In a modern healthcare environment, the adoption of mobile health care technology is promising to enhance the quality of patient monitoring of chronically ill as well as elderly and healthy individuals for quick intervention at any critical situation. The patient’s vital signs and physiological parameters can be monitored by the sensor nodes attached to the patient’s body sensor network which is then transmitted to the appropriate medical professional for further action through wireless communication media such as Bluetooth, WiFi, 3G/4G. At the same time, the security and privacy of the patient data are to be protected against the inherent threats and vulnerabilities in an unprotected environment. In this aspect, we have proposed an end to end mutual authentication scheme to ensure the security and privacy of the patient balancing security and performance. The proposed authentication scheme also makes use of PDA or a smartphone as a gateway node enabling continuous monitoring of the patient even in a nonclinical environment. In addition, the scheme includes the protocol steps for an emergency scenario, by which the quality of patient care is sustained in a critical situation. The security analysis shows that the proposed scheme is more efficient compared with other related schemes.
