2 (D)

"Sequence of bits transmitted over a communications system for synchronizing cryptographic equipment." [C4009]

Deprecated Term: IDOCs SHOULD NOT use this term as a synonym for "initialization value"; the term mixes concepts in a potentially misleading way. The word "message" is misleading because it suggests that the mechanism is specific to electronic mail. (See: Message Handling System.)
