  "id": "MLC-T-CYB-002325",
  "term": "Key derivation",
  "field": "Cybersecurity",
  "definition": "1. The process by which keying material is derived from 1) either a cryptographic key or a shared secret produced during a key-agreement scheme and 2) other data. This Recommendation specifies key derivation from an existing cryptographic key and other data.\n\n2. The process that derives keying material from a key.\n\n3. 1. A process by which one or more keys are derived from a shared secret and other information during a key agreement transaction.\n\n4. 2. A process that derives new keying material from a key (i.e., a key-derivation key) that is currently available.\n\n5. The process of deriving a key in a non-reversible manner from shared information, some of which is secret.\n\n6. A process that derives keying material from a key or a shared secret.\n\n7. The process by which one or more keys are derived from either a pre-shared key or a shared secret (from a key-agreement scheme), along with other information.\n\n8. As used in this Recommendation, a method of deriving keying material from a pre-shared key and possibly other information. See NIST SP 800-108.\n\n9. A process by which one or more keys are derived from a shared secret and other information during a key-agreement transaction.\n\n10. A process that derives new keying material from a key (i.e., a key-derivation key) that is currently available.\n\n11. The process by which keying material is derived from either a pre-shared key or a shared secret produced during a key-agreement scheme along with other information.\n\n12. The process by which keying material is derived from either a pre-shared key or a shared secret (from a key-agreement scheme), along with other information.\n\n13. A function in the lifecycle of keying material; the process by which one or more keys are derived from either a pre-shared key, or a shared secret and other information.",
