A method for querying and verifying RSU data of Internet of Vehicles based on cloud platform

Abstract

The invention discloses a method for querying and verifying RSU data of the Internet of Vehicles based on a cloud platform, which includes the following steps: data collection and tree processing, data signature, data uploading to a cloud server, data evidence generation, data non-repudiation interaction, data verification and Interactive dispute arbitration. The data verification process in the present invention can efficiently use computing resources, especially when the signature is illegal, it can greatly reduce the meaningless computing cost, and introduce a trusted hidden party in the interaction stage between the cloud server and the client. The denial protocol solves the disputes caused by dishonesty between clients and Yuyun servers, so that clients cannot deny that they have received the corresponding services, and at the same time avoids the situation where cloud servers deny that they have provided wrong results to clients, thus ensuring The legitimate rights and interests of cloud servers and clients have been violated.

Description

technical field [0001] The invention relates to the field of RSU data outsourcing of the Internet of Vehicles, in particular to a method for querying and verifying RSU data of the Internet of Vehicles based on a cloud platform. Background technique [0002] The Internet of Vehicles is a major trend in the development of modern intelligent transportation technology. The RSU of the Vehicle Network can collect vehicle information within its coverage area, including speed, on-board items, and vehicle identity. Car owners in the Internet of Vehicles can obtain vehicle information with specific characteristics through RSUs in different locations, and the identity information and location information of RSUs are often related to each other, which makes the identity information of RSUs the key information associated with the identity of the characteristic vehicle. Therefore, the owner of the vehicle can obtain the trajectory of the vehicle based on the identity information of the RS...

AI Technical Summary

Problems solved by technology

In addition, with the development of transportation, the data collected by RSU is becoming more and more abundant, and the types of services required by car owners are becoming more and more complex. RSU cannot provide fast and reliable services. Therefore, it is an inevitable development trend in the future for RSU to outsource data to cloud servers. The cloud server provides services to the client, but the cloud server is untrustworthy, and there are problems such as data tampering, loss and forgery

In addition, there are disputes such as dishonest interactions between cloud servers and clients:

[0003] (1) Privacy disclosure: When the client submits vehicle identity-based query requests to the cloud server at different time periods, if the cloud server discloses the identity information of the vehicle information provider RSU to the client, the client can pass the vehicle identity information at different times. The RSU identity information infers the trajectory of the vehicle, and the combination of the trajectory of the vehicle and the identity of the vehicle is equivalent to the whereabouts of the owner, which has become a serious privacy leak problem;

[0004] (2) Data tampering, loss and forgery: the data provided by the cloud server may be maliciously tampered with, lost or forged

In addition, in order to save query costs and storage costs, the cloud server will also forge or tamper with query results.

This does not guarantee data authenticity and integrity;

[0005] (3) The problem of dishonesty: In practical applications, both the cloud server and the client are dishonest

Therefore, the data verification scheme based on the data flow sliding window query cannot solve the data verification problem in the data outsourcing of the Internet of Vehicles, and there is no reliable mechanism to protect the legitimate rights and interests of the cloud server and the client
