Chaotic physical true random number generator and associated method

Résumé

A chaotic physical true random number generator and the generation method associated therewith. The generator includes a resonator 2, an analog-to-digital converter configured to convert an analog signal originating from the resonator into a digital signal 104, a digital processing device configured to generate a sequence of true random numbers on the basis of the digital signal 104, and a device for exciting the resonator configured to excite the resonator with a determined excitation signal to set it in a dynamic multi-stability mode, and modulate the excitation signal, so that the resonant physical component has a chaotic behaviour and that the analog signal is representative of the chaotic behaviour of the resonator. A gain in terms of simplicity of implementation, bulk and/or manufacturing cost is thus achieved for making physical true random number generators in one or more embodiments.
