Cloud based mutual authentication scheme in multi gateway healthcare environment

Wireless Body Sensor Network (WBSN) has gained attention due to its potential in improving the quality of healthcare services especially during the recent pandemic across the globe. Using WBSNs, vital signs of the patient can be gathered from the different sensor nodes equipped on the patient’s body and can be accessed by the healthcare professional using a mobile device ensuring confidentiality and anonymity. The physiological data collected by sensor devices may be stored in a cloud based environment and can be accessed by a doctor for a suitable treatment. In a modern healthcare environment, the globally connected IoT, sensors, gateways and cloud based infrastructure brings new opportunities for assisting medical professional to provide on demand and real time patient monitoring services with higher accuracy and better efficiency. the gateway and the cloud server with mobility management. The proposed authentication scheme is augmented with a secure roaming protocol that will allow the patients’ body sensors to use the roaming services delivering the health data to the cloud server through the foreign gateway. The security of the designed protocol is analysed against various attacks using BAN logic and AVISPA tool.
