Random Bit Generator (RBG)

Abbreviation(s) and Synonym(s):

RBG

Definition(s):

  A device or algorithm that outputs a sequence of binary bits that appears to be statistically independent and unbiased. An RBG is either a DRBG or an NRBG.
Source(s):
NIST SP 800-90A Rev. 1

  A device or algorithm that outputs bits that are computationally indistinguishable from bits that are independent and unbiased.
Source(s):
NIST SP 800-133

  A device or algorithm that outputs a random sequence that is effectively indistinguishable from statistically independent and unbiased bits. An RBG is classified as either a DRBG or an NRBG.
