A device approved by the National Security Agency as a controlled cryptographic item that embodies a cryptographic logic or other cryptographic design. A CCI component does not perform the entire COMSEC function, and is dependent upon a host equipment or assembly to complete and operate the COMSEC function. Note: CCI component is a collective term and may refer to a single microcircuit, a module, a module set or assembly, a printed circuit board, or any combination of these items.
