The invention discloses an Internet of Things equipment encryption method based on IBE in an Internet of Vehicles environment, which is mainly used for solving the efficiency problem of intelligent automobile data calculation in the Internet of Vehicles environment. The encryption process is divided into an external device encryption stage and an online encryption stage. In the encryption stage ofthe external device, before the identity and plaintext of a receiver are obtained, all operations (such as exponential operation and pairing operation) with high calculation complexity are calculatedin advance, and an offline ciphertext is formed. In the online encryption stage, when the identity and the plaintext of the receiver are received, other encryption operations are calculated on the node. Meanwhile, the bilinear pairing calculation algorithm in the encryption and decryption process is optimized, the time complexity of the encryption process is reduced, and the data encryption transmission processing efficiency of the Internet of Vehicles is improved.
Description
technical field [0001] The invention relates to an IBE-based encryption method for an Internet of Things device in an Internet of Vehicles environment, and belongs to the technical field of the Internet of Things. Background technique [0002] As a specific application and important branch of the Internet of Things in the field of ground transportation, the Internet of Vehicles organically integrates technologies such as mobile computing, automatic control, and wireless communication, and collects road environment and communication information between nodes in real time. The information sharing and interconnection of the road-processing platform provides services for various traffic management systems, achieves the purpose of saving resources and improving traffic efficiency, and provides convenience for the public to travel. With the increasing number of cars, road traffic safety incidents occur frequently, and traffic congestion, energy consumption, and air pollution are b...
