Advances in microelectronics, material science and wireless technology have led to the development of sensors that can be used for accurate monitoring of inaccessible environments. Health monitoring, telemedicine, military and environmental monitoring are some of the applications where sensors can be used. The sensors implanted inside the human body to monitor parts of the body are called biosensors. These biosensors form a network and collectively monitor the health condition of their carrier or host. Health monitoring involves collection of data about vital body parameters from different parts of the body and making decisions based on it. This information is of personal nature and is required to be secured. Insecurity may also lead to dangerous consequences. Due to the extreme constraints of energy, memory and computation securing the communication among the biosensors is not a trivial problem. Key distribution is central to any security mechanism. In this paper we propose an approach wherein, biometrics derived from the body are used for securing the keying material. This method obviates the need for expensive computation and avoids unnecessary communication making our approach novel compared to existing approaches.
