The KGV-8/8A/8B/8C miniature secure data units (SDUs) are general-purpose, half-duplex, removable, and embeddable communications security (COMSEC) transmission security (TRANSEC) modules that support the implementation of the Joint Tactical Information Distribution System (JTIDS) terminals in ships and aircraft for the Department of the Navy (DON). The user installs the module as a plug-in to the front of the AN/URC-107(V) JTIDS terminal. JTIDS is a high-capacity, secure, jam-resistant, tactical data and voice communications system that provides classified information distribution, relative navigation, and identification capabilities. The KGV-8 Family supports over-the-air rekey and can perform automatic key rollover at the end of the cryptographic period. The KGV-8 Family is intended for integration into a host system that controls its operation (e.g., clock and status indicators). It is interoperable with the KGV-11 family, COMSEC/TRANSEC Integrated Circuit (CTIC) DS-101 Hybrid (CDH), KG-66, KGR-66, KGV-68, KI-37, KGV-15, KGV-13,
and KG-87. It is certified to encrypt and decrypt up to TOP SECRET. It is an UNCLASSIFIED controlled cryptographic item (CCI) when unkeyed. When keyed, its classification equals that of the key installed.

This cryptodevice is also used in the US Navy's Link 16 system.
