Electric power wireless private network specific network attack monitoring method based on improved Apriori algorithm

Abstract

The invention discloses a specific network attack monitoring method for a power wireless private network based on an improved Apriori algorithm, so as to efficiently deal with the situation that the network attack of the power wireless private network frequently occurs in a power information physical environment. In a specific network attack scene of the power wireless private network, obtaining a specific network attack sample of the power wireless private network by utilizing a simulation platform, and mapping the sample into a Boolean matrix; an Apriori algorithm is improved, a Boolean matrix sample is trained by using the improved Apriori algorithm, abnormal items caused by network attacks are associated, and a specific network attack abnormal frequent item set of the power wireless private network is efficiently generated. Therefore, the specific network attack behavior in the power wireless private network is identified through the abnormal frequent item set of the specific network attack of the power wireless private network, the purpose of accurately monitoring the network attack in the power wireless private network can be achieved, and safe and stable operation of the power wireless private network is guaranteed.

Description

Technical field[0001]The present invention belongs to the field of power communication, and is specifically involved in an improved APRIORI algorithm based electrical wireless private network-attack monitoring method.Background technique[0002]With the development of information communication technology, the power system is no longer limited to the physical system, and the information and high integration of physical systems are implemented. The power system needs to sense the grid status through a large number of sensing units and communication networks. However, fiber optic communication, wireless public network has certain defects, resulting in the "last km" communication connection problem, and some business cannot be carried out. In 2016, the national network company coordinates the construction of the terminal communication access network and promoted the construction of electric wireless private network. The power wireless network has the advantages of low construction difficu...
