Quantum-Edge IoT: A Framework for Quantum-Accelerated Optimization and Post-Quantum Security in Internet of Things Systems

Complex infrastructures integrate Internet of Things (IoT) and Edge Computing (EC) to provide heterogeneous users with in-brim services resembling caching. These assimilated environments are security demanding because of the legacy and future computer/ system vulnerabilities. This article presents a Quantum-Innovated Authentication Framework (QIAF) to improve the security of IoT-EC through post-quantum cryptography based on lattice-based designs. The proposed framework combines sophisticated lattice vulnerability assumptions and module learning in order to execute protected key exchange through the di-lithium scheme. This framework can be used to obtain sustainable resistance against legacy and quantum adversaries with security by combining structured lattice trapdoors and adaptive scheme parameter tuning. This framework helps in the preservation of data integrity and confidentiality in quantum-threatened scalable environments by incorporating the authentication within the current IoT-EC infrastructures, providing secure and future-proof security guarantees. For the varying users, the proposed framework is found to reduce the time taken for authentication by 11.36% and verification time by 11.71%.
