PROBLEM TO BE SOLVED: To provide an information processor, for example, an entertainment device capable of assuring security of a driver, etc., of a device to be mounted. SOLUTION: A driver of an unknown device 611 is recorded in a memory card MC and other unknown device driver is recorded in the unknown device 611. Each driver is protected by encryption. Only the encrypted driver is made possible to read from a readable/writable medium such as the memory card MC. Since the unknown device driver is readable here, it is decrypted by a security module 90 and loaded in a RAM. Next, the unknown device driver 2 is read from the unknown device 611, decrypted by the security module 90 and loaded in the RAM. Thus, the memory card MC, unknown devices 611, 612 are simultaneously used in the entertainment device 1. |
