Research on 5G-based Disaster-Resistant Security for Smart Power Grids

In the 5G era, smart power grids necessitate robust cybersecurity measures. This paper delineates a 5G private network designed for disaster recovery, which includes features such as multi-dimensional terminal access, secondary authentication, and zero-trust dynamic authentication to safeguard the power infrastructure. It incorporates advanced encryption and authentication protocols to ensure data integrity, and utilizes network isolation and disaster recovery mechanisms to maintain continuous grid operation. The system standardizes authentication for heterogeneous terminals and transitions from CT to IT-driven identity verification, thereby enhancing the grid's resilience against cyber threats. This research supports the digital transformation of the power industry by reinforcing its security posture.
