Latest … A PRNG suitable for cryptographic applications is called a cryptographically-secure PRNG (CSPRNG). A requirement for a CSPRNG is that an adversary not knowing the seed has only negligible advantage in distinguishing the generator's output sequence from a random sequence. In other words, while a PRNG is only required to pass certain statistical tests, a CSPRNG must pass all statistical tests that are restricted to polynomial time in the size of the seed. Though a pr…

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.
