Security in IoMT-driven smart healthcare: A comprehensive review and open challenges

The Internet of Medical Things (IoMT) is a kind of communication environment, which deals with communication that occurs through the Internet of Things (IoT)-enabled smart medical (healthcare) devices. The potential security threats of IoMT affect the confidentiality, integrity, authenticity and availability of its data and the associated resources. In this review article, we explain various architectures of IoMT communication along with their applications. We highlight the security requirements of IoMT communication environment along with some potential security attacks and threats of IoMT. Furthermore, the network model and adversary model of IoMT communication are provided. A taxonomy of security protocols of IoMT communication environment is additionally added, which contains various security protocols, such as key management, user/device authentication, access control and intrusion detection protocols. Moreover, we provide a detailed comprehensive comparative analysis of several security protocols with respect to various parameters, like computation cost, communication cost, security features and functionality features, accuracy and F1-score. Additionally, we also provide some future research directions.
