An identity-based message authentication scheme for Internet of vehicles

The Internet of Vehicles realizes information sharing through the interconnection between entities such as vehicles and vehicles, vehicles and roads. As the computing tasks of vehicles become more and more complex, the data load of traditional cloud computing centers also increases. If a large amount of data generated by the vehicle is all uploaded to the cloud server, and the data is processed by the cloud computing center, it will increase the burden on the cloud server. In order to reduce the request time in the vehicle and reduce the data transmission delay, edge computing is introduced, and an identity-based vehicle networking message authentication scheme in the edge computing scenario is designed to realize the rational use of computing and storage resources. The scheme satisfies unlinkability, unforgeability, identity privacy protection, and anti-replay attack.
