The paper deals with true random number generators using a set of ring oscillators as proposed by Sunar et al. in 2007. The original generator has been recently enhanced by Wold and Tan by introducing flip-flops at the output of each ring. We show in the first part of the paper that both original and enhanced architectures have exactly the same behavior when composed of ideal components (they have the same mathematical model), but they have very different behavior in physical devices, as… CONTINUE READING
