Research on Blockchain-Based Identity Verification Between IoV Entities

As the outcome of the reform of the automobile industry driven by mobile communication, automotive electronics and new automotive bus, Internet of Vehicle(IoV)will make differences in the transport system. Located in the terminal layer, Connected Vehicles(CVs) will bind to people's daily lives. One current mainstream CV access approach to a network is cellular-based V2X(C- V2X), CV are vulnerable to be deceived during the access process form illegal entities such as fake base stations and terminals. To protect access, we designed an identity verification method based on blockchain. Considering that vehicular terminals have limited computing performance, we reduced the complexity and procedures as much as possible to meet the low latency requirement. The result of security analysis shows that this method can fulfill efficiency and security requirements in communication scenarios between CV and other entities.
