1. A method of generating a random binary waveform containing events which occur at random intervals, the method comprising:

  • deriving, from a physical noise source, a first preliminary signal containing first events occurring asynchronously and at random intervals; and

    multiplying the first preliminary signal with at least one further preliminary signal containing further events, said at least one further preliminary signal being a deterministic signal, so as to intersperse the first and further events;

    wherein the physical noise source produces a non-deterministic output.
