Abstract

We clarify the notion of a strong prime by supplying a precise definition and a characterization for an optimal strong prime. We present a conjecture regarding the distribution and density of optimal strong primes, allowing one to predict in advance the time needed to compute one optimal strong prime of a given bit length. Based on these results, we develop an algorithm to compute optimal strong primes. Some experimental results are also included.
