Csprng algorithm
A cryptographically secure pseudorandom number generator (CSPRNG) or cryptographic pseudorandom number generator (CPRNG) is a pseudorandom number generator (PRNG) with properties that make it suitable for use in cryptography. It is also loosely known as a cryptographic random … See more The requirements of an ordinary PRNG are also satisfied by a cryptographically secure PRNG, but the reverse is not true. CSPRNG requirements fall into two groups: first, that they pass statistical randomness tests; … See more Santha and Vazirani proved that several bit streams with weak randomness can be combined to produce a higher-quality quasi-random bit stream. Even earlier, John von Neumann proved that a simple algorithm can remove a considerable amount of the bias … See more The Guardian and The New York Times have reported in 2013 that the National Security Agency (NSA) inserted a backdoor into a pseudorandom number generator (PRNG) of NIST SP 800-90A which allows the NSA to readily decrypt material that was encrypted with … See more In the asymptotic setting, a family of deterministic polynomial time computable functions $${\displaystyle G_{k}\colon \{0,1\}^{k}\to \{0,1\}^{p(k)}}$$ for some polynomial p, is a pseudorandom number generator (PRNG, or PRG in some references), if it … See more In the discussion below, CSPRNG designs are divided into three classes: 1. those based on cryptographic primitives such as See more Several CSPRNGs have been standardized.
