A Framework for Post Quantum Migration in IoT-Based Healthcare Systems
It addresses the need for quantum-safe security in IoT-based healthcare systems, but the framework is conceptual without concrete implementation or evaluation.
This paper examines the quantum threat to IoT-based healthcare systems and proposes a comprehensive migration framework using a phased hybrid approach with crypto-agility to transition to quantum-safe cryptography, tailored to resource-constrained devices and interoperability challenges.
Smart healthcare industry is increasingly relying on Internet of Things (IoT) devices to improve patient care and operational efficiency. However, the cryptographic algorithms that enable fundamental security and are widely used in these cyber systems are vulnerable to attacks by emerging quantum computers - known as Quantum Threat. This paper examines the quantum threat to healthcare IoT across the four layers of the IoT architecture: physical, network, perception, and application. It proposes a comprehensive migration framework integrating a phased hybrid approach with crypto-agility to transition healthcare IoT systems to quantum-safe cryptography. This framework prioritises resource-constrained devices, emphasises interoperability, and considers the challenges of vendor readiness and infrastructure upgrades. This paper contributes a detailed, phased migration plan specifically tailored to the unique security needs and resource limitations of IoT-based healthcare systems.
