| Abstract(in English) | We propose the scheme that stores protected secret key which is made by combination of biometrics and secret key in the smartcard in PKI. In our proposal, the user encrypts the secret key using biometrics information extracted from owner of that secret key and stores it as protected secret key in smartcard which has fingerprint reading function. The user can restore the secret key form protected secret key by presenting his fingerprint to smartcard that has protected secret key and helper data. In our scheme, the template is not need for authentication. So, the problem of the leaks of the template which arise in traditional biometric authentication won ' t arise in our scheme. |
