WebIn 1987, Stern showed how the parameters for secret truncated linear congruential generators could be derived in polynomial time. Here, we present a modification to that algorithm which makes it simpler, more robust, and require less data. We then present a more careful analysis of the algorithm, and establish some limits of its applicability.
