Secure health monitoring using medical wireless sensor networks

In this paper, we are addressing security requirements of health monitoring using medical sensor networks and proposed a secure framework called “SHM ” using wireless sensor networks. SHM provides security services such as confidentiality, authenticity and integrity to patient data at low-cost. To provide confidentiality we have used PingPong-128 stream cipher. Authenticity and data integrity is achieved by PingPong-MAC (message authentication code). We have designed a real-time prototype with ECG and tri-axial accelerometer sensors on Telos-mote for evaluating the proposed secure framework and our results confirm their feasibility.
