  "term": "Key wrapping",
  "field": "Cybersecurity",
  "definition": "1. A method of encrypting and decrypting keys and (possibly) associated data using a symmetric key; both confidentiality and integrity protection are provided.\n\n2. A method of cryptographically protecting keys using a symmetric key that provides both confidentiality and integrity protection.\n\n3. In this Recommendation, key-wrapping is a method of protecting keying material using a symmetric-key-based authenticated encryption method, such as a block cipher key-wrapping mode specified in [NIST SP 800-38F] that provides both confidentiality and integrity protection.\n\n4. Encrypting a symmetric key using another symmetric key (the key encrypting key). A key used for key wrapping is known as a key encrypting key.\n\n5. A method of protecting secret keying material (along with associated integrity information) that provides both confidentiality and integrity protection when using symmetric-key algorithms.\n\n6. A method of providing both confidentiality and integrity protection for keying material using a symmetric key,\n\n7. A method of encrypting and decrypting keys and (possibly) associated data using symmetric-key cryptography; both confidentiality and integrity protection are provided. See SP 800-38F. 6\n\n8. A method of cryptographically protecting the confidentiality and integrity of keys using a symmetric-key algorithm.\n\n9. A method of encrypting and decrypting keys and (possibly) associated data using symmetric-key cryptography; both confidentiality and integrity protection are provided; see SP 800-38F.\n\n10. A method of protecting keying material (along with associated integrity information) that provides both confidentiality and integrity protection when using a symmetric-key algorithm.\n\n11. A method of encrypting keys (along with associated integrity information) that provides both confidentiality and integrity protection using a symmetric key.",
