Fuzzy Based Key Agreement Scheme Using ECG Signals for Wireless Body Sensor Networks

Wireless Body Sensor Network (WBSN) is an emerging technology in the area of telemedicine. It helps doctors to remotely monitor the health condition of patients. The success of usage of WBSNs for health care monitoring relies mainly on the security provided to the medical information. In this paper, a fuzzy based key agreement scheme that uses ECG signal to protect the symmetric key to be exchanged is introduced. The effectiveness of the proposed scheme is evaluated using False Acceptance Rate (FAR) and our proposed system shows minimum FAR.
