PROBLEM TO BE SOLVED: To provide a security chip having communication function, which dispenses with an inspection for checking illegal action and alteration of a chip to be packaged on a control substrate after the authentication of the chip. SOLUTION: This security chip is composed of a clock generating circuit 10, central processing unit 11 for game machine control, incorporated RAM 13, user program storage means 14, security check circuit 16, reset circuit 12, ID number storage circuit 15, external communication control circuit 18 and external I/F circuit 20. The security chip has a function for transmitting the rightness/wrongfulness or identification number of the chip corresponding to the instruction by an external managing device 22. Otherwise, the information of great success or small success from a game machine information I/F circuit 19 is stored, the information is outputted corresponding to an instruction and the information of balls to be supplied or collected by a detecting means 21 or the like is outputted. The external communication control circuit has an enciphering circuit and a deciphering circuit, communication is performed while being enciphered and security is added. |
