Review on security of Wireless Body Area Sensor Network

The development of miniaturized implantable bio-sensors is an emergent technology resulting from various fields of human endeavour such as engineering, computer science, telecommunication, instrumentation, nano-technology etc. Wireless Body Area Sensor Network (WBASN) is a network of implanted biosensors on/inside the human body for remote health monitoring. Considering the need for a reliable health care information system, security of WBASN is key to effective remote health monitoring of users and the development of proper mobile-health (e-health) care delivery system. In this paper, we present the concept of WBASN, the applications, security challenges and a review on security as it pertains to WBASN.
