摘要
车联网中实现高效、安全的共享数据对智慧交通的发展具有重要意义。将区块链技术与车联网相结合,在促进车联网数据共享和隐私保护改善方面都有巨大的潜力,但仍然存在区块链技术如何保证车联网数据安全共享的问题。针对这一问题,对区块链和车联网技术融合的最新研究与车联网数据共享的应用进行了系统的整理和分析。首先,总结归纳传统车联网数据共享模型并分析其特点;其次,从共享数据可靠性、共享数据安全性、激励机制、访问控制、可扩展性和储存方式六方面介绍基于区块链的车联网数据安全共享现状;再次,列举并分析三种基于区块链的车联网数据安全共享的通用模型的特点;最后,讨论了该领域未来研究发展的方向,并对解决车联网中数据共享安全问题提出解决思路,为构建未来车联网数据共享提供理论支持。
Efficiently and safely sharing data in the Internet of vehicles(IOV)is of great significance to the develop-ment of intelligent transportation.To combine with blockchain has great potential in promoting the extent of sharing and privacy for IOV,however,there still exists a problem how to ensure its safety.From the perspective of solving the problem,this paper systematically arranges and analyzes the latest researches on the integration and implemen-tation of blockchain of data sharing with IOV.Firstly,it summarizes the traditional vehicle networking data sharing model and analyzes its characteristics.Secondly,it introduces the current situation of data secure sharing of IOV based on blockchain from six aspects,including the reliability of sharing data,the security of sharing data,incentive mechanism,access control,scalability and storage mode.Thirdly,it lists and analyzes the characteristics of three general models for secure data sharing of IOV based on blockchain.Finally,it discusses the directions of future re-search and the development of this field,and presents feasible solutions to solve the security problem of data sharing in IOV,so as to provide theoretical support for the construction of data sharing in the future Internet of vehicles.
