KG - 194 |
The KG-94 and KG-194 are tactical versions of the KG-94A and KG-194A.
The KG-194 is an upgraded version of the KG-94 design. All verions are
cryptographically compatible with each other, as well as with the KG-81 and
KG-95 within their respective data rates in the traditional key mode. When
used in conjunction with the Interface Adapter Unit, they can be a direct
replacement for the KG-27. The KG-194 and 194A are interoperable only with
other KG-194(A) in the FIREFLY mode. The KG-94 and KG-194 family functions
with MIL-STD 118/114, RS-422 and RS-449 standard synchronous interfaces.
Encryption and decryption takes place at speeds of 9.6 Kbps to 13 Mbps.
The KG-194 and 194A generators are compatible with FIREFLY remote re-keying
and can also be keyed with the KSD-64A. Traditional keying is accomplished
with the KOI-18, KYK-13, KYK-15, KOK-12, and the Data Transfer Device
(AN/CYZ-10) for any of the KG-94s and 194s. The KG-94 and 194 families may
be used with fix plant and tactical trunk encryption devices. They are
approved for use at all classification levels up to TOP SECRET. They are
UNCLASSIFIED controlled cryptographic items (CCIs) when unkeyed.
KG-81: Provides full-duplex encryption of digital trunks. It is rack
mounted using the HNF-81-1/2
interconnect housing frame. The KG-81 is used primarily at major
communications stations for bulk
data and video encryption.
KG-94: Provides emerging low and medium tactical and nontactical
digital trunk encryption. It is
rack mounted using the HNF-81-1/2 interconnect housing frame and supports
the Joint Tactical
Communications program in association with Marine Corps AN/TTC-42 and
AN/TRC-170 switches.
