ABSTRACT:
The present invention provides a semiconductor device such as an IC capable of generating completely random signals and generating an authentication signal, random number, and probability by integrally setting a random pulse generation source for spontaneously generating at the inside, and also provides a method/program for generating a random number and/or probability, comprising the steps of setting a random pulse generation source (hereafter referred to as RPG) for spontaneously generating random pulses, measuring the time interval between the random pulses generated from the RPG or measuring a voltage value of the random pulse, and converting it into a digital value, and generating an exponential distribution random number and/or uniform random number having a predetermined bit length and/or a probability from random pulses as converted to digital values.
