Problems solved by technology

Due to the complexity of smart grid information integration, there will be the following defects in the security of using the existing access control technology directly in the smart grid: (1) At present, most of the application systems use role-based access control (RBAC ) model access control technology, but RBAC is insufficient in the security of cross-domain access
However, the division of attributes is more complicated, and the impact of the role's environment (such as physical location, network location, etc.) on access control is not considered.
(3) Behavior-based access control integrates relevant information such as roles, temporal states, and environmental states, and can flexibly handle various access control issues. However, the constraints and management strategies among roles, temporal states, and environments need to be further developed Research
(4) There are two types of context-related access control: location-based access control and temporal-based access control. This type of access control technology can determine which users are valid according to the user's current location or temporal constraints, and It can achieve space responsibility isolation restrictions, location-based timing restrictions, etc., but the interaction of various factors needs further study

Abstract

The invention discloses an access credibility and rapid permission assignment based smart power grid access control method. The method comprises that a smart power grid system is deployed; a smart power grid dispatching center is in charge of distributing power to a data control center according to actual needs of a smart power grid data control center; a detection and authentication module of the smart power grid data control center sends detection and authentication information to a credibility computation module after access authentication is completed, the credibility computation module performs credibility computation processing on the detection and authentication information and transmits credibility computation results to an access granularity distribution module, and the access granularity distribution module performs fine granularity distribution according to the credibility computation results and performs mapping with a common permission set computation module and an advanced permission distribution module to obtain a final access permission range. According to the method, the credibility computation module is arranged, so that internal resources are prevented from being accessed illegally, and the system access safety is guaranteed. By means of the arranging of the common permission set computation module, the power grid permission distribution efficiency is improved on the premise that the safety is guaranteed.

Description

technical field [0001] The invention belongs to the field of access control, and relates to terminal access trust degree calculation and user authority distribution in a smart grid, in particular to a smart grid user access authorization method. Background technique [0002] In today's world, gradually replacing fossil energy with renewable energy, building an innovative system of energy use, completely transforming the existing energy utilization system with information technology, and maximizing the energy efficiency of the power grid system are the challenges of energy development in various countries. Therefore, the smart grid came into being. The idea of ​​the smart grid is to develop, transport, store, convert (power generation), transmit, distribute, supply, sell, service, and store energy resources with various electrical equipment and other energy consumption of energy end users through a communication network. The facilities are connected together to achieve preci...
