The article discusses aspects of information security when deploying an authorization subsystem based on OAuth 2.0 protocol in a distributed energy management system with a microservice architecture. The main disadvantages of the existing methods of authorization and authentication in client-server systems are determined. An example of use and implementation of authorization and authentication mechanisms based on OAuth 2.0 protocol is given. The authorization scheme using web calls is considered in detail. Use of such a scheme makes it possible to increase the flexibility of energy management programs. Experimental studies of the offered implementation based on OAuth 2.0 protocol have been carried out. The study results indicate a slight increase in authorization and authentication times. Conclusions about the effectiveness of the implemented authorization scheme between subsystems in the distributed system with the microservice architecture are made. [ABSTRACT FROM AUTHOR]

The article deals with the main tasks of energy management systems, as well as automation of the processes of energy management systems. The problem of intellectual verification of data entered by users in the energy declarations of buildings is considered. To solve the problem, a multilayer binary classifier was developed. The paper presents the results of testing the effectiveness of the developed classifier, as well as data on the training of such a classifier. The data set is described, as well as the results of testing the classifier. An assessment of the classification of the developed approach was made. The classification accuracy was 99.7%. A scheme for the implementation of the developed classifier is proposed. [ABSTRACT FROM AUTHOR]
