Designing a Secure and Lightweight Ecosystem for Internet of Medical Things (IoMT) in Healthcare

Abstract

The surge in internet of things (IoT) devices, especially in healthcare's internet of medical things (IoMT), demands a nuanced balance between security and resource constraints. This chapter outlines a design framework for a lightweight and secure IoMT ecosystem, focusing on lightweight cryptography, secure routing protocols, and critical trade-offs. Careful selection of cryptographic algorithms like AES-CCM and Keccak addresses medical device limitations. Proposing routing protocol for low power and lossy networks (RPL) for resource-constrained contexts, the chapter advocates secure neighbor discovery algorithms and cryptographic protocols to fortify the network, ensuring communication legitimacy. Building a secure IoMT involves navigating trade-offs, balancing latency vs security, scalability vs security, and maintaining current security protocols while minimizing damage. Reliable authentication and access control are crucial, verifying identities and safeguarding medical information security and privacy.
