With the fast development of wireless communication technologies and semiconductor technologies, the wireless sensor network (WSN) has been widely used in many applications. As an application of the WSN, the wireless medical sensor network (WMSN) could improve health-care quality and has become important in the modern medical system. In the WMSN, physiological data are collected by sensors deployed in the patient’s body and sent to health professionals’ mobile devices through wireless communication. Then health professionals could get the status of the patient anywhere and anytime. The data collected by sensors are very sensitive and important. The leakage of them could compromise the patient’s privacy and their malicious modification could harm the patient’s health. Therefore, both security and privacy are two important issues in WMSNs. Recently, Kumar et al. proposed an efficient …
