Abstract

As the power system undergoes continuous digitization and networking, the associated network security challenges have become increasingly prominent. Addressing these issues, the zero trust framework emerges as a cutting-edge security concept that underscores sustained vigilance toward users, devices, and applications within the network environment. Its core principle involves minimizing the scope of trust granted to the smallest possible extent. This study delves into the application of the zero trust framework in crafting the architecture of power system networks, with the primary objective of enhancing network security and thwarting potential threats. The article commences by scrutinizing the network security requirements of internet applications and subsequently proposes a zero trust architecture as a security solution. The construction of a zero trust-based smart grid security protection architecture follows, encompassing elements such as terminal trusted perception agents, multi-source data aggregation platforms, intelligent trust evaluation platforms, dynamic access control platforms, and trusted access agents. Finally, the efficacy of the zero trust framework in power system network architecture is validated through case studies and simulation experiments. The research findings highlight a significant enhancement in the network security of the power system with the incorporation of the zero trust framework. This, in turn, establishes an effective security mechanism conducive to the digital transformation of future power systems. In summary, the study contributes a novel security approach and technical solution for the design of power system network architecture, offering valuable insights and reference for the development of the power system network security field.
