Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, a secure biometric authentication protocol is proposed which can authenticate users using encrypted biometric information. The system model is a three party model which consists of a user, an authentication server, and a decryption center. Previously, a similar protocol was known which uses conventional homomorphic encryption schemes such as Paillier encryption scheme.In that protocol, however, user's plaintext biometric data is required in the authentication phase, which leads the number of procedures between a user and an authentication server to $O(N)$ in the case of $1:N$ authentication. This paper proposes a protocol which uses 2-DNF homomorphic encryption schemes. This protocol requires no plaintext biometric data for the authentication phase,which reduces the number of procedures to $O(1)$ for $1:N$ authentication. A concrete protocol is demonstrated which employs Okamoto-Takashima homomorphic encryption scheme that provides 2-DNF homomorphism. The protocol is proved to be secure in the semi-honest model.
