Abstract
A device including an oscillator circuit having semiconducting logic elements and switching means for controlling warming and cooling of the circuit and, in that process, causing it to heat or cool in order to generate a random signal at the output of the logic elements. A plurality of devices are for continuously generating random signals, and control elements are for controlling in alternating manner the warming and cooling of the devices.
