The purpose of the study: is to develop an information protection model for analyzing the constructive security of the distributed registry architecture, taking into account the access control policy and the quantum threat. Research methods: object-oriented analysis of complex systems, system analysis, theory of modular cluster networks, graph theory, matrix theory, mathematical logic. Research result: an extended information protection model with full overlap for distributed registry systems has been developed, taking into account the influence of the quantum threat, which allows evaluating constructive protection and conducting formal static or dynamic security analysis of the architecture.Scientific novelty: based on the methods of the theory of modular cluster networks, an extended information protection model with full overlap has been developed to analyze the constructive security of a distributed registry due to the cluster decomposition of architecture and information interactions, taking into account the effectiveness of information security tools. The system criteria for evaluating constructive protection are shown. The results were obtained with the financial support of the project «Technologies for countering previously unknown quantum cyber threats», implemented within the framework of the state program of the «Sirius» Federal Territory «Scientific and technological development of the «Sirius» Federal Territory (Agreement No. 23-03 dated September 27, 2024).
