NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Cryptographic Alarm – Circuit or device that detects failures or aberrations in the logic or operation of crypto-equipment. Crypto-alarm may inhibit transmission or may provide a visible and/or audible alarm. SOURCE: CNSSI-4009 Cryptographic Algorithm – A well-defined computational procedure that takes variable inputs, including a cryptographic key, and produces an output. SOURCE: SP 800-21; CNSSI-4009 Cryptographic Ancillary Equipment – Equipment designed specifically to facilitate efficient or reliable operation of cryptographic equipment, without performing cryptographic functions itself. SOURCE: CNSSI-4009 Cryptographic Binding – Associating two or more related elements of information using cryptographic techniques. SOURCE: CNSSI-4009 Cryptographic Boundary – An explicitly defined continuous perimeter that establishes the physical bounds of a cryptographic module and contains all the hardware, software, and/or firmware components of a cryptographic module. SOURCE: FIPS 140-2 Cryptographic Component – Hardware or firmware embodiment of the cryptographic logic. A cryptographic component may be a modular assembly, a printed wiring assembly, a microcircuit, or a combination of these items. SOURCE: CNSSI-4009 Cryptographic Equipment – Equipment that embodies a cryptographic logic. SOURCE: CNSSI-4009 Cryptographic Hash Function – A function that maps a bit string of arbitrary length to a fixed length bit string. Approved hash functions satisfy the following properties: 1) (One-way) It is computationally infeasible to find any input which maps to any pre-specified output, and 2) (Collision resistant) It is computationally infeasible to find any two distinct inputs that map to the same output. SOURCE: SP 800-21 Cryptographic Ignition Key (CIK) – Device or electronic key used to unlock the secure mode of cryptoequipment. SOURCE: CNSSI-4009 Pg 52
NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Cryptographic Initialization – Function used to set the state of a cryptographic logic prior to key generation, encryption, or other operating mode. SOURCE: CNSSI-4009 Cryptographic Key – A value used to control cryptographic operations, such as decryption, encryption, signature generation, or signature verification. SOURCE: SP 800-63 A binary string used as a secret parameter by a cryptographic algorithm. SOURCE: SP 800-108 Cryptographic Key – A parameter used in conjunction with a cryptographic algorithm that determines the specific operation of that algorithm. SOURCE: FIPS 201; FIPS 198 Cryptographic 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. SOURCE: FIPS 140-2 Cryptographic Logic – The embodiment of one (or more) cryptographic algorithm(s) along with alarms, checks, and other processes essential to effective and secure performance of the cryptographic process(es). SOURCE: CNSSI-4009 Cryptographic Material – (slang CRYPTO) COMSEC material used to secure or authenticate information. SOURCE: CNSSI-4009 Cryptographic Module – The set of hardware, software, firmware, or some combination thereof that implements cryptographic logic or processes, including cryptographic algorithms, and is contained within the cryptographic boundary of the module. SOURCE: SP 800-32; FIPS 196 Cryptographic Module – The set of hardware, software, and/or firmware that implements Approved security functions (including cryptographic algorithms and key generation) and is contained within the cryptographic boundary. SOURCE: FIPS 140-2 Pg 53
