基于区块链的车联网身份验证研究

Research Progress on Authentication of Internet of Vehicles Based on Blockchain

随着5G和车联网技术发展,车辆作为接入车联网第一道防线的重要组成部分,其身份验证是车联网中需要解决的重要问题,已引起了国内外众多学者的关注。随着区块链技术的不断完善,为解决车联网身份验证问题提供了新的思路。作为一种去中心化、匿名化、不可篡改的分布式账本技术,区块链已应用在越来越多的技术和行业上,尤其在车联网身份验证方面已取得一些研究成果。本文简要介绍了车联网和区块链的背景知识;然后,按车联网身份验证过程中用到的区块链方案,分别从公有链、私有链、联盟链三个方向对车联网身份验证解决方案进行讨论;最后,总结了车联网身份验证方案及未来可进一步研究的方向。

With the development of 5G and Telematics,the vehicle,as an important part of the first line of defense to access Telematics,its identity verification is an important problem to be solved in Telematics,which has attracted the attention of many scholars at home and abroad.With the continuous improvement of blockchain technology,it provides a new idea to solve the problem of identity verification in Telematics.As a decentralized,anonymous and tamper-evident distributed ledger technology,blockchain has been applied to more and more technologies and industries,and some research results have been achieved especially in Telematics identity verification.This article briefly introduces the background knowledge of Telematics and Blockchain.Then,the Telematics identity verification solutions are discussed in three directions:public chain,private chain and federated chain,respectively,according to the blockchain solutions used in the Telematics identity verification process.Finally,the future directions of Telematics identity verification solutions are summarized for further research.
