If the analysis result of the fourth step is tagged, the first NFC module 122 ) As an NFC tag for requesting a door lock password and waiting for operation as an NFC reader function for the second NFC module 210 of the mobile smart device 200; And
When the first Bluetooth module 126 is automatically activated in the fifth step because the adonyno board 120 can not be tagged as a result of the analysis in the fourth step, the first Bluetooth module 126 is controlled, Transmits an activation request for the second Bluetooth module 270 of the mobile smart device 200 to the second Bluetooth module 270 of the mobile smart device 200 via the first Bluetooth module 126 Receives the door lock password from the second Bluetooth module 270 of the mobile smart device 200 through the first Bluetooth module 126 and transmits the received door lock password to the door lock password stored in the storage module 125 A door lock unlocking operation, and a door lock unlocking operation. / RTI >
In the sixth step,
When the first NFC module 122 operates as an NFC tag for requesting a door lock password in the fifth step, the first NFC module 122 can perform tagging of the first NFC module 122, (NFC) for requesting a door lock password, and waiting for the NFC module to operate as an NFC reader for the second NFC module 210 of the mobile smart device 200; When the mobile smart device 200 receives the door lock password request from the adonyno board 120 through the second NFC module 210, the door lock password information is recognized through the input / output unit 220 or stored in the storage unit 240 6-2 < / RTI > step of extracting door lock password information previously stored in the door lock password information storing step; The mobile smart device 200 operates the second NFC module 210 as an NFC tag for door lock password transmission so as to wait for the first NFC module 122 of the adonaboard 120 to operate as an NFC reader 6-3; The adorno board 120 receives the door lock password from the second NFC module 210 of the mobile smart device 200 as a result of the NFC tagging for the second NFC module 210 through the first NFC module 122 Step 6-4; And if the door-lock board 120 receives the door-lock password, the controller locks the door-lock lock when the door-lock password is identical to the door-lock password stored in the storage module 125; Further comprising:
In the second step, after receiving the unique identification number of the mobile smart device 200 in addition to the identification name, the adouno board 120 binarizes the identification name and the unique identification number to perform a series of plain text block information conversion And performing a secondary encryption using a preset encryption key to reinforce the complement of the NFC-based door lock device.
The method according to claim 1, wherein, in the second step,
After the adonyno board 120 performs one-stage encryption to generate an intermediate constant by applying block encryption to the plaintext block information by the encryption key, the generated intermediate constant and each individual information (identification name and unique identification number) The encryption key is transmitted from the mobile smart device 200 to the second smart card 200 in order to unlock the door lock at a later time by performing an exclusive logical OR operation on each of the plurality of plaintext blocks, When the unique identification number of the mobile smart device 200 is received in addition to the identification name, it is decrypted in a reverse order of encryption and used to perform access to information. The door-based door lock device having the NFC module is called an NFC- Way. delete delete delete
