How to Predict the Output of a Hardware Random Number Generator

Markus Dichtl

Abstract: A hardware random number generator was described at CHES 2002 by T. Tkacik. In this paper, we analyze its method of generating randomness and, as a consequence of the analysis, we describe how, in principle, an attack on the generator can be executed.
