Furkan Sayyed, Srivaramangai Ramanujam . Zero-Trust Quantum Authentication for Distributed Systems using Device-Independent Protocols and Qiskit Simulation. International Journal of Computer Applications. 187, 105 ( May 2026), 7-13. DOI=10.5120/ijcad7722d6000a6
Quantum computing disrupts conventional authentication techniques which rely on trusted measurement devices. The study presents a Zero-Trust Device-Independent Quantum Authentication Framework which authenticates users through Bell-state entanglement combined with CHSH inequality violations. The Qiskit simulation system tests its performance through four characters Alice Bob Charlie and Eve who simulate both typical and hostile operational scenarios. The secure situations demonstrate strong quantum correlations which reach a CHSH value of approximately 2.7 while the attack situations show major signal loss that makes reliable detection possible. The framework achieves over 93% accuracy in ideal conditions and demonstrates strong resistance to device-level and interception attacks. The research demonstrates that device-independent quantum authentication provides a secure and scalable authentication solution for future cloud and IoT and quantum network systems.
