Application And Verification Analysis Of Commercial Cryptography Of Intelligent Networked Vehicle

Intelligent transportation is a currently popular research field.Among them,intelligent connected vehicles as a core element have attracted wide attention from all sectors of society.By integrating vehicle networking and intelligent vehicles,equipped with advanced on-board sensors,controllers,actuators,and other devices,and combining modern communication and network technology,intelligent information interaction and sharing between vehicles,people,roads,and back-end systems has been achieved,thereby promoting the development of vehicle intelligence.However,in the process of achieving the networkization and intelligence of traditional vehicles,intelligent connected vehicles also face some problems.Especially,there are security issues with low support for domestic cryptographic algorithms.There are security problems such as messages being tampered with or forged in the authentication of vehicles and roadside units,which pose a great threat to the safe development of intelligent connected vehicles.Therefore,we need to strengthen relevant research work to solve these problems.This paper will propose an application technology based on domestic cryptographic algorithms and the intelligent connected vehicle field,combined with the formal implementation background of China’s "Cryptographic Law," to ensure the security and integrity of information transmission.This paper primarily focuses on the following research areas:(1)Analyze the problems existing in the existing password application in typical automobile scenarios,comprehensively and comprehensively analyze the password application risks faced by vehicle-vehicle/vehicle-road communication and vehicle-cloud communication,and design security against these risks.(2)In view of the defects in the current password application scheme in the automobile industry and the difficulties in the landing application of domestic commercial passwords,a vehicle-vehicle/vehicle-road communication scheme based on the SM2/SM3/SM4 algorithm and short certificate,and a vehicle-cloud data transmission and identity authentication password application mechanism based on the SM2/SM3/SM4 algorithm and TLCP cryptographic protocol are designed to meet the current situation of the automobile industry password application.(3)Deeply study the core elements of the password application scheme,carry out the verification and analysis of the password application test,verify the rationality,completeness and feasibility of the scheme design by testing,and provide reliable data support for the industry promotion.
