| titleOfInvention | Method for Authenticating between Printer and Cartridge by using One Time Password |
| abstract | The present invention relates to a method of authenticating between a cartridge and a printer using an OTFT, and in a printer and a printer equipped with the cartridge, a method of authenticating a cartridge by communicating with a module of the cartridge, When the effective seed value (C_SEED) is not stored in the designated seed storage area of the module installed in the cartridge to be mounted, the printer receives the serial number from the module of the cartridge, and when the serial number is received, The seed value G_SEED is stored in the designated seed storage area of the module of the cartridge when the cartridge is loaded into the printer, or the seed value C_SEED is stored in the designated seed storage area of the module of the cartridge When the seed value C_SEED is stored in the car, Side time held in the module from the module of the ridge, and the time synchronized with the module-side time held by the module based on the printer-side time that the printer is confirmed through the timer on the printer side Checks the stored value for calculation, confirms the serial number received from the module, matches the seed value (G_SEED) provided to the module of the cartridge to confirm the seed value (P_SEED) to be kept on the printer side, (C_SEED) stored in the seed storage area designated by the module of the cartridge and the seed value (C_SEED) stored in the module side of the authentication time when the mounted cartridge is authenticated, Receives the OTP generated using the time value (C_TIME) and the serial number of the module, and the printer Comparing the serial number with the stored serial number to determine whether the received OTP is an OTP generated through a module of the cartridge, and if the received OTP is confirmed to be generated through a module of the cartridge, (P_TIME ') using the stored storage value, and the printer confirms the stored seed value (P_SEED) by using the serial number, The OTP is generated through the identified seed value P_SEED and the time value P_TIME 'and compared with the received OTP to authenticate. When the OTP is authenticated, the printer controls the printing operation using the cartridge to be performed . |
