The invention relates to a random number generator which comprises a closed-loop inverter chain (10) with inverters (18a, 18b, 18c) connected in series, an output device (12) for outputting a random number that depends on the status between two inverters (18a, 18c) of the closed-loop inverter chain (10), and a processing device (14) for processing a signal between two subsequent inverter chains of the inverters connected in series and for feeding the processed signal to the closed-loop inverter chain. The processing device (14) is configured in such a manner that the processed signal differs from the signal between the two subsequent inverters (18a, 18c). By specifically influencing the closed-loop inverter chain (10), the danger of the periodic scanning by means of the outputting device (12) is reduced, thereby obtaining a high-quality random number generator with reduced chip surface requirements and low power consumption. |
