Kaushik Dehingia, Nimisha Dutta · Journal of Cyber Security Technology · 2025
With the ever-increasing proliferation of Internet of Things (IoT) devices and advent in quantum computing, the need for quantum-secure cryptographic protocols is becoming more and more critical. This paper introduces a transformative approach to Quantum Key Distribution (QKD), integrating Quantum Neural Networks (QNNs) and adaptive entanglement protocols for securing, scaling, and rendering IoT communications resilient. The proposed architecture is scalable, hardware-efficient, and noise-resilient, enabling AI-assisted protocol optimization, dynamic qubit allocation, and QNN-based noise mitigation. Simulations with Qiskit and PennyLane produce a fidelity of 99.9% and achieve an average QBER of 0.015, representing a 32% reduction compared to the 0.022 QBER typically reported for Measurement-Device-Independent-QKD (MDI-QKD). The proposed QNN model classifies with an accuracy of 97.5%, significantly outperforming the VQNN’s 80.5%. A hierarchical quantum authentication scheme is also proposed to ensure multilayer security in heterogeneous IoT settings.
