A survey of Internet of vehicles/vehicle to everything security based on Blockchain

Abstract

With the acceleration of the intelligent and networking processes of the automobile and transportation industries promoted by the IoV/V2X technology, the security problem of IoV/V2X is becoming increasingly serious. As an integrated application of distributed data storage, peer-to-peer transmission, consensus mechanism, encryption algorithms, and other technologies, Blockchain provides a new IoV/V2X security solution. This paper summarizes the research on Blockchain-based IoV/V2X security. First, it outlines the existing IoV/V2X security threats and protection methods, specifies the research value of Blockchain and IoV/V2X integration, and analyzes the Blockchain-based IoV/V2X security technology. Then, it sorts the existing Blockchain-based IoV/V2X security protection methods and their security architecture from the perspectives of communication security, data security, and application security. Finally, it proposes the development direction and research effort of Blockchain-based IoV/V2X security.
