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.

The integration of consumer-centric digital twin (CCDT) technology is set to transform healthcare systems, enabling blockchain-based solutions for enhanced medical services. By precisely simulating patients and medical processes, CCDT establish a link to the virtual healthcare environment, supporting improved diagnosis, real-time monitoring, and predictive analytics. Blockchain technology is critical in connecting the physical and virtual health care worlds, providing secure storage, efficient communication, reduced computational costs, and reliable hosting services. However, the security of patient data and its digital twin counterpart stored on the blockchain remains a potential vulnerability, as any alteration or unauthorized access to this information could pose significant risks. To address this challenge, we propose a blockchain-enabled quantum encryption protocol for CCDT healthcare networks to ensure secure communication. The proposed protocol leverages blockchain to authenticate patients without relying on third-party entities. At the same time, a secure quantum encryption mechanism ensures that CCDT do not need to authenticate repeatedly when interacting with multiple healthcare providers. A performance evaluation demonstrates the effectiveness of the proposed scheme compared to existing encryption methods. The results indicate that the suggested protocol is resilient against various security threats, showcasing its significant potential for enhancing communication security within CCDT healthcare networks.

Digital twins-enabled transportation cyber-physical systems are employed in the transportation sector to enhance environmental quality, mobility, and safety. They are digital representations of transportation networks, enable the simulation of these networks’ behavior under various conditions. They can be employed in various transportation sectors, including forecasting traffic congestion, facilitate the optimization of flow and safety, enhance the efficiency of public transportation, improve the efficiency of freight transportation by offering support in this process, facilitates the consideration of future multimodal infrastructure development requirements, furnish drivers with up-to-date information about weather alerts, road closures, and traffic situations in real time, assess numerous aspects like, impacts of various mobility operators, transport users, and environmental conditions. However, the real-time data synchronization in digital twins-enabled transportation cyber-physical systems is accomplished using an open communication channel. Regrettably, the utilization of virtual-reality synthesizing security threats in the network necessitates the implementation of stringent privacy and security procedures, including authentication, encryption, and signature approaches. This study proposes a quantum-key-distribution (QKD)-based authentication protocol for secure communication of digital twins-enabled transportation cyber-physical systems. The integrated quantum in the system ensures the compactness and verifiability of data. The protocol’s security is examined using the Scyhter tool and is verified to be secure by informal security analysis. The proposed scheme achieves its efficiency over current solutions. Moreover, the latest technology and techniques are used to examine the operational capabilities and security features.
