Multi-energy equipment digital twin data stream communication authority management method and system

Abstract

The invention discloses a multi-energy equipment digital twin data flow communication authority management method and system. The method comprises the following steps: a server generates a unique authority code containing the above information by using an encryption algorithm according to the ID of a request terminal, the ID of request data, an authority type and an authority parameter; a data stream interaction channel between the terminal and the request data is established by utilizing the unique permission code; and the authority of the data stream communication is regularly checked basedon the channel by using a broadcast detection mechanism, and the data stream interaction channel with expired and illegal authority is continuously cleaned out, thereby realizing a data stream communication management function. According to the invention, the management is more scientific, the algorithm is clearer, more efficient and safer, and the hierarchy is clearer; the channel resource utilization rate is improved; the blank of a multi-energy equipment-oriented digital twin data stream communication authority management algorithm and system at the present stage is filled; and the requirement of multi-service application for data flow interaction can be met, and real-time mapping of a physical entity and a virtual mirror image is guaranteed.

Description

technical field [0001] The invention relates to the technical field of data stream communication authority management, in particular to a method and system for multi-energy device digital twin data stream communication authority management. Background technique [0002] At present, the authority management of data flow communication in the power system mainly focuses on the authority management and access control technology research for the integrated power communication management system. Traditional access control methods mainly include autonomous access control, mandatory access control, attribute-based access control, and role-based access control. The above four control methods can manage communication permissions through direct user authorization; the subject of autonomous access control can Grant its own power to other subjects, but its resource consumption is seriously unsuitable for large and complex systems; Mandatory access control implements multi-level access co...

Traditional access control methods mainly include autonomous access control, mandatory access control, attribute-based access control, and role-based access control. The above four control methods can manage communication permissions through direct user authorization; the subject of autonomous access control can Grant its own power to other subjects, but its resource consumption is seriously unsuitable for large and complex systems; Mandatory access control implements multi-level access control according to the access control policy formulated by the system, but the rules formulated have poor flexibility and low application rate; Attribute-based access control permissions are authorized through user attributes and are not directly assigned to users. It has the advantages of supporting large-scale complex systems and high flexibility, but the process is cumbersome and difficult to manage; role-based access control assigns roles to users. Allowing users to access different permissions according to different roles is easy to manage and has high flexibility. Therefore, it is suitable for access control of resource interaction between different businesses. However, when the number of system services is large and the permissions change frequently, the traditional permission control method will become very complicated
