  "term": "Key agreement",
  "field": "Cybersecurity",
  "definition": "1. A (pair-wise) key-establishment procedure in which the resultant secret keying material is a function of information contributed by both participants so that neither party can predetermine the value of the secret keying material independent of the contributions of the other party. Contrast with key transport.\n\n2. A key-establishment procedure where resultant keying material is a function of information contributed by two or more participants, so that no party can predetermine the value of the keying material independently of the other party’s contribution.\n\n3. A (pair-wise) key-establishment procedure in which the resultant secret keying material is a function of information contributed by both participants, so that neither party can predetermine the value of the secret keying material independently from the contributions of the other party. Contrast with key transport.\n\n4. A key-establishment procedure where the resultant keying material is a function of information contributed by two or more participants, so that an entity cannot predetermine the resulting value of the keying material independently of any other entity’s contribution.\n\n5. A (pair-wise) key-establishment procedure in which the resultant secret keying material is a function of information contributed by both participants, so that neither party can predetermine the value of the secret keying material independently from the contributions of the other party. Contrast with key-transport.\n\n6. A key-establishment procedure where resultant keying material is a function of information contributed by two or more participants, so that no party can predetermine the value of the keying material independently of any other party’s contribution.\n\n7. A (pair-wise) key-establishment procedure in which the resultant secret keying material is a function of information contributed by both participants so that neither party can predetermine the value of the secret keying material independently from the contributions of the other party. Key agreement includes the creation (i.e., generation) of keying material by the key-agreement participants. A separate distribution of the generated keying material is not performed. Contrast with Key transport.\n\n8. A (pair-wise) key-establishment procedure where the resultant secret keying material is a function of information contributed by two participants so that no party can predetermine the value of the secret keying material independently from the contributions of the other party. Contrast with key-transport.\n\n9. A (pair-wise) key-establishment procedure in which the resultant secret keying material is a function of information contributed by both participants, so that neither party can predetermine the value of the secret keying material independently of the contributions of the other party. Contrast with key transport.\n\n10. A (pair-wise) key-establishment procedure where secret keying material is generated from information contributed by two participants so that no party can predetermine the value of the secret keying material independently from the contributions of the other party. Contrast with key-transport.\n\n11. A key-establishment procedure where keying material is generated from information contributed by two or more participants so that no party can predetermine the value of the keying material independently of any other party’s contribution.\n\n12. A (pair-wise) key-establishment procedure in which the resultant secret keying material is a function of information contributed by both participants so that neither party can predetermine the value of the secret keying material independently of the contributions of the other party; contrast with key transport.\n\n13. A (pair-wise) key-establishment procedure where the resultant secret keying material is a function of information contributed by two participants, so that no party can predetermine the value of the secret keying material independently from the contributions of the other party.
