Secure-iGLU: A Secure Device for Noninvasive Glucose Measurement and Automatic Insulin Delivery in IoMT Framework

The growth of healthcare technologies has made a great impact on human life for the last few years. Various innovations in implantable and wearable medical devices improve the quality of life. Internet-of-Medical-Things (IoMT) based smart healthcare with continuous sensing, connectivity, and automatic medication is the latest trend. With the growth of technologies and connectivity, the security of these devices is a growing concern. The security of medical devices is important as the security compromise may lead to critical situations. This paper explores the security aspect of the IoMT system with a non-invasive glucose monitoring device integrated with an insulin delivery system (called iGLU) as a specific example. We call this secure system as Secure-iGLU. The paper presents a Hardware-Assisted Security (HAS) paradigm using Physical Unclonable Function (PUF) to design Secure-iGLU. PUF is a useful primitive to generate fingerprint of the hardware, and it has a great potential to mitigate the security problem of iGLU. The simulation results confirm the security of our Secure-iGLU using PUF in IoMT with safe insulin delivery system.
