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… WebJan 19, 2024 · I have a (likely incomplete) understanding of what it takes to make a cryptographically secure PRNG - for example I know that resistance to predictability or backtracking matters, ideally resistance that stays strong even as the attacker learns more outputs of the PRNG or learns bits of the PRNG's internal state.
