Randomizer Quality Test

Randomizer Quality Test

Method of Testing a Randomizer

This technology tests the sufficiency of the output from a random number generator (or randomizer) by taking samples of the data from within the randomizer, going beyond traditional randomness tests that use the output from the randomizer. More than just a “pass/fail” tester, which can produce false positives, this technology shows designers how to improve or fix the design of the randomizer in order to present sufficiently random results.
