Securing the Internet of Medical Things using PUF-based SSI Authentication

The proliferation of Internet of Things (IoT) technologies has revolutionized the medical domain, offering enhanced reliability and efficiency. However, the inherent vulnerability of these devices, often equipped with inadequate authentication mechanisms, poses significant threats to user privacy. To address these challenges, user-centric authentication leveraging asymmetric encryption has emerged as a valuable security measure across various domains. In this manuscript, we introduce a novel approach to authentication within the domain of the Internet of Medical Things (IoMT), capitalizing on the integration of Self-Sovereign Identity (SSI) and SRAM-based Physical Unclonable Function (PUF). Our approach stands out for its efficacy in resource-constrained environments, ensuring robust security without compromising operational efficiency. We present a concrete implementation under the SSI paradigm, showcasing a convenient time complexity, indicating its efficiency and suitability for practical use.
