A Secure Remote User Authentication Protocol for Healthcare Monitoring Using Wireless Medical Sensor Networks
Abstract
The wireless medical sensor networks WMSN play a crucial role in healthcare monitoring remotely. In remote healthcare monitoring, the sensor nodes are deployed in patient's body for collecting physiological data and transmit these data over an insecure channel. The patient's health information is highly sensitive and important. Any malicious modification in physiological data will make wrong diagnoses and harm the patient health. Therefore, privacy, data security, and user authentication are extremely important for accessing patient's real-time heath information over an insecure channel. In this regard, this article proposes a secure and robust two-factor based remote user authentication protocol for healthcare monitoring. The authentication proof has done with the help of BAN logic, which ensures that the proposed scheme provides mutual authentication and session key agreement securely. The informal security verification proves that the developed protocol is secure from various security attacks. The simulation of the proposed scheme has been done using AVISPA tool, whose simulation results confirm that the proposed scheme is secure from active and passive attacks. Performance evaluation shows that the proposed protocol is efficient in terms of security features, computation cost, communication cost, and execution time.
