ENHANCING THE SECURITY OF INTERBANK PAYMENTS WITH, A COMPREHENSIVE CRYPTOGRAPHIC ARCHITECTURE

Abstract

In this article, the author discusses the problem of ensuring the security of electronic interbank payments in the context of growing cyber threats. Existing security systems, in particular SWIFT and SEPA, are analyzed and their limitations are identified. The purpose of this article is to develop a comprehensive cryptographic architecture that can significantly improve the security of electronic interbank payments by eliminating identified vulnerabilities and taking into account modern cyber threats. Methodology. The potential of integrated, systematic scientific approaches was used. Their combination allows for a comprehensive analysis of technical and pedagogical literature, including the study of monographic scientific publications and dissertation research covering the chosen topic. The scientific novelty lies in the development of a comprehensive cryptographic architecture based on encryption, authentication, intrusion detection, and security audit modules. Conclusions. The study found that modern interbank payment systems, such as SWIFT and SEPA, use a comprehensive approach to security, including organizational and technical measures. SWIFT uses asymmetric cryptography, hardware security modules, and two-factor authentication. SEPA uses EMV standards for card transactions and TLS/SSL protocols for online payments. It has been determined that to effectively counter modern cyber threats, a comprehensive cryptographic architecture for interbank payments is needed that meets strict requirements for security, performance, scalability, and interoperability. The author's proposed comprehensive security architecture for interbank payments consists of interconnected modules that provide multi-level protection. The modeling and experimental evaluation of the effectiveness of the proposed architecture was carried out, which confirmed its ability to provide a high level of security, performance and resistance to attacks.
