Abstract
Provided is a random number generating device capable of generating highly irregular random numbers with a simple configuration. The random number generating device includes: a receiving unit including a receiving mechanism configured to receive, in a contactless manner, energy transmitted from a transmitting unit, the receiving unit being configured to convert the energy received by the receiving mechanism into a reception voltage; a voltage controlled oscillator configured to output an oscillating output signal based on the reception voltage; and a pseudorandom number generator configured to generate pseudorandom numbers varying in accordance with an oscillation frequency of the output signal from the voltage controlled oscillator.
