SecHealth: An Efficient Fog Based Sender Initiated Secure Data Transmission of Healthcare Sensors for e-Medical System

Security on sensitive data of the patients is essential in e-medical system where, sensors and the servers use the insecure channels like ZigBee and Internet to exchange their information. An adversary may hamper the communications by mounting various attacks as well as he/she may try to get the sensitive data. Therefore, security system is needed so that it can protect the security attacks. This paper provides a new security protocol, referred as SecHealth when the healthcare sensors transmit their data to a local server known as fog server. In this case, after verifying each other (i.e., sensor and fog server), then only the sensors are able to transmit their data to the local fog server. However, security analysis of the proposed protocol states that it can overcome all the possible known attacks.
