  "term": "Key-derivation procedure",
  "field": "Cybersecurity",
  "definition": "1. A procedure consisting of multiple steps and using an approved algorithm (e.g., a MAC algorithm) by which keying material is derived from a shared secret and other information.\n\n2. As used in this Recommendation, a multi-step process to derive secret keying material from a shared secret and other information.\n\n3. As used in this Recommendation, a two-step key-derivation method consisting of randomness extraction followed by key expansion.\n\n4. A multi-step process that uses an approved Message Authentication Code (MAC) algorithm to derive keying material from a shared secret and other information.",
