WebA cryptographic DRBG has the additional property that the output is unpredictable given that the seed is not known. A DRBG is sometimes also called a pseudo-random number generator (PRNG) or a deterministic random number generator. Source (s): NIST SP 800-57 Part 1 Rev. 5 under Deterministic random bit generator (DRBG) WebA PRNG is a single point of failure for many real-world cryptosystems. An attack on the PRNG can make irrelevant the careful selection of good algorithms and protocols. 3. Many systems use badly-designed PRNGs, or use them in ways that make various attacks easier than they need be.

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). WebOne example of an RNG architecture is to seed a cryptographic quality pseudorandom number generator (PRNG) with an unknown seed value and then use the PRNG for a period of time or to produce a quantity of random data. The PRNG will then be re-seeded and used again for a while, and so on. The seed for the PRNG should be a secret, random input ...
