Abstract

The invention discloses a dynamic evaluation method and system for the information sensitivity of a smart power grid, and the method mainly comprises the following steps: firstly, considering the influence of a data objective information factor I, a power business operation environment C and business participant experience P on the information sensitivity of the smart power grid, and constructing a multi-dimensional measurement system for the business information sensitivity of the smart power grid; secondly, analyzing a multi-factor association mapping relationship among I, C and P, and proposing an information sensitivity dynamic measurement system under the influence of multiple factors of a power business scene; and finally, proposing a power business scene self-learning data sensitivity dynamic evaluation method, and adopting a dynamic feedback mechanism based on deep reinforcement learning to realize dynamic optimization of an information sensitivity evaluation model based on scene self-adaption. The invention has the beneficial effects that the evaluation of the information sensitivity is more universal and targeted, and the dynamic evaluation of the information sensitivity based on scene self-adaption is realized, so that the accuracy of the calculation of the information sensitivity of the intelligent power grid is improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and system for dynamically evaluating information sensitivity of a smart grid. Background technique [0002] With the increasing intelligence and interaction of smart grid terminal equipment and the increasingly diverse and complex network communication methods, the perception, transmission, sharing and utilization of smart grid business sensitive information such as three remotes and electricity collection are facing great security. Reliable challenges: First, in the smart grid environment, massive Internet of Things, relay protection, PMU equipment, etc. are spread all over the grid. They sense, monitor, and publish power business information such as grid equipment status, grid operation status, and market transaction status in real time. In the process of data transmission, sensitive information such as relevant business status information or control comm...
