description The invention provides an Internet of Vehicles privacy protection communication method based on a true random number, and the method mainly comprises the following steps: 1), carrying out the initialization of an authority center, and generating necessary parameters; 2) the vehicle performing registration application to the authority center to obtain important parameters; 3) encrypting the information by using a true random number generated by the vehicle-mounted power supply voltage and the obtained parameters, and uploading the information to a cloud server; and 4) other vehicles downloading the ciphertext from the cloud server and decrypt the ciphertext to obtain data. True random numbers not only have good statistical characteristics but also meet unpredictability, the true random numbers extracted on the basis of the vehicle-mounted power supply voltage are used as important parameters for generating the ciphertext and have very high safety, and a ciphertext attribute-based encryption scheme with an acce
