Abstract:
A device (1) for generating a random bit sequence has a digital ring oscillator circuit (2) having at least one first feedback path (R8) and one second feedback path (R14). To this end, a changeover is performed between the feedback paths (R8, R14) at times which can be predetermined, and a random signal (OS) having a random level history can be tapped at an output node (4) of the ring oscillator circuit (2).
