摘  要:车联网大数据时代的兴起,信任问题已经成为大数据面临的最大问题,它对数据安全流通和车联网产业发展造成影响.以区块链作为数据共享的平台是当下研究的热点,在车联网中发挥着重要作用.结合区块链及雾计算服务器更好地实现车辆私有数据的存储和共享问题,同时为保证数据的可靠性及减少车辆与被授权的第三方组织和个人共享数据时的频繁交互,结合无证书代理签密技术,本文提出一个基于区块链的车联网数据共享模型.通过分析发现,该模型不仅在通信开销与算力方面耗能较少,而且在安全性上有良好的表现,具有可靠的实现性.With the rise of the Internet of Vehicles big data era,the issue of trust has become the biggest problem facing big data,which has an impact on the safe circulation of data and the development of the Internet of Vehicles industry.Using blockchain and vehicular fog node servers to better realize the storage and sharing of vehicle private data.At the same time,to ensure the reliability of data and reduce the frequent interactions between vehicles and authorized third-party organizations and individuals when sharing data,combined with no certificateless proxy signcryption,this article proposes a data sharing model for the Internet of Vehicles based on blockchain.Through the analysis,it is found that the model not only consumes less energy in terms of communication overhead and computing power,but also has good performance in security and reliable implementation.
