Deterministic Random Bit Generator

Abbreviations / Acronyms / Synonyms:

Deterministic random bit generator (DRBG)
deterministic random number generator
Pseudorandom Number Generator
Pseudorandom number generator (PRNG)
Pseudo-random Number Generator (PRNG)

Definitions:

  See Deterministic random bit generator (DRBG).
Sources:
NIST SP 800-57 Part 1 Rev. 5 under Pseudorandom number generator (PRNG)

  See Deterministic Random Bit Generator.
Sources:
NIST SP 800-90A Rev. 1 under Pseudorandom Number Generator

  A random bit generator that includes a DRBG algorithm and (at least initially) has access to a source of randomness. The DRBG produces a sequence of bits from a secret initial value called a seed. A 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.

NIST SP 800-57 Part 1 Rev. 5 under Deterministic random bit generator (DRBG)

  An RBG that includes a DRBG mechanism and (at least initially) has access to a randomness source. The DRBG produces a sequence of bits from a secret initial value called a seed, along with other possible inputs. A DRBG is often called a Pseudorandom Number (or Bit) Generator. Contrast with NRBG.

  An RBG that includes a DRBG mechanism and (at least initially) has access to a source of entropy input. The DRBG produces a sequence of bits from a secret initial value called a seed, along with other possible inputs. A DRBG is often called a Pseudorandom Number (or Bit) Generator.
