KG - 66 |
KG-66/66A is a half-duplex, serial, synchronous, binary, digital key generator used to encrypt telemetry or digital data in air-to-ground communications links. The KG-66A is an upgraded, fully interoperable version of the KG-66. The KUTA/NOBLEMAN family is interoperable with the KG-67, KG-135, and SO-66 (Mode B only), and accepts key via the AN/CYZ-10, KOI-18, KYK-13, or KYX-15A. It is certified to encrypt/decrypt up to SECRET; however, two devices can be used in an upgrade configuration to achieve a higher level of classification. KUTA/NOBLEMAN units are UNCLASSIFIED controlled cryptographic item (CCI) when unkeyed. When keyed, their classification equals that of the key installed.
