# Term:Secret Key

## Contents

## FIPS 140-2

Secret Key - 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.

## FIPS 201-1

Secret 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.

## NIST IR 7298

Secret Key - A cryptographic key that is uniquely associated with one or more entities. 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: FIPS 198

## NIST IR 7298

Secret Key - A cryptographic key that is used with a secret key (symmetric) cryptographic algorithm, that is uniquely associated with one or more entities and is not be 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: SP 800-57

## NIST SP 800-116

Secret Key - A key used by a symmetric key algorithm to encrypt, decrypt, sign, or verify information. In a Symmetric Key Infrastructure (SKI), the sender and receiver of encrypted information must share the same secret key.

## NIST SP 800-57P1

Secret Key - A cryptographic key that is used with a secret key (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.

## NIST SP 800-57P2

Secret Key - A cryptographic key that is used with a secret key (also known as a symmetric key) cryptographic algorithm that is uniquely associated with one or more entities and shall not be 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.

## NSA IATF 3-1

Secret Key - A key used by a symmetric algorithm to encrypt and decrypt data.
