WebIf you want a lot of pseudorandomness with a very high bandwidth, you should look at specialized stream ciphers like these ones (a stream cipher can be turned into a PRNG by making it encrypt a long sequence of zeros). 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.

WebApr 13, 2016 · CSPRNG s have certain properties that make them suitable for use in security: Every CSPRNG should satisfy the next-bit test. That is, given the first k bits of a random sequence, there is no polynomial-time algorithm that can predict the (k+1)th bit with probability of success better than 50%.

WebNov 15, 2024 · A CSPRNG is a cryptographically secure PRNG. It is a PRNG, with some strong requirements. In your link, the author is writing about CSPRNGs, but calling them PRNGs. The "cryptographically secure" element is implied by this requirement: The generated bit strings should "look random" to an adversary. WebFor a value to be cryptographically secure, it must be impossible or highly improbable for an attacker to distinguish between it and a truly random value. In general, if a PRNG algorithm is not advertised as being cryptographically secure, then it is probably a statistical PRNG and should not be used in security-sensitive contexts. Examples WebMay 21, 2024 · Basic PRNGs are designed for simulations while CSPRNG are designed for cryptography.

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…
