Sucurity Protection Framework for Power 5G Services Based on Zero-Trust Model

The Energy Internet is one of the core components of the Industrial Internet, with trillions of terminals connected to the network, linking all aspects of energy production, transmission and consumption online, and generating massive amounts of data for comprehensive awareness. The traditional security architecture is based on “defense in depth + boundary protection”. However, with the development of the Energy Internet, the security boundary is gradually broken and completely blurred, and the boundary-based security protection system gradually fails to meet the security needs of the Energy Internet. This paper proposes a zero-trust based adaptable security protection framework for Power services, which uses differentiated slicing to achieve security isolation for Power services, low latency for Power services through UPF sinking and FlexE, flexible and adjustable zero-trust security management through exposure security capability. The framework can achieve the low latency and high security requirements of terminal access under the power 5G network, and provide communication reliability for the ‘last mile’ of the smart power loT.
