Secure Communication in BAN using Modified Fuzzy Vault Scheme R.Rekha

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 private information collected by the sensors. Security depends on key agreement scheme used. This paper aims at developing a fuzzy based key agreement scheme that uses ECG signal to protect the symmetric key to be exchanged. Here the correlation attack is overcome by using two different polynomial of different order due to which the integrity property of system is preserved. The effectiveness of the proposed scheme is to improve the performance of the system by overcoming correlation and collusion attacks. It also aims at minimizing False Acceptance Rate (FAR) and False Rejection Rate (FRR)
