<P>PROBLEM TO BE SOLVED: To improve security strength by a simple means and to reduce processing loads of a main control part. <P>SOLUTION: A game machine 1 includes a main control part 110 and a peripheral control part 300, and the main control part 110 includes an inspection value generation part 500 capable of generating an error inspection value by a plurality of generation systems, and a transmission part 550 for transmitting a command to the peripheral control part 300. The inspection value generation part 500 is provided between a main CPU 110a and the transmission part 550, and adds the error inspection value of the command generated in the past to the command to be transmitted at present. The inspection value generation part 500 changes a generation system on the basis of the error inspection value added to the transmitted command. Also, an input/output control system inside the inspection value generation part 500 is different from an input/output control system of the inspection value generation part 500 and the outside. The peripheral control part 300 generates the error inspection value for verification, inspects the propriety of the received command, and performs processing corresponding to an inspection result. <P>COPYRIGHT: (C)2013,JPO&INPIT |
