  "term": "Key-derivation method",
  "field": "Cybersecurity",
  "definition": "1. As used in this Recommendation, a process that derives secret keying material from a shared secret. This Recommendation specifies both one-step and two-step key-derivation methods.\n\n2. A method used to derive keying material from initial shared secrets and possibly other information.\n\n3. A method by which keying material is derived from a shared secret and other information. A key-derivation method may use a key-derivation function or a key-derivation procedure.\n\n4. A key-derivation function or other approved procedure for deriving keying material.\n\n5. As used in this Recommendation, a method by which secret keying material is derived from a shared secret and other information. A key-derivation method may use a key-derivation function or a key-derivation procedure.",
