentication mechanism and the application of digital key in intelligent Internet of vehicles is verified,and a reference scheme is provided for the authentication mechanism of intelligent Internet of vehicles to ensure the information security of intelligent Internet of vehicles.
