SECURITY ARCHITECTURE FOR AT-HOME MEDICAL CARE USING BODY SENSOR NETWORK

Body Sensor Networks have considerably facilitated the continuous measurement of physiological parameters of human body. The sensors used to measure the body parameters, have several limitations in terms of power, computation capability, memory and communication capability. In this paper a novel architecture has been proposed to ensure continuous, unobtrusive and remote patient monitoring, taking into account the inherent hardware constraints of the sensors. The proposed architecture would enable senior citizens, patients with chronic ailments and patients requiring post-operative care to be remotely monitored in the comfort of their homes. Security threats and challenges inherent to wireless communication of sensor data have been discussed and a security mechanism to ensure data confidentiality, integrity and authentication has been proposed.
