A PRNG suitable for cryptographic applications is called a cryptographically-secure PRNG (CSPRNG). A requirement for a CSPRNG is that an adversary not knowing the seed has only negligible advantage in distinguishing the generator's output sequence from a random sequence. In other words, while a PRNG is only required to pass certain statistical tests, a CSPRNG must pass all statistical tests that are restricted to polynomial time in the size of the seed. Though a pr… WebNov 15, 2024 · To directly answer your questions: you must use a CSPRNG when it is specified by the cryptographic algorithm (which is often the case). And you must use a PRNG or a CSPRNG which does not automatically update its inner state when reproducing its output is needed. For the other cases, most of the time which kind of RNG you use …

WebAug 20, 2024 · Pre-shared encryption algorithm simply aim to generate this pad using a seeded method (seed being the key, and CSPRNG's state being the nonce). If you're OK with a limited cycle, then you need to modify the fastest pre-shared encryption algorithm to make it do less work (e.g. smaller block size). WebCSPRNG algorithms are designed so that no polynomial-time algorithm (PTA) can compute or predict the next bit in the pseudo-random sequence, nor is there a PTA that can predict past values of the CSPRNG; these algorithms do not achieve this purpose.

"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.
