  "term": "Entropy rate",
  "field": "Cybersecurity",
  "definition": "The rate at which a digitized noise source (or entropy source) provides entropy; it is computed as the assessed amount of entropy provided by a bitstring output from the source, divided by the total number of bits in the bitstring (yielding the assessed bits of entropy per output bit). This will be a value between zero (no entropy) and one.",
