Расширенное использование централизованных студенческих информационных систем (Student Information Systems, SIS) в условиях цифровизации высшего образования увеличивает риск несанкционированного изменения данных студентов, поскольку ввод и управление данными зависят от одного административного доверенного домена. В данной работе представлена разработка и экспериментальная проверка архитектуры технологии распределенного реестра (Distributed Ledger Technology, DLT), предназначенной для обеспечения криптографически проверяемой целостности экзаменационных результатов. Предложенная архитектура основана на интеграции SQL-ориентированной SIS и блокчейн-системы Hyperledger Fabric через защищенный middleware-слой. Экзаменационные записи SIS преобразуются в криптографическое hashcommitment и сохраняются в неизменяемом ledger. Экспериментальная проверка проводилась путем развертывания реальной сети Hyperledger Fabric в контейнеризированной среде и тестирования с использованием Hyperledger Caliper при нагрузке до 120,000 транзакций. Основными показателями были пропускная способность, задержка фиксации, способность обнаружения нарушений целостности данных и характеристики хранения реестра. Архитектура достигла пропускной способности 728 транзакций/секунду и максимальной пропускной способности 842 транзакции/секунду при средней задержке фиксации менее 2.0 секунд. Тесты на несанкционированное вмешательство показали успешное обнаружение всех несанкционированных изменений со средним временем обнаружения 19.8 мс. Анализ хранения показал линейный рост реестра и потребность менее 5.68 ГБ за десять лет. Результаты демонстрируют, что предложенная архитектура устраняет единую точку отказа, присущую централизованным системам, и обеспечивает масштабируемую криптографически проверяемую целостность академических записей.

The increasing use of centralised Student Information Systems (SIS) as part of the digitalisation of higher education has led to these systems being used despite the risk of unauthorised alteration of student data due to reliance of data entry and administration on one administrative trust domain. This paper presents the design and experimental validation of a Distributed Ledger Technology (DLT) architecture to provide verifiable integrity of examination results. The proposed architecture is based on a combination of an SQL-based SIS and a Hyperledger Fabric Blockchain via a secure middleware layer. Examination records in the SIS are converted to a cryptographic hash commitment and stored on an immutable ledger. Experimental validation was carried out by deploying a Hyperledger Fabric Network in a containerized environment and testing it using Hyperledger Caliper at workload levels up to 120,000 transactions. Key performance metrics were throughput, commit latency, ability to detect violations of data integrity and storage characteristics of the ledger. The proposed architecture achieved throughput of 728 transactions/second and maximum throughput of 842 transactions/second with average commit latency less than 2.0 seconds. Tampering tests were performed to verify the architecture’s ability to detect unauthorised changes and it successfully detected all unauthorised changes with average detection time of 19.8ms. Analysis of storage requirements showed that the ledger grew linearly and would require less than 5.68 GB over ten years. The results demonstrate that the proposed architecture eliminates the single point of failure in centralized systems and provides scalable, cryptographically verifiable academic record integrity.
