ARCHITECTURE OF A SECURE INFORMATION SYSTEM BASED ON DISTRIBUTED LEDGER TECHNOLOGY: ECONOMIC ASPECTS

Abstract

This article examines the architecture of a secure information system built on distributed ledger technology. It substantiates the need to transition from a centralized data storage model to a distributed trusted environment that ensures cryptographic verification of transactions, immutability of records, and resistance to compromise of individual nodes. A multi-tiered system architecture is proposed, including subsystems for identification, access control, event registration, cryptographic protection, and anomaly monitoring. Particular attention was paid to aligning the designed model with the requirements of the Federal Service for Technical and Export Control of Russia for threat modeling and the provisions of GOST R 34.10-2012 on electronic digital signatures. An integrated security indicator was developed to assess the integrity, availability, and confidentiality of data.
