Research on Secure Access of 5G Heterogeneous Terminals in the Coal Industry Based on Identity Authentication Technology

The wide connectivity capability of 5G networks supports massive, heterogeneous, and customized terminal access, but the terminal types are complex and diverse, and the terminal devices are scattered and difficult to manage uniformly. The differences in terminal security capabilities are huge, and the application requirements are complex and difficult to deploy strong security protection. This poses many challenges to identity authentication and seriously threatens the secure and stable operation of information systems. This article focuses on the security risks faced by terminal devices accessing the business private network in the coal industry's 5G private network. It analyzes and studies the security risks and hidden dangers of device access to the business private network, with a particular emphasis on the study of 5G heterogeneous terminals in the coal industry. It proposes a secure application scheme for identity authentication technology for heterogeneous terminals that integrate multiple identity authentication technologies in the coal industry, greatly improving the security technology level of 5G terminals in the coal industry and enhancing network security protection capabilities.
