  "definition": "1. 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.\n\n2. An RBG that includes a DRBG mechanism and (at least initially) has access to a source of entropy input.
