Quantum Resistant Security Product Frameworks for Future Fintech Infrastructure

Abstract

The rapid advancement of quantum computing presents a fundamental challenge to the cryptographic foundations underpinning modern fintech infrastructure. Financial systems rely extensively on public-key cryptography for authentication, confidentiality, integrity, and non-repudiation across payments, digital banking, blockchAIn platforms, and regulatory reporting systems. Quantum algorithms, particularly shor’s and grover’s algorithms, threaten to render widely deployed cryptographic schemes insecure, creating long-term systemic risk for financial data and digital trust. This paper examines the design of quantum-resistant security product frameworks tAIlored for future fintech infrastructure. It analyzes the cryptographic, architectural, and governance implications of post-quantum security adoption in highly regulated, cloud-native financial environments. Through architectural synthesis, threat modeling, and expert-informed analysis, the study proposes a quantum-resistant fintech security framework that integrates post-quantum cryptography, crypto-agility, hybrid security architectures, and compliance-aware migration strategies. The findings demonstrate that proactive adoption of quantum-resistant security frameworks enables fintech organizations to mitigate long-term cryptographic risk while maintaining performance, interoperability, and regulatory assurance. The paper positions quantum-resistant security not as a speculative research concern, but as a strategic product-level imperative for sustaining trust and resilience in future digital financial ecosystems.
