  "term": "Entropy Source",
  "field": "Cybersecurity",
  "definition": "1. The combination of a noise source, health tests, and optional conditioning component that produce bitstrings containing entropy.\n\n2. A physical source of information whose output either appears to be random in itself or by applying some filtering/distillation process. This output is used as input to either a RNG or PRNG.\n\n3. A combination of a noise source (e.g., thermal noise or hard drive seek times), health tests, and an optional conditioning component. The entropy source produces random bitstrings to be used by an RBG.\n\n4. The combination of a noise source, health tests, and an optional conditioning component that produce random bitstrings to be used by an RBG.",
