Abstract:
1. An authentication apparatus comprising a body, and a partner side paired with the body, the apparatus comprising: a random pulse generator, arranged in the body or the partner side, or in both the body and the partner side, which generates random pulses; a means which outputs authentication data based on both a random pulse voltage and a random pulse interval of the random pulses generated by the random pulse generator; a means which stores authentication data, a communication means which transmits/receives authentication data; and a control means which controls the communication of authentication data and collates authentication data, wherein the random pulse generator detects a particles, a beta ray or a gamma ray released by the collapse of an atomic nucleus and generates the random pulses, wherein the random pulse interval of the random pulses is measured by counting the number of clock pulses, the counted number of clock pulses is used as a random number, and an interval of the clock pulses is shorter than the interval of the random pulses so as to enable the measurement of the random pulse interval by counting the number of clock pulses, and wherein said authentication data is outputted based on a combination of the random pulse voltage of the random pulses and a number of the clock pulses acquired by measuring the pulse interval of the random pulses.
