Power Attack Analysis Based on Biometric Cryptosystem

To assess the biometric cryptosystem performance in possible side-channel attacks,on the basis of analysis of the biometric cryptosystem structure and characteristics,a secure biometric cryptosystem based on the keystroke is designed by the combination of the user's keystroke biological characteristics and secret sharing scheme.Power consumption leakage of the safe biometric cryptosystem is measured with the Differential Power Attack(DPA).Simulation analysis shows the biometric cryptosystem can be extracted with bits of power leakages.
