Abstract

The article investigates methods for ensuring the long-term validation of electronic signatures in modern electronic document management systems and archives. It analyzes the problems of signature validity loss over time, specifically due to certificate expiration, the unavailability of certificate status checking services, and the loss of robustness in cryptographic algorithms. Standards and mechanisms for long-term preservation are examined. An approach to building LTV (Long-Term Validation) systems is proposed, considering the requirements for the long-term preservation of electronic documents.
