RANDOM NUMBER GENERATING DEVICE

摘要

Provided is a random number generating device capable of generating highly-random random numbers using a simple configuration. This random number generating device is provided with: a receiver unit (100) which has a receiver mechanism (101) for receiving energy transmitted from a transmitter unit (20) without making contact therewith and transforms the energy received by the receiver mechanism (101) into a reception voltage (VIN); a voltage controlled oscillator (110) for outputting, on the basis of the reception voltage (VIN), an oscillating output signal (CKIN); and a pseudo random number generator (120) for generating pseudo random numbers that vary according to the oscillation frequency of the output signal (CKIN) of the voltage controlled oscillator (110).
