We have been asked by a customer if we have any tests that demonstrate the randomness of the SSLeay random number generator (augmented by some sound-card random number seeding that we wrote).
I'd like to find some standard implementation for testing randomness, but Schneier offers no help (other than a reference to Knuth Vol 2), and I don't know where else to turn.
I realise that cryptographic randomness requires unpredictability, and this quality depends upon closed-world assumptions about unknown individuals' predictive powers, but we have to live with that.
* Marsaglia's DIEHARD suite, also see DIEHARDC * I posted code for Maurer's Universal statistical test a week or so ago; I find this discriminates between a cipher output and real noise... * Find the RAND corp paper on random numbers * See FIPS 140
