DOOR LOCK SECURITY DEVICE BY USING REAL-TIME PASSWORD GENERATOR

摘要

PURPOSE: A door lock security device by using a real-time password generator is provided to improve the security by preventing the valuables from rubbery as well as to improve the convenience of the user by easily and removably connecting the authentication input block of the RTP door lock security device. CONSTITUTION: A door lock security device by using a real-time password generator(RTP) includes an authentication input block(21), an authentication interface block(41), an authentication driver block(42), an authentication memory block(43), a main authentication block(44) and a control block(31). In the door lock security device, the authentication input block(21) inputs the data by connecting to the key lock device. The authentication interface block(41) implements the multi-stages user authentication process by the RTP. The authentication driver block(42) stores the RTP encryption algorithm and implementation code used during the user authentication. The authentication memory block(43) implements the encryption operation in response to the RTP module. The main authentication block(44) implements the multi-stage user authentication work by processing the encryption operation in response to the RTP module. And, the control block(31) drives the switching means if the user authentication is finally achieved.
