ABSTRACT:
A method of encrypting and decrypting a firmware used in electronic devices and an apparatus using the same. The firmware encryption method includes, receiving a predetermined special key data; generating an encryption key data from the predetermined special key data using a predetermined random number; generating an encryption data corresponding to firmware address information to be stored to a memory based on the encryption key data; and generating an encrypted firmware data by performing an XOR operation on the encryption data and firmware data to be stored in the firmware address.
