In wireless body sensor networks (WBSNs), sensors continuously monitor human physiological activities using medical sensors, for example; blood pressure, body temperature and electrocardiography (ECG). A WBSN can be used to develop a patient monitoring system. The traditional body sensor networks (BSNs) have limited hardware resources in terms of computational capabilities, data processing speed, memory and battery life. Also these BSNs are generally not suitable for the implementation of security mechanisms, reason is that, implementation of security mechanisms require relatively more hardware resources because of the complexity of their algorithms. To get rid of these limitations a Field Programmable Gate Array (FPGA) device is suitable because of its flexible architecture and high performance features. In this paper an FPGA based experimental framework is investigated to implement real time body temperature monitoring with reliable data transmission, using data integrity verification. This data integrity check is very important for patient monitoring systems as unreliable data could lead the healthcare professionals to make an incorrect diagnosis concerning patients health. The data integrity verification is achieved using newly selected cryptographic hash function called, SHA-3 (Secure Hash Algorithm-3). To the best of authors knowledge, all previously published FPGA based WBSNs implementations did not implemented any security mechanisms to secure physiological data, so this work is the first contribution regarding it.
