Abstract

Abstract: As the main body of information interaction perception of Internet of Vehicles, intelligent connected vehicles aim to achieve intelligent management, efficient control and timely scheduling of intelligent transportation through the establishment of message interconnection and transmission system among on board units, cloud, road side units and humans. However, illegal network intrusion and cyber-attacks lead to security risks in the multi-communication scenarios of Internet of Vehicles. In order to solve the problem of identity identification at all communication terminals and the message security transmission mechanism in complex communication scenarios, identity authentication technology becomes an important guarantee for the security system of Internet of Vehicles. The basic ideas of research works are as follows. By summarizing the research status and results of Internet of Vehicles at home and abroad, the platform, components and communication system of intelligent connected vehicles are proposed, the security architecture based on digital certificate is constructed. By researching the intrinsic characters of security framework in depth, each terminal architecture is designed in detail based on the security requirements, full life-cycle security mechanisms are integrated into the architecture, the personalized identity authentication service within the whole life cycle of multiple scenes is realized. This paper analyzes the actual needs of the V2X certificate management and the LTE-V2X technical characteristics. And then a digital signature system based on LTE-V2X is proposed, which can actually be applied to the development and design of LTE-V2X service deployment and related systems.
