WebJan 11, 2024 · Summary. A pseudo-random number generator (PRNG), if run for long enough, generates a characteristic sequence that is based on its algorithm. This sequence repeats forever and is invariant.

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…
