A Solution to Prevent Resource Conflict and Paging Channel Hijacking in the Internet of Vehicles

With the development of the Internet of Vehicles, the security of the Internet of Vehicles has received more and more attention. However, in the Internet of Vehicles, the traffic topology changes rapidly and the vehicles are always in high-speed motion, so the secure communication between vehicles is more vulnerable to be damaged. Aiming at resource conflicts and channel hijackings that are prone to occur in the Internet of Vehicles, this paper proposes a scheme based on blockchain and time stamps to prevent resource conflicts, and selects the base station with the highest reliability by scoring the base stations, avoids paging channel hijacking, prevents vehicle terminals from accessing malicious base stations, and improves the security of the Internet of Vehicles.
