Term:Cryptographic Key
Contents
FIPS 140-2
Cryptographic Key (Key)- a parameter used in conjunction with a cryptographic algorithm that determines
- the transformation of plaintext data into ciphertext data,
- the transformation of ciphertext data into plaintext data,
- a digital signature computed from data,
- the verification of a digital signature computed from data,
- an authentication code computed from data, or
- an exchange agreement of a shared secret.
FIPS 201-1
Cryptographic Key (Key)- A parameter used in conjunction with a cryptographic algorithm that determines the specific operation of that algorithm.

Cryptographic Key - A value used to control cryptographic operations, such as decryption, encryption, signature generation or signature verification. SOURCE: SP 800-63
NIST SP 800-108
Cryptographic Key - A binary string used as a secret parameter by a cryptographic algorithm. In this Recommendation, a cryptographic key shall be either a truly random binary string of a length specified by the cryptographic algorithm or a pseudorandom binary string of the specified length that is computationally indistinguishable from one selected uniformly at random from the set of all binary strings of that length.
NIST SP 800-38A
Cryptographic Key - A parameter used in the block cipher algorithm that determines the forward cipher operation and the inverse cipher operation.
NIST SP 800-38C
Cryptographic Key - A parameter used in the block cipher algorithm that determines the forward cipher function.
NIST SP 800-63v1.0.2
Cryptographic Key - A value used to control cryptographic operations, such as decryption, encryption, signature generation or signature verification. For the purposes of this document, keys must provide at least 80-bits of protection. This means that it must be as hard to find an unknown key or decrypt a message, given the information exposed to an eavesdropper by an authentication, as to guess an 80-bit random number. See also Asymmetric keys, Symmetric key.
NIST SP 800-67v1.1
Cryptographic Key - A parameter that determines the transformation using DEA and TDEA forward and inverse operations.
NIST SP 800-67
Cryptographic Key - A parameter that determines the transformation using DEA and TDEA forward and inverse operations.
