铁路5G-R网络安全技术研究

Research on Railway 5G-R Network Security Technology

5G-R网络即将进入建设阶段,且铁路专网涉及行车安全,对网络安全要求极高,亟须对5G-R网络安全开展研究。为全面提升5G-R端到端安全防护水平,通过总结GSM-R网络的安全要求,分析5G-R网络面临的安全风险和安全需求,提出5G-R网络安全体系架构;从5G-R基础设施安全、终端接入安全、组网安全、运维安全、数据安全和网络边界安全等方面阐述安全技术方案,并提出通过5G-R安全态势感知系统,实现从5G-R系统基础安全技术到系统内生安全能力全面提升的方案。

The 5G-R network is on the verge of entering the construction stage.Given that the private network for railways is closely linked to train operation safety,there are extremely high requirements for network security.As a result,there is an urgent need to conduct research on 5G-R network security.To comprehensively enhance the end-to-end security protection of the 5G-R network,this study summarized the security requirements of the GSM-R network,analyzed the security risks and requirements faced by the 5G-R network,and proposed an overall 5G-R network security architecture.The security technical schemes were detailed from various aspects:5G-R infrastructure security,terminal access security,networking security,operation and maintenance security,data security,and network boundary security.Additionally,the study proposed leveraging the 5G-R security situational awareness system to achieve a comprehensive upgrade from basic security technologies to endogenous security capabilities within the 5G-R system.
