Abstract: Identification information of a program read from outside, such as firmware, is acquired, and usability of a piece of key data in a range corresponding to the identification information is set, among a plurality of pieces of key data to be used for the program. As another example, based on new key data generated based on key data stored in advance in a memory and identification information, firmware corresponding to the identification information is decrypted.
