  "field": "Cybersecurity",
  "definition": "1. In this Recommendation, a key-wrapping key is a symmetric key established through a key-agreement transaction and used with a key-wrapping algorithm to protect the keying material to be transported.\n\n2. A symmetric key-encrypting key that is used to provide both confidentiality and integrity protection. Also see Key-encrypting key.\n\n3. A symmetric key used with a key-wrapping algorithm to protect keying material. In accordance with this Recommendation (SP 800-56B), a key-wrapping key can be established using a KAS1, KAS2 or KTS-OAEP scheme and then used with a key-wrapping algorithm to protect transported keying material. (See Section 9.3.)\n\n4. A symmetric key that is used with a key-wrapping algorithm to protect the confidentiality and integrity of keys.\n\n5. A symmetric key used to provide confidentiality and integrity protection for other keys.\n\n6. A symmetric key that is used to provide both confidentiality and integrity protection for other keys. Also see Key-encrypting key.\n\n7. A key used as an input to a key-wrapping method; see SP 800-38F.\n\n8. In this Recommendation, a key-wrapping key is a symmetric key established during a key-transport transaction and used with a key- wrapping algorithm to protect the keying material to be transported.\n\n9. A symmetric key-encrypting key.",
