Abstract:
A random number generating device includes an uncertain circuit which outputs uncertain data, and a cipher processing device. The cipher processing device encrypts input data using a cipher function of the cipher processing device, and generates a random number including higher uniformity than data outputted from said uncertain circuit using the cipher function of the cipher processing device and the data outputted from the uncertain circuit.
