Problems solved by technology

[0003] In practical application, each vehicle in the same road section can communicate with each other through VANET and release road condition information, etc. However, how to evaluate the trustworthiness of the road condition information released by each vehicle and how to ensure the privacy of vehicle users when releasing road condition information is currently a problem. There is no effective solution in the prior art

Abstract

The invention provides a vehicle communication method based on a blockchain technology in a vehicular ad hoc network. The method comprises the steps as follows: a block chain in the vehicular ad hoc network is arranged for a road section, a vehicle in a road section acquires road condition information to be sent, and a trust value of the road condition information is acquired according to trustworthiness information of the vehicle; the vehicle packages the road condition information and the trust value of the road condition information into a block, and the blocks having the same road condition information in the same road section are connected to form one block chain by the vehicles; each vehicle in the road section downloads each block in the block chain, acquires the road condition information and the trust value of the road condition information in the block, and comprehensively judges the trustworthiness of the road condition information according to the trust value of the road condition information and related information of the block chain. According to the method provided by the invention, the user trustworthiness measurement mechanism, a message classification mechanism, a VANET block chain formation and extinction mechanism are combined, and safe and efficient authentication of the messages is achieved by using a VANET block chain technology under the premise of protecting user privacy.

Description

technical field [0001] The invention relates to the technical field of vehicle ad hoc network communication security, in particular to a vehicle communication method based on block chain technology in a vehicle ad hoc network. Background technique [0002] VANET (Vehicular Ad Hoc Networks, Vehicular Ad Hoc Networks) can provide vehicles with real-time road condition information and surrounding vehicle information (such as driving speed, driving direction, road section, emergency parking, etc.). The research and application of VANET will greatly facilitate the driver's perception of the surrounding driving environment, and play a very good role in the prevention of traffic accidents. Drivers can choose smoother road sections by knowing the information of the beyond-horizon range, and improve people's travel efficiency. [0003] In practical application, each vehicle in the same road section can communicate with each other through VANET and release road condition information,...
