METHOD OF GENERATING FIRMWARE UPDATE FILE, METHOD AND APPARATUS FOR UPDATING FIRMWARE BY USING THE FIRMWARE UPDATE FILE

摘要

Provided are a method of generating a firmware update file which restrictively allows a firmware update for a corresponding hardware model, and a method and apparatus for updating firmware using the firmware update file. By generating a data body including program codes of firmware to be updated, generating a data header including model codes of a hardware device to which the data body is applied, and generating the firmware update file by combining the data body and the data header, the firmware update may be restricted for a corresponding model of a hardware device by using the firmware update file so that firmware of other models of hardware devices may not be updated, an integrity check may be performed using a digital signature when the firmware is updated.
