Efficient anonymous authentication with key agreement protocol for wireless medical sensor networks
The use of wireless medical sensor networks (WMSN) in healthcare has led to a significant progress in this area. WMSN can sense patients' vital signs and transmit sensed signals to health monitoring devices. Health professionals can monitor the status of patients. Confidentiality and patient privacy are the main concern for the WMSN in health care. Recently, He et al. proposed an authentication protocol for the healthcare applications using WMSN. In this paper, we show that He et al.'s scheme is insecure against various attacks. We also present an improved scheme. In the security analysis, we demonstrate that our scheme is secured against various attacks. We use the BAN logic to prove the correctness of the proposed scheme. As a result, the proposed protocol is practical for healthcare applications.
