Quantum-Resistant Security in Digital Twin Healthcare Systems

Abstract

The development of digital twin (DT) systems for healthcare presents several challenges, particularly in ensuring data protection and communication security in real-time environments. The protection of patient information in the case of future quantum-powered attacks is one of the key issues, with traditional public-key cryptography tools being likely to be weakened in the context of the huge quantum computers. The objective of this research was to come up with a quantum-resistant security system to DT-based remote healthcare monitoring. With quantum-safe session key establishment with QKD or lattice-based postquantum interactions, along with symmetric authenticated encryption, secure far-edge, near-edge and cloud data transfer and processing was guaranteed. The results revealed a 40% reduction in latency, a 30% improvement in throughput and a 15% increase in system efficiency, demonstrating substantial enhancements in performance. The integration of quantum-resistant protocols provided robust protection without compromising system operation, achieving a 25.77% improvement in computational efficiency. The proposed framework significantly enhances the security, scalability and performance of remote healthcare systems, offering a future-proof solution against quantum computing threats.
