Embodiment Construction
[0026] The present invention considers that if the structure mode related to the power information system network is not specially protected, some important information data of the power information system network may be found by reasoning due to the regularity of the transmitted related data. Based on this, the basis for discovering important information data through reasoning lies in the development of link prediction technology. If the regularity of network structure can be accurately quantified through prediction algorithms and the weak areas of power data protection can be detected, it can protect the privacy of power information system networks. provide a stronger guarantee.
[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are o...

The invention belongs to the field of electric power information transmission, and specifically relates to a key information transmission link identification method of an electric power information network. rank decomposition; seek the number k of potential features of the power information network; obtain multiple non-negative decomposition matrices W and H; calculate through multiple non-negative decomposition matrices W and H to obtain the similarity matrix of multiple graph links; Multiple similarity matrices are superimposed to obtain the final similarity matrix, and the similarity score of each link in the final similarity matrix is calculated to determine the key information transmission link; the present invention reduces power consumption by constructing a power information network diagram. The complexity of the information network transmission link, and the effective link prediction method is used to detect the power data transmission link.
Description
technical field [0001] The invention belongs to the field of electric power information transmission, and in particular relates to a method and a system for identifying a transmission link of key information of an electric power information network. Background technique [0002] With the development of computer network technology, the dependence of the power system on the network is gradually increasing, and the computer network has become an important part of our work. Electricity MIS system, electric power marketing system, electric energy billing system, SAP system, electric power ISP business, operating financial system, human resource system, etc., it can be said that the current integration of electric power resources has completely relied on the computer system to manage. While enjoying the convenience of computers, the security of power data is also threatened. Hackers invade the power information system arbitrarily, which will lead to slower network information tran...
