Key-derivation key

Term · Cybersecurity · MLC-T-CYB-002384

1. A key used as an input to a key-derivation function to derive additional keying material.

2. As used in this Recommendation, a key that is used during the key-expansion step of a key-derivation procedure to derive the secret output keying material. This key-derivation key is obtained from a shared secret during the randomness-extraction step.

3. A key used as an input to a key-derivation method to derive additional keying material.

4. A key used as an input to a key derivation function to derive other keys.

5. A key used as an input to a key-derivation method to derive other keys. See [NIST SP 800-108].

6. A key that is used as an input to a key derivation function or key expansion function to derive other keys.

7. A key that is used as input to the key expansion step to derive other keys. In this Recommendation, the key derivation key is obtained by performing randomness extraction on a shared secret.

8. See Key-derivation key.

9. A key used with a key-derivation function or method to derive additional keys. Sometimes called a master key.

10. A key used as an input to a key-derivation method to derive other keys. See SP 800-108.

11. A key used with a key-derivation method to derive additional keys. Sometimes called a master key.

12. A key used as an input to a key-derivation method to derive other keys; see SP 800-108.

13. A key used with a key-derivation function or method to derive additional keys. Also called a master key.
