Multi-dimensional Trusted Authentication System for Electricity Market Based on permission Hierarchy Classification

With the development and business expansion of the electric power market, the categories and number of market subjects are increasing, and the complexity of authority management is improving, which puts forward higher requirements for the quality and stability of electronic authentication services. This paper proposes a multi-dimensional trusted authentication method for the electricity market based on hierarchical classification of authority. Firstly, a unified authority hierarchical classification system for power trading users is constructed based on the improved RBAC model, and the user authority is instantiated in the model. Secondly, a trusted authentication system for the power market is designed to ensure that users perform operations with the correct permissions, and the identity authentication process of power market subjects logging into the platform is implemented. Finally, the efficiency of the method is demonstrated through comparative simulation experiments.
