Method for proving credible state data of Internet of Vehicles

Abstract

The invention provides an Internet of Vehicles credible state data proving method, which comprises the steps of collecting vehicle state data, signing the vehicle state data, packaging and sending the vehicle state data to a data processing platform of a vehicle enterprise; the data processing platform verifies whether the vehicle state data meets a preset condition, constructs a Merkle Tree for the data meeting the preset condition, stores all hash operation paths in the Merkle Tree, and broadcasts a data packet containing a Merkle Tree root hash value and signature information to all consensus nodes; writing the block into the block chain by using a consensus algorithm; and querying whether the root hash value is in the Merkle Tree leaf node parameters of the corresponding block according to the abstract value of the root hash value in the block chain, and if so, proving that the data is credible.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to a method for proving trusted state data of the Internet of Vehicles. Background technique [0002] With the modernization of transportation and the dramatic increase in the number of cars, vehicle accidents are also increasing. After a vehicle accident occurs, it is necessary to collect vehicle driving status data, etc., and determine the real cause of the vehicle accident according to the status data. Therefore, the authenticity of the status data is particularly important. [0003] In the prior art, the publication number CN111245966 A "A method for sharing information on the Internet of Vehicles based on the blockchain architecture" proposes an incentive method for sharing information on the Internet of Vehicles, which motivates cars to actively share information, and vehicle users can passively receive information from other vehicles. The reliability and aut...

[0003] In the prior art, Publication No. CN111245966 A "A Method for Sharing Information of the Internet of Vehicles Based on Blockchain Architecture" proposes an incentive method for information sharing of the Internet of Vehicles, which encourages cars to actively share information, and vehicle users can passively receive information from other vehicles, but The reliability and authenticity of the received information cannot be guaranteed, and the shared information still has the possibility of being tampered with or attacked

Publication number CN111464980 A "An Electronic Forensics Device and Forensics Method Based on Blockchain in the Internet of Vehicles Environment" proposes that the vehicle information is collected by the road test unit RSU, and the traffic control department and the RSU equipment are consensus nodes, saving data and writing it into the block In the chain, this design model puts the broadcast and consensus functions of block data into the RSU device, which seriously increases the workload of the RSU device. When the RSU device is installed on a large scale, the data processing speed of the RSU device will be slow and the network throughput will be slow. Serious problems such as insufficient
