Vehicle path planning method with privacy protection

Abstract

The invention discloses a vehicle path planning method with privacy protection, and the method comprises the steps: an initialization stage: a certification authority constructs related information of a roadside unit, and generates and issues related safety parameters; a registration stage which is used for verifying the identity of the vehicle before entering the system; a query stage, in which path planning is carried out on the vehicle, and required roadside unit information is acquired from a certification authority. Path planning with privacy protection is realized by using BGN homomorphic encryption, so that the path information planned in advance is not leaked when the vehicle acquires the roadside unit information from the authentication authority, the privacy security of the vehicle is effectively protected, and the authentication efficiency of the vehicle and the roadside unit is greatly improved.

Description

technical field

[0001] The invention relates to the fields of intelligent transportation and the Internet of Things, in particular to a privacy-protective vehicle route planning method. Background technique

[0002] The application of Internet of Vehicles technology can significantly improve the efficiency and safety of the transportation system, and can effectively reduce traffic accidents and reduce safety risks. Most of the current Internet of Vehicles authentication schemes are designed for real-time authentication of vehicles and roadside units (RSUs), and do not involve the path planning of vehicles. The car has been driven far away, and this efficiency is unsatisfactory. The important thing is that in terms of protecting user privacy, many schemes use differential privacy, which is effective for hiding a certain location point, but for the entire path, it is unreliable to use differential noise addition. If the route planning for the vehicle can be carried out in ad...
