Abstract

The evolution of digital banking has created an increasingly complex network infrastructure connecting geographically distributed bank branches, requiring robust security protocols to protect sensitive financial data during transmission. Traditional inter-branch communication systems predominantly rely on Transport Layer Security (TLS) and Virtual Private Networks (VPNs), which face emerging threats from quantum computing advancements and sophisticated cyberattacks. This research addresses the critical gap in current banking security infrastructure by developing a novel quantum-resistant communication protocol specifically designed for inter-branch connectivity. The protocol integrates advanced cryptographic techniques with behavioral analytics to create a comprehensive security framework that anticipates future threats while addressing current vulnerabilities. Our research establishes three primary objectives: first, to design a quantum-resistant cryptographic framework that maintains security against both classical and quantum computing threats; second, to develop an efficient key management system that minimizes operational overhead while maximizing security; and third, to integrate behavioral biometric authentication to enhance identity verification across distributed banking nodes.
