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 number generator (CRNG) (see Random number generation § "True" vs. pseudo-random numbers).

WebJan 6, 2015 · $\begingroup$ PRNG encompasses all pseudo random number generators, from the horrible rand call in c, over suitable for simulations but not security ones like the mersenne twister, to the most secure cryptographic PRNG. CSPRNGs are simply the subset of PRNGs which are secure. Every stream cipher, including AES-CTR can act as CSPRNG. … WebDescription The product uses a Pseudo-Random Number Generator (PRNG) in a security context, but the PRNG's algorithm is not cryptographically strong. Extended Description …

WebThe distance (in digits or bits) between repetition’s is the algorithm output period. The longer the period the better the more effective the PRNG (James, 1990; Ripley, 1990). Uniformity – In cryptographic applications, the output of a PRNG will most likely be represented in binary format. There should be an equal number of 1’s and 0’s ...
