Ask HN: What is the best test for statistical randomness? Current choices seem to be NIST SP-800-22, DieHarder and Test U01, all of which certainly overlap. Why is there no battery of tests that includes standards developed by different countries and their obvious biases? |
Breaking crypto RNGs is a subtle enough art that having a standardized set of tests wouldn't actually prove anything useful - it would be like saying "We tried every key in our collection on this new padlock and none of them worked, therefore the padlock is secure."
