LA-IMDCN: A Lightweight Authentication Scheme With Smart Contract in Implantable Medical Device Communication Networks

Implantable medical devices (IMDs) in medical sciences have provided a quantum leap in network transformation. The communication network with IMDs typically has a wireless radio frequency (RF) telemetry or wired connection. IMDs, being devices, have more computing, communication capabilities and decision-making. Furthermore, these devices are being used to improve patients’ quality of life by medicating various chronic diseases. The captured data is stored in a medical server through a controller node. Our work focuses on wireless communication, so sensitive patient data over a public channel might be tampered with or eavesdropped by unauthorised access. Furthermore, the leakage of health data and malfunctioning of IMDs are vital in constructing cryptographic protocols, particularly in the design of remote user authentication. In this paper, we proposed a novel secure remote user authentication scheme using a lightweight consortium blockchain for the communication network with IMDs.
