A Mutual Authentication Framework for Wireless Medical Sensor Networks

AbstractWireless medical sensor networks (WMSN) comprise of distributed sensors, which can sense human physiological signs and monitor the health condition of the patient. It is observed that providing privacy to the patient ’s data is an important issue and can be challenging. The information passing is done via the public channel in WMSN. Thus, the patient, sensitive information can be obtained by eavesdropping or by unauthorized use of handheld devices which the health professionals use in monitoring the patient. T herefore, there is an essential need of restricting the unauthorized access to the patient’s medical information. Hence, the efficient authentication scheme for the healthcare applications is needed to preserve the privacy of the patients’ vital signs. To ensure secure and authorized communicati on in WMSN, we design a symmetric key based authentication protocol for WMSN environment. The proposed protocol uses only computationally efficient operations to achieve lightweight attribute. We analyze the security of the proposed protocol. We use a formal security proof algorithm to show the sche me security against known attacks. We also use the Automated Validation of Internet Security Protocols and Applications (AVISPA) simulator to show protocol secure against man-in-the-middle attack and replay attack. Additionally, we adopt an informal analysis to discuss the key attributes of the prop osed scheme. From the formal proof of security, we can see that an atta...
