PROBLEM TO BE SOLVED: To propose a random number generating device or the like capable of generating a random number sequence with enhanced prediction difficulty, using an A/D converter mounted on a general electric device.SOLUTION: A random number generating device 1 generates a random number sequence. The random number generating device 1 includes a &bgr; converter 3 that converts one or more analog signals into one or more digital signals using &bgr; conversion. A repeated operation of &bgr; expansion may be described in mapping of a section dynamical system, and its real numerical value track serves as an attractor. A calculation section 7 uses the &bgr; converter 3 as a random number source, performs a calculation to a plurality of logical values generated by the &bgr; converter 3, and generates a random number sequence. |
