Development and Implementation of a Quantum-Resistant Cryptographic Agility Framework Using CRYSTALS-Kyber and Blockchain-Based Key Exchange for Financial Infrastructure Security

Résumé

This study investigates how integrating quantum-resistant cryptographic frameworks, specifically CRYSTALS-Kyber a lattice-based post-quantum encryption scheme and blockchain-based key exchange can enhance the security and resilience of financial infrastructures facing emerging quantum threats. Building on Gbadebo’s (2025) agility framework, this research proposes a four-layer cryptographic agility model encompassing governance, infrastructure adaptability, algorithm management, and operational readiness. By leveraging data from the NIST PQC finalists, the 2024 Verizon Data Breach Investigations Report, and ENISA threat assessments, the study applies bibliometric analysis, statistical testing, and Failure Mode and Effects Analysis (FMEA) to evaluate both the benefits and challenges of adopting post-quantum cryptography (PQC) alongside blockchain technologies. Findings indicate that financial institutions integrating blockchain experience reduced breach frequencies and financial losses, while key management complexity emerges as a critical challenge requiring strategic attention. To guide adoption, the study introduces an eight-phase implementation roadmap supporting seamless migration from classical to quantum-resistant systems, ensuring compliance with evolving regulatory standards and enhancing operational continuity. Recommendations include enforcing sector-wide PQC adoption timelines, prioritizing investment in cryptographic agility, providing targeted upskilling programs for technical staff, and fostering robust public-private collaborations to accelerate quantum resilience efforts. By bridging theoretical insights with empirical analysis, this research provides actionable guidance for policymakers, cybersecurity professionals, and financial institutions seeking to proactively fortify their infrastructures against imminent quantum-enabled threats and secure long-term data integrity in an evolving threat landscape.
