Adapa, Venkata Rajesh Krishna (2025) Architecting quantum-resistant cybersecurity: A framework for transitioning to post-quantum cryptographic systems. International Journal of Science and Research Archive, 14 (1). pp. 737-746. ISSN 2582-8185

The emergence of quantum computing presents a significant threat to contemporary cryptographic systems, necessitating a fundamental transformation in cybersecurity architecture. This article presents a comprehensive framework for transitioning to post-quantum cryptographic solutions, examining both theoretical foundations and practical implementation strategies. Through systematic analysis, the article evaluates leading quantum-resistant algorithms, including lattice-based cryptography, hash-based schemes, and multivariate quadratic equations, assessing their viability for enterprise-scale deployment. The article addresses critical challenges in integrating these solutions into existing infrastructure while maintaining operational continuity and security assurance. The article proposes a structured approach to organizational preparation, incorporating risk assessment methodologies, resource allocation strategies, and adaptation frameworks for legacy systems. The findings demonstrate that successful transition to quantum-resistant cryptography requires a multi-faceted approach combining technical implementation with organizational readiness. This article contributes to the growing body of knowledge on post-quantum cybersecurity by providing actionable insights for organizations preparing for the quantum computing era, while highlighting areas requiring further investigation in the evolving landscape of cryptographic security.
