Highly secure and efficient architectural model for iot based health care systems

Internet of Things (IoT) can be perceived as enabling user-specific interoperable communication services by integration of sensing and actuation technologies with other leading technologies, such as telecommunication, networking, security and cloud computing etc. Application of the ubiquitous IoT technologies to augment healthcare systems inadvertently exposes the latter to unpredictable, disruptive cyber-attacks. Information and communication security is of utmost important as medical devices or sensors deployed to monitor and collect personal medical data are highly vulnerable to malicious hacker attacks. Moreover, compliance with industry standards and government regulations mandate security and privacy protection of health and medical information. In this paper we introduce a smart gateway which safeguards the entire system using modified Host Identity Protocol Diet EXchange (HIP-DEX) key exchange protocol and a new key exchange scheme based on Low Energy Adaptive Clustering Hierarchy (LEACH) routing protocol. Our proposed IoT based healthcare framework is designed to provide end-to-end privacy and protection from security breaches.
