Initialization vector
(IV)
Integrity (Also
Assurance of Integrity)
Key See cryptographic key.
March, 2007
A vector used in defining the starting point of a cryptographic process.
The property that sensitive data has not been modified or deleted in an
unauthorized and undetected manner.
In this recommendation, the statement that a cryptographic algorithm
"provides integrity" means that the algorithm is used to detect
unauthorized modifications or deletions.
Key agreement A key establishment procedure where resultant keying material is a
function of information contributed by two or more participants, so that
no party can predetermine the value of the keying material independent
of the other party’s contribution.
Key attribute See attribute
Key component See cryptographic key component.
Key confirmation A procedure to provide assurance to one party that another party
actually possesses the same keying material and/or shared secret.
Key de-registration A function in the lifecycle of keying material; the marking of all
keying material records and associations to indicate that the key is no
longer in use.
Key derivation A function in the lifecycle of keying material; the process by which
one or more keys are derived from a shared secret and other
information.
Key distribution The transport of a key and other keying material from an entity that
either owns the key or generates the key to another entity that is
intended to use the key.
Key encrypting key A cryptographic key that is used for the encryption or decryption of
other keys.
Key establishment A function in the lifecycle of keying material; the process by which
cryptographic keys are securely established among cryptographic
modules using manual transport methods (e.g., key loaders), automated
methods (e.g., key transport and/or key agreement protocols), or a
combination of automated and manual methods (consists of key
transport plus key agreement).
Key management The activities involving the handling of cryptographic keys and other
related security parameters (e.g., IVs and passwords) during the entire
life cycle of the keys, including their generation, storage,
establishment, entry and output, and destruction.
Key management
archive
A function in the lifecycle of keying material; a repository containing
keying material of historical interest.
