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.
