description 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 efficie
