Lightweight Authentication Schemes for Internet of Medical Things

Internet of Medical Things (IoMT) is a promising paradigm that has been raised thanks to the development of the Internet of Things(IoT) and cloud computing to support Wireless Body Area Networks (WBANs). Although it provides remote and real-time health monitoring, IoMT exposes smart devices to new vulnerabilities and expands cyber attacks to cyber-physical attacks. Hence, authentication is a primordial security measure in any E-healthcare system. IoMT communication relies on low-power smart wearable devices to transmit Electronic Medical Records (EMRs); hence, it is essential to design lightweight authentication schemes that do not require complex cryptographic methods. In this work, we evaluate a set of lightweight authentication schemes based on the one-way hash function and the Physically Unclonable Function (PUF) in terms of security and resistance to various attacks and in terms of performance.
