Abstract
An apparatus and method that stabilizes an output sequence of a real random number generator by adjusting the input voltage of the random number generator or the comparative voltage of a comparator. The apparatus for stabilizing an output sequence of a real random number generator includes a verification unit for performing a monobit test on random number values sampled by and output from a comparison unit, and calculating an impact value. An adjustment unit adjusts a voltage of any one of a random number generation unit and the comparison unit using resulting values of the monobit test and the impact value output from the verification unit.
