<P>PROBLEM TO BE SOLVED: To reduce a processing load of a main control part while improving security strength by a simple method. <P>SOLUTION: A game machine 1 includes a main control part 110, an intermediate control part 180 and a peripheral part 300. The main control part 110 includes a main ROM 110b storing control commands and initialization information; a main CPU 110A outputting the control commands; and a transmitting part 500 generating an error inspection value of the control command and transmitting it to the intermediate control part 180. The main CPU 110a selects a specific addition method from a plurality of error inspection value addition methods which the transmitting part 500 has, as one piece of the initialization information in boot processing. The transmitting part 500 generates the error inspection value of the control command generated in the past, and adds it to the control command to be transmitted at present by the specific addition method. The intermediate control part 180 stores the error inspection value of the control command generated in the past, and inspects the validity of the received error inspection value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
