  "definition": "1. An RBG that always has access to an entropy source and (when working properly) produces output bitstrings that have full entropy. Often called a True Random Number (or Bit) Generator. (Contrast with a deterministic random bit generator).\n\n2. An RBG that always has access to an entropy source and (when working properly) produces outputs that have full entropy (see SP 800-90C). Also called a true random bit (or number) generator (Contrast with a DRBG).",
