PROBLEM TO BE SOLVED: To provide a boot program, information processor, information processing system, information processing method, semiconductor device, and program capable of improving the secrecy of a program such as firmware read from the outside.SOLUTION: Identification information of a program such as firmware read from the outside is acquired, and, of a plurality of key data used for the program, the use propriety of the key data in a range corresponding to the identification information is set. As another example, the firmware corresponding to the identification information is decoded on the basis of new key data generated on the basis of the key data and identification information previously stored in a memory.SELECTED DRAWING: Figure 3 |
