Abstract
It is made possible to provide a random number generation device which generates a physical random number with as little power dissipation as possible. A random number generation device includes: a ring oscillator having at least one set, each set comprising a current noise source and a Schmitt inverter configured to receive an output of the current noise source; and a conversion circuit configured to convert output frequency fluctuation of the ring oscillator to a random number and output the random number.
