  "definition": "1. A (pair-wise) key-establishment procedure whereby one party (i.e., the sender) selects a value for the secret keying material and then securely distributes the value to another party (i.e., the receiver). Contrast with key agreement.\n\n2. Process of exchanging public keys (and other information) in order to establish secure communications.\n\n3. The transport of a key and other keying material from an entity that either owns or generates the key to another entity that is intended to use the key.\n\n4. A key-establishment procedure whereby one party (the sender) selects and encrypts (or wraps) the keying material and then distributes it to another party (the receiver).\nWhen used in conjunction with a public- key (asymmetric) algorithm, the key is encrypted using the public key of the receiver and subsequently decrypted using receiver's private key.\nWhen used in conjunction with a symmetric algorithm, the key is encrypted with a key- wrapping key shared by the sending and receiving parties and decrypted using the same key.\n\n5. A key-establishment procedure whereby one party (the sender) selects a value for the secret keying material and then securely distributes that value to another party (the receiver) using an asymmetric algorithm.\n\n6. See Key transport.\n\n7. A manual or automated key-establishment procedure whereby one entity (the sender) selects and distributes the key to another entity (the receiver).\n\n8. A (pair-wise) key-establishment procedure whereby one party (the sender) selects a value for the secret keying material and then securely distributes that value to another party (the receiver). Contrast with key agreement.\n\n9. A key-establishment procedure whereby one party (the sender) selects a value for the secret keying material and then securely distributes that value to another party (the receiver). Contrast with key agreement.\n\n10. The transport of a key and other keying material from an entity that either owns the key or generates the key to another entity that is intended to use the key.\n\n11. Secure transport of cryptographic keys from one cryptographic module to another module. When used in conjunction with a public key (asymmetric) algorithm, keying material is encrypted using a public key and subsequently decrypted using a private key. When used in conjunction with a symmetric algorithm, key transport is known as key wrapping.\n\n12. The transport of key information from one entity (the sender) to one or more other entities (the receivers). The sender may have generated the key information or acquired it from another source as part of a separate process. The key information may be distributed manually or using automated key transport mechanisms.\n\n13. A key-establishment procedure whereby one party (the sender) selects a value for the secret keying material and then securely distributes that value to another party (the receiver).\n\n14. A key-establishment procedure whereby one party (the sender) selects and encrypts (or wraps) the keying material and then distributes the material to another party (the receiver).\nWhen used in conjunction with a public-key (asymmetric) algorithm, the keying material is encrypted using the public key of the receiver and subsequently decrypted using the private key of the receiver.\nWhen used in conjunction with a symmetric algorithm, the keying material is encrypted with a key-wrapping key shared by the two parties.\n\n15. The transport of a key and other keying material from an entity that either owns, generates or otherwise acquires the key to another entity that is intended to use the key.\n\n16. A key-establishment procedure whereby one party (the sender) selects and encrypts (or wraps) the key and then distributes it to another party (the receiver). When used in conjunction with a public-key (asymmetric) algorithm, the key is encrypted using the public key of the receiver and subsequently decrypted using the receiver’s private key. When used in conjunction with a symmetric algorithm, the key is encrypted with a key-wrapping key shared by the sending and receiving parties and decrypted using the same key.\n\n17. A key-establishment procedure whereby one party (the sender) selects and encrypts the keying material and then distributes the material to another party (the receiver). When used in conjunction with a public-key (asymmetric) algorithm, the keying material is encrypted using the public key of the receiver and subsequently decrypted using the private key of the receiver. When used in conjunction with a symmetric algorithm, the keying material is encrypted with a key-encrypting key shared by the two parties.",
