description Disclosed is an authentication device including a plurality of physical unclonable function (PUF) chips to reinforce security performance. According to the present invention, the authentication device comprises a plurality of PUF chips outputting different response data to the same challenge data. The authentication device selects at least one PUF chip from among the plurality of PUF chips according to an authentication information generation rule shared with a server and generates PUF authentication information by using response data at the time when the challenge data is input to the selected PUF chip. The PUF authentication information can used to extract an authentication result through comparison with server authentication information generated by the server according to the same authentication information generation rule as an authentication information generation rule used to generate the PUF authentication information. 복수의 PUF 칩들을 포함하는 인증 장치가 개시된다. 인증 장치는 동일한 첼린지(Challenge) 데이터에 대해 서로 다른 응답(Response) 데이터를 출력하는 복수의 PUF(Physical Unclonable Function) 칩들을 포함하고, 상기 인증 장치는 서버와 공유하는 인증 정보 생성 규칙에 따라 상기 복수의 PUF 칩들 중 적어도 하나 이상 PUF 칩을 선택하고, 상기 선택된 PUF 칩에 첼린지 데이터를 입력하였을 때의 응답 데이터를 이용하여 PUF 인증 정보를 생성하며, 상기 PUF 인증 정보는 상기 PUF 인증 정보를 생성하는데 사용한 인증 정보 생성 규칙과 동일한 인증 정보 생성 규칙에 따라 서버에 의해 생성된 서버 인증 정보와의 비교를 통해 인증 결과를 도출하는데 사용될 수 있다.
