NIST IR 7298 Revision 1, Glossary of Key Information Security Terms
Key Management Infrastructure –
(KMI)
All parts – computer hardware, firmware, software, and other
equipment and its documentation; facilities that house the equipment
and related functions; and companion standards, policies, procedures,
and doctrine that form the system that manages and supports the
ordering and delivery of cryptographic material and related
information products and services to users.
SOURCE: CNSSI-4009
Key Pair – Two mathematically related keys having the properties that (1) one
key can be used to encrypt a message that can only be decrypted
using the other key, and 2) even knowing one key, it is
computationally infeasible to discover the other key.
SOURCE: SP 800-32
Key Pair – A public key and its corresponding private key; a key pair is used
with a public key algorithm.
SOURCE: SP 800-21; CNSSI-4009
Key Production Key (KPK) – Key used to initialize a keystream generator for the production of
other electronically generated key.
SOURCE: CNSSI-4009
Key Recovery – Mechanisms and processes that allow authorized parties to retrieve
the cryptographic key used for data confidentiality.
SOURCE: CNSSI-4009
Key Stream – Sequence of symbols (or their electrical or mechanical equivalents)
produced in a machine or auto-manual cryptosystem to combine with
plain text to produce cipher text, control transmission security
processes, or produce key.
SOURCE: CNSSI-4009
Key Tag – Identification information associated with certain types of electronic
key.
SOURCE: CNSSI-4009
Key Tape – Punched or magnetic tape containing key. Printed key in tape form
is referred to as a key list.
SOURCE: CNSSI-4009
Key Transport – The secure transport of cryptographic keys from one cryptographic
module to another module.
SOURCE: FIPS 140-2; CNSSI-4009
