WebNov 15, 2024 · A CSPRNG is a cryptographically secure PRNG. It is a PRNG, with some strong requirements. In your link, the author is writing about CSPRNGs, but calling them PRNGs. The "cryptographically secure" element is implied by this requirement: The generated bit strings should "look random" to an adversary. WebThere are two types of PRNGs: statistical and cryptographic. Statistical PRNGs provide useful statistical properties, but their output is highly predictable and forms an easy to reproduce numeric stream that is unsuitable for use in cases where security depends on generated values being unpredictable.

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…
