Quantum-Safe Network Access Control Framework: A Post-Quantum Cryptographic Approach to Future-Proof Authentication and Authorization Systems
Abstract
Quantum computing developments create significant threats to Network Access Control systems built upon classical cryptographic methods, which are susceptible to quantum-based computational attacks. This framework tackles the essential shift from conventional encryption techniques to quantum-resistant solutions while preserving uninterrupted operations across enterprise networks. The implementation combines post-quantum cryptographic standards such as CRYSTALS-Kyber, CRYSTALS-Dilithium, and NTRU-based techniques within current NAC deployments using hybrid system architectures. The solution features advanced protocol negotiation mechanisms, computational enhancement techniques, and structured transformation processes that facilitate smooth migration without compromising essential authentication functions. Implementation considerations encompass algorithm agility, certificate management modifications, and comprehensive testing procedures that ensure security effectiveness against both classical and quantum threats. The solution addresses computational overhead challenges through parallel processing, hardware acceleration, and intelligent caching mechanisms while providing rollback capabilities and contingency planning for risk mitigation during deployment phases.
