ABSTRACT:
A mutual authentication system authenticates a first electronic device and a second electronic device by transmitting authentication data between the first and second electronic devices. In this system, the second electronic device transmits a first authentication data to the first electronic device. In the first electronic device, the legitimacy of the second electronic device is determined based on the first authentication data transmitted from the second electronic device. The first electronic device also transmits a second authentication data, which is used for determining the legitimacy of the first electronic device, to the second electronic device. When the second electronic device is not determined to be legitimate by the first electronic device, the first electronic device does not transmit the second authentication data to the second electronic device.
