<P>PROBLEM TO BE SOLVED: To provide a game machine capable of increasing the security strength. <P>SOLUTION: A main control portion of the game machine includes: an output means for outputting a control command; a first generating means capable of generating an individual test value by using a prescribed control command output in the past and an accumulated test value by using control commands output in the past; a first determination means for determining a test value to be added to a control command to be transmitted next based on the test value transmitted at the time; and a transmission means for adding a false test value according to the determination by the first determination means to a control command and transmitting the control command to an intermediate control portion. The intermediate control portion includes: a second generating means capable of generating an individual test value and an accumulated test value; a second determination means for determining a test value to be used in the next false test based on the test value used in the false test at the time; and a test means for testing the validity of the control command transmitted at the time by using the false test value transmitted at the time and the false test value according to the determination by the second determination means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
