A security situation awareness and prediction method for power communication network based on irt hierarchy analysis and lstm

Abstract

The invention discloses a power communication network security situation awareness and prediction method based on IRT hierarchical analysis and LSTM (Long Short Term Memory). The method is used for solving awareness and prediction on the security situation in the existing power communication network. The method comprises the implementation processes of: firstly, extracting characteristics influencing network security situation evaluation from network connection condition data acquired in the power communication network, furthermore, calculating a network security situation value based on a hierarchical IRT model, and then, establishing a network security situation prediction model based on LSTM, so that prediction on the security situation of the power communication network is realized. Byadoption of the method disclosed by the invention, the accuracy of the importance weight in a security situation evaluation process can be effectively improved; for the time sequence properties of anetwork security situation, the security situation of the power communication network can be predicted better; and furthermore, the network security condition can be reflected and predicted more accurately and effectively through the established model evaluation and prediction method.
