    • The present invention relates to a random-number generating apparatus and method for generating physical random numbers in accordance with noises randomly generated by a noise generating element, and allows for generating true random numbers at a high speed and uniformizing the generation frequency of each random number value, even in a simplified circuit configuration. The random-number generating apparatus is operable to amplify a waveform based on thermal noises generated in a thermal-noise generating element, and generate a random pulse at the time when the amplified output signal exceeds a given threshold from the state of being less than the threshold. The random-number generating apparatus is also provided with a reference-pulse generator for generating a reference pulse having a constant period, and a timer for measuring a time interval between the reference pulse and the random pulse. The measured value in the timer is output as a random number value.
