Abstract
The invention provides an electric power Internet of Things information security risk assessment method and device. The method comprises the steps of utilizing a gene expression programming algorithmto calculate the weight of each assessment index in a pre-constructed risk assessment index system; determining a comprehensive evaluation matrix based on the membership degree of each evaluation index to each risk level; and evaluating the information security risk of the power Internet-of-things based on the weight and the comprehensive evaluation matrix. The evaluation process is simplified, the weight is calculated by adopting a gene expression programming algorithm, the determination of the weight is objective and accurate, the information security risk of the electric power Internet-of-things is evaluated based on the weight and the comprehensive evaluation matrix, the relationship of each evaluation index in the risk evaluation index system is considered, and the accuracy of the evaluation result is greatly improved; in consideration of a large number of factors influencing safe and stable operation of the electric power Internet-of-things, relatively high correlation between the factors and non-additivity between the influence factors, the reliability and stability of safe operation of the electric power Internet-of-things are improved.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to a method and device for assessing information security risks of the electric power Internet of Things. Background technique [0002] In recent years, with the deterioration of the environment and the increase in the demand for energy supply reliability, a more efficient, green, and reliable power system is particularly important. The integrated power system has a good development prospect because it can integrate multiple energy forms, improve energy efficiency, and reduce energy costs. Therefore, it is very important to ensure the safe, stable and effective operation of the integrated power system with the power Internet of Things as the core. However, as more and more energy loads are incorporated into the power grid communication system of the power Internet of Things, the scheduling and operation of the power Internet of Things is more difficult, and it is easy ...
