Zusammenfassung:The present invention relates to a nuclear digital controller authentication method based on one time password (OTP) for authenticating connection between an engineering work station (EWS) and a nuclear digital controller. According to the present invention, the nuclear digital controller authentication method based on OTP may comprise the steps of: requesting authentication of a password when a second application program is executed in response to the execution of a first application program installed in the EWS; if the password is authenticated, requesting first OTP authentication; monitoring whether connection login is attempted to connect with the nuclear digital controller after the first OTP authentication is successful; when the connection login is attempted, requesting second OTP authentication; and if the second OTP authentication is successful, connecting the first application program and the nuclear digital controller. 본 발명에 따른 OTP 기반의 원자력 디지털 제어기 인증 방법은, 엔지니어링 작업 장치(EWS : Engineering Work Station)와 원자력 디지털 제어기 간의 연결을 인증하는 방법으로서, 상기 EWS에 탑재된 제 1 응용 프로그램의 실행에 응답하여 제 2 응용 프로그램이 실행되면 패스워드의 인증을 요청하는 단계와, 상기 패스워드가 인증되면, 1차 OTP 인증을 요청하는 단계와, 상기 1차 OTP 인증이 성공한 후 상기 원자력 디지털 제어기와 연결하기 연결 로그인의 시도 여부를 모니터링하는 단계와, 상기 연결 로그인이 시도되면, 2차 OTP 인증을 요청하는 단계와, 상기 2차 OTP 인증이 성공하면, 상기 제 1 응용 프로그램과 상기 원자력 디지털 제어기를 연결시키는 단계를 포함할 수 있다.
