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… WebIf the application requires PRNG engines of cryptographic quality but not of true randomness, QRandomGenerator::system() may still be used (see section below). If neither a true RNG nor a cryptographically secure PRNG are required, applications should instead use PRNG engines like QRandomGenerator 's deterministic mode and those from the C++ ... earls citrus

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.

WebNov 5, 2024 · By the definition of a cryptographically secure PRNG on Wikipedia, given part or all of the internal state, an adversary should not be able to reconstruct the prior stream of random numbers.
