Abstract

The invention discloses an IBE-based encryption method for Internet of Things equipment in an Internet of Vehicles environment, which is mainly used to solve the efficiency problem of smart car data calculation in the Internet of Vehicles environment. The encryption process is divided into two stages: external device encryption and online encryption. In the encryption phase of the external device, before the identity of the recipient and the plaintext are known, all operations with high computational complexity (such as exponential operations, pair operations, etc.) are pre-calculated to form offline ciphertext. In the online encryption phase, the rest of the encryption operations are calculated on the nodes after receiving the receiver's identity and plaintext. At the same time, optimize the bilinear pairing calculation algorithm in the encryption and decryption process, reduce the time complexity of the encryption process, and improve the data encryption transmission processing efficiency of the Internet of Vehicles.

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...
