Safeguarding the Internet of Health Things: advancements, challenges, and trust-based solution

The applications of IoHT have adapted a lot of contemplation as a result of recent IoT (Internet of Things) advancements. Irrespective of several fields in IoHT such as remote medical professional assistance, history of health-charting, integrated care management, decreased cost, disease management, disability management, home care management, individual healthcare assistance, health tracking, drug availability management, healthcare tracking management, and telesurgery. The evolvement in the field of the IoHT network has shown a drastic advancement in the standard of living. Despite the numerous fields of application in the IoHT network, the balance of security and privacy is one of the most pressing problems as far as life-critical solutions are concerned. There are several solutions to maintain security in the IoHT network. The most recent security enhancement schemes in the IoHT have been addressed in this paper. Furthermore, the latest possible challenges in the IoHT network are discussed. Moreover, an extensive survey on future research directions in the field of IoHT network security is illustrated. Additionally, we have proposed a security architecture based on trust assessment for IoHT systems to ameliorate the security of the network. The trust assessment is based on the artificial intelligence mechanism such that the security of the IoHT network is enhanced adaptively. This paper presents a novel IoHT security framework that integrates trust evaluation to dynamically address security challenges. It offers practical solutions for applications like telesurgery by adjusting measures based on real-time trust assessments, setting a new standard in IoHT security and guiding future research.
