secret key

Abbreviation(s) and Synonym(s):

Symmetric key

Definition(s):

  A cryptographic key that is used with a (symmetric) cryptographic algorithm that is uniquely associated with one or more entities and is not made public. The use of the term “secret” in this context does not imply a classification level, but rather implies the need to protect the key from disclosure.
Source(s):
CNSSI 4009-2015 from NIST SP 800-57 Part 1 Rev. 3

  A cryptographic key, used with a secret key cryptographic algorithm, that is uniquely associated with one or more entities and should not be made public.
Source(s):
NIST SP 800-12 Rev. 1 under Secret Key

  A cryptographic key used by one or more (authorized) entities in a symmetric-key cryptographic algorithm; the key is not made public.

  A single cryptographic key that is used by one or more entities with a symmetric key algorithm.
Source(s):
NIST SP 800-57 Part 2 Rev.1 under Symmetric key

  A single cryptographic key that is used with a symmetric (secret key) cryptographic algorithm and is not made public (i.e., the key is kept secret). A secret key is also called a symmetric key.
Source(s):
NIST SP 800-175B Rev. 1 under Secret key

  The use of the term “secret” in this context does not imply a classification level, but rather implies the need to protect the key from disclosure.

  Compare with a private key, which is used with a public-key (asymmetric-key) algorithm.
Source(s):
NIST SP 800-175B Rev. 1 under Secret key

  A single cryptographic key that is used with a symmetric (secret key) algorithm, is uniquely associated with one or more entities, and is not made public (i.e., the key is kept secret); a symmetric key is often called a secret key.

  A single cryptographic key that is used with a symmetric-key cryptographic algorithm, is uniquely associated with one or more entities and is not made public (i.e., the key is kept secret). A secret key is also called a Symmetric key. The use of the term “secret” in this context does not imply a classification level but rather implies the need to protect the key from disclosure.

NIST SP 800-57 Part 1 Rev. 5 under Secret key

  A single cryptographic key that is used with a symmetric-key cryptographic algorithm, is uniquely associated with one or more entities, and is not made public (i.e., the key is kept secret). A symmetric key is often called a secret key. See Secret key.
Source(s):
NIST SP 800-57 Part 1 Rev. 5 under Symmetric key

  A cryptographic key that must be protected from unauthorized disclosure to protect data encrypted with the key. The use of the term “secret” in this context does not imply a classification level; rather, the term implies the need to protect the key from disclosure or substitution.
