Quantum-Resistant Cryptographic Protocols: Implementation Challenges in Critical Infrastructure Systems
Subject area: Science,Engineering and Technology · Area of research: Post-quantum Cryptography
Abstract
The advent of quantum computing poses an existential threat to contemporary cryptographic systems that secure critical infrastructure. This article examines the technical, operational, and organizational challenges associated with implementing quantum-resistant cryptographic protocols in critical infrastructure environments. Performance constraints, resource limitations, and backward compatibility issues are analyzed across energy, transportation, healthcare, and financial sectors. Through comparative analysis and empirical evaluation, we present sector-specific implementation barriers and propose a comprehensive transition framework that balances heightened security requirements with operational constraints. My findings indicate that while immediate wholesale migration presents significant challenges, a strategically phased hybrid approach can achieve quantum resistance while maintaining operational integrity. This research contributes to the growing body of knowledge addressing the urgent need for quantum-safe infrastructure protection strategies.
