Abstract
En 中文
The microgrid faces increasingly severe communication security challenges due to its open and highly interactive characteristics. However, the traditional trust architecture cannot cope with the dynamically changing identity authentication requirements, and data transmission based on classical encryption is vulnerable to attacks from quantum computers. Existing quantum-secure microgrid research typically requires both parties to possess full quantum capabilities, which limits its practicality in real-world deployments. To address these challenges, this paper proposes a semi-quantum secure communication framework for microgrids. Firstly, a semi-quantum authentication model based on zero-trust architecture is introduced to support dynamic and secure identity verification between the microgrid central controller (MGCC) and distributed energy resources (DERs). Secondly, a semi-quantum key distribution (SQKD) scheme is integrated, requiring only the MGCC to be fully quantum-capable, thereby reducing system complexity. Additionally, a dynamic key provisioning strategy is designed based on DERs' energy characteristics to improve resource efficiency and system security. Experimental results and analysis provide valuable insights for the design and deployment of semi-quantum-enabled microgrid communication.
