A Certificateless Message Authentication Scheme for Internet of Vehicles in Edge Computing Environment

Through the interconnection between vehicles and vehicles, vehicles and roads and other entities, information sharing can be realized to improve traffic efficiency. A message authentication scheme based on certificateless aggregate signature was proposed to solve the problem of excessive computing and communication overhead in the Internet of Vehicles. In the new computing model of edge computing, the communication between the vehicle and the cloud is transformed into the communication between the vehicle and the edge node to reduce the communication delay. Certificateless cryptography eliminates the burden of certificate management and solves the key escrow problem. The aggregation signature technology reduces the signature length and storage space, and improves the efficiency of message verification. The scheme does not require bilinear pair operation, and reduces the computing cost on the premise of improving security. The scheme in this paper is more suitable for the Internet of vehicles environment.
