Research And Implementation Of Intelligent Remote Upgrade Technology For Intelligent Network Connection Vehicles

Today,people's lives are increasingly dependent on vehicles and the Internet.The integration of people,vehicles,and cloud computing is inevitable.It is urgent to make the vehicles to be connected and informatization.As the next generation of smart travel terminals,intelligent and connected vehicles are faced with increasingly complex demands,and the development of intelligent and connected vehicles terminal security remote upgrade technology is imminent.However,most of the vehicle terminals do not have the remote upgrade technology yet.The data must be written on the site through the reserved communication port to update the app or firmware.This method has the problems of inconvenient updating and maintenance of the vehicle terminal system,poor real-time performance,and insecurity.For this kind of situation,this thesis analyzes the security threats faced by intelligent networked vehicles.Based on the features of intelligent and connected vehicles' hardware,diverse performance,complex network conditions,and high reliability requirements,this paper research and implements a secure remote upgrade technology.The technical scheme is a security remote upgrade scheme with wide applicability,high security,convenient update method and complete update types.The technical scheme using identity authentication,key management,secure transmission technology,safe storage technology,digital signature technology,symmetric and asymmetric encryption technology,combined with hardware encryption machine,safe storage hardware intelligent SE card,Telematics hardware Box,etc.The technical scheme has the advantages of good real-time performance,high reliability,real-time performance and good audit performance.Under various simulation scenarios in the process of security remote upgrade,the designed security remote upgrade technology scheme can carry out the remote upgrade of intelligent and connected vehicles safely and without any error,and the test has verified the feasibility,reliability and security of the proposed security remote upgrade scheme.
