The invention provides an Internet of Vehicles data sharing method and system, and the method comprises the steps: carrying out the identity reputation verification of a vehicle through a roadside unit based on a reputation record chain; after the verification is passed, based on the traffic data chain, recording traffic data of the vehicle through a processing unit; after the data is used, reputation records are evaluated and stored based on the chain of reputation records. Visibly, the method and the system can decouple the traffic data and the reputation record in an account book multi-chain parallel mode, so that the historical data can be correspondingly pruned in a mode of reserving the block head and deleting the block body content, and the effect of reducing the storage pressure is achieved; meanwhile, a reputation mechanism represented by identity reputation verification can identify malicious vehicles, so that addition of malicious data is avoided, data quality is improved, and fairness is guaranteed. In addition, the roadside unit can also improve the traditional PBFT through a consensus mechanism, so that the roadside unit can bear nodes in a larger scale, and the expandability can be further improved.

    本申请提供一种车联网数据共享方法及系统,该方法包括:基于信誉记录链,通过路边单元对车辆进行身份信誉验证;在验证通过后,基于交通数据链,通过处理单元记录该车辆的交通数据;在数据被使用后,基于信誉记录链,评估并存储信誉记录。可见,该方法及系统能够通过账本多链并行的方式将交通数据和信誉记录解耦,以此来使得历史数据可以通过保留区块头、删除区块体内容的方式进行相应的修剪,从而实现降低存储压力的效果;同时,身份信誉验证所代表的信誉机制能够对恶意车辆进行鉴别,从而避免恶意数据的加入,并提升数据质量,进而使得公平性得到保证。另外,路边单元还能够通过共识机制对传统PBFT进行改进,从而使其能够承载更大规模的节点,进而还能够对可扩展性进行提升。
