摘要
文章从车联网中车载终端高速移动、频繁跨域的特征出发,分析了车联网环境下跨域身份认证面临的安全威胁,提出了一种基于区块链的车联网跨域认证体系及方案。方案以联盟链架构和“授权机构-计算服务-路测单元”域网络为基本模型,详细介绍了移动终端在初次入网和后续跨域时的身份认证协议。相比于传统认证方案,该协议在通信开销和计算复杂性方面均有所优化,且具备防泄露、隐私性、可监管等安全属性。
Based on the characteristics of high-speed and frequent cross-domain mobility of on-board terminals in the Internet of vehicles,this paper analyzes the security threats faced by cross-domain identity authentication in the Internet of vehicles environment,and proposes a cross-domain authentication system and scheme based on blockchain for Internet of vehicles.The scheme takes the alliance chain architecture and the domain network of"Trusted Authority-Computing Services-Road-Test unit"as the basic model,and introduces the identity authentication protocol in detail when the mobile terminal enters the network for the first time and the subsequent cross-domain.Compared with the traditional authentication scheme,the protocol is optimized in terms of communication overhead and computing complexity,and has security attributes such as disclosure prevention,privacy,and supervision.
