As we're discussing the roadmap for a new GSL, I'd like to offer up at least two, maybe three more random number generators for inclusion in the GSL list that have been contributed and integrated into dieharder. One that I think should absolutely be there is rng_aes -- basically an implementation of AES as a random number generator. AES is cryptographic grade random and is arguably very close to a "gold standard" that can be used to test random number generator testers, as there is always an unstated addition to the null hypothesis "Assuming that this is a perfect random number generator AND that this is a valid test...", and failure of the latter is very difficult to discriminate from failure of the former without at least a few generators for which failure of the former is arguably less likely than failure of the latter. rng_threefish does the same thing on top of many rounds of skein. I was using aespipe to feed dieharder in a pipe until these were contributed, but having them integrated is worthwhile, especially given that rng_aes is respectably fast, around 1/5 the speed of mt19937. rgb Robert G.
