Internet of vehicles privacy protection communication method based on true random number

Abstract

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 access strategy hidden is designed to hide the attributes of the vehicle. And the effect of protecting the privacy of the vehicle is achieved.

Description

technical field [0001] The invention relates to intelligent networked vehicles, in-vehicle communication technology and cryptography, and in particular to the field of vehicle networking. Background technique [0002] With the integration of computer technology, network technology and the automobile industry, intelligent networked vehicles have become the focus of future competition. The continuous development of intelligent networked vehicles also means that we are entering the era of Internet of Vehicles. The integration of smart devices and wireless communication technology realizes the information interaction between vehicles and people, vehicles, roads and information network platforms, reduces the risk of accidents, improves traffic operation efficiency and provides a more comfortable driving environment. Although the Internet of Vehicles provides great convenience for intelligent transportation and our lives, it also faces severe challenges in information security. ...
