WebPseudo-Random Number Generators. We want to be able to take a few "true random bits" (seed) and generate more "random looking bits", i.e. construct a function G: { 0, 1 } t → { 0, 1 } T, T ≫ t . The generated bit strings should "look random" to an adversary. In cryptography, PRNG’s are used to construct session keys and stream ciphers. WebApr 14, 2024 · The NIST Special Publication (SP) 800-90 series supports the generation of high-quality random bits for cryptographic and non-cryptographic use.
