Abstract

A random number generating device (30) includes: a microcomputer (50); a first oscillator circuit (52) that has a predetermined temperature characteristic and generates a clock serving as a basis of a behavior of the microcomputer (50); and an electronic circuit (54, 60) that has a temperature characteristic being different from the predetermined temperature characteristic of the first oscillator circuit (52) and operates in accordance with a command from the microcomputer (50). The microcomputer (50) measures an operating time of the electronic circuit (54, 60) based upon the clock generated by the first oscillator circuit (52) and generates a random number based upon a result of the measurement.
