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.

WebAug 6, 2016 · There is no known method to predict decay so, yes, that is by definition cryptographically secure. Such things are considered true randomness, as opposed to the pseudo-randomness that we generate with our pseudo-random number generators (algorithms). The caveat is that you have to use the true random source properly. WebLike a PRNG, a CSPRNG needs random data (the cryptographic seed) as a starting point from which to produce more random data.
