WebJul 30, 2016 · A TRNG provides unpredictable output by physical means. An entropy source is one that provides unpredictable output; the entropy is a measure of how unpredictable. Hardware entropy sources are rarely uniform, so they should never be used as an RNG, but as a seed to a CSPRNG, i.e. a deterministic algorithm that “smoothen” all correlations ...
