SCI(E) 논문입니다.
- Protection of private key is the most critical part in public key infrastructure (PKI) system since it depends on the confidentiality of private key. Thread of password detection has been known as the vulnerability in this PKI system. Recently, studies have been conducted on BioPKI system that uses the biometric information of users in order to replace the password type of private key Protection in PKI system. However, BioPKI system also has vulnerability in that biometric information used for Protection of private key cannot be reused once it is stolen or lost. So, we propose the method to protect the private key using FIDSEQi which binds sequence to biometric information. the proposed method enhances reusability of biometric information and presents higher attack complexity than the method of authentication by cross matching single biometric information.W640
