轨道交通"四网融合"分布式身份认证技术研究
Research on Distributed Identity Authentication Technology of Rail Transit
内容近年来，我国城市群和都市圈呈现快速发展态势，轨道交通"四网融合"网络化发展趋势迫在眉睫，其中身份认证就是保护数据安全的第一道防线。目前轨道交通各系统仍停留在传统身份认证阶段，难以满足"四网融合"形势下跨系统认证，频繁交互的需求。文中提出了适用轨道交通系统的基于联盟区块链技术的轨道交通分布式数字身份认证体系，设计了适用于轨道交通系统的联盟数字身份，从体系结构、身份控制、凭证管理以及隐私安全的角度阐述了该系统的运行模式，完成了数字身份的全周期身份管理，为轨道交通"四网融合"提供了合理便捷的分布式身份认证技术，为后续融合发展提供了解决思路。

In recent years, China\'s urban agglomerations and metropolitan areas have shown a rapid development trend, and the development trend of "four-network integration" network of rail transit is imminent, of which identity authentication is the first line of defense to protect data security. At present, the rail transit systems are still in the traditional identity authentication stage, which is difficult to meet the needs of cross-system authentication and frequent interaction under the situation of "four-network integration". In this paper, a distributed digital identity authentication system for rail tResearch on Distributed Identity AuthenticResearch on Distributed Identity Authentication Technology of "four-Network Integration" of Rail Transitation Technology of "our-Network Integration" of Rail Transitransit based on consortium blockchain technology is proposed for rail transit system, an alliance digital identity suitable for rail transit system is designed, and the operation mode of the system is elaborated from the perspectives of architecture, identity control, credential management and privacy security, which completes the full-cycle identity management of digital identity and provides a reasonable and convenient distributed identity authentication technology for rail transit "four-network integration", which provides a solution for subsequent integration and development.
