DESCRIPTION/FUNCTION


The KG-40/40A is a half-duplex digital device used to provide cryptographic security protection for Navy Link 11 and any data communications meeting Tactical Data Information Link (TADIL) A data standards. It links the computer and the data terminal set. The KG-40A serial configuration (KG-40A-S) is used in the Airborne Tactical Data System (ATDS) and the parallel configuration (KG-40A-P) is used in the Navy Tactical Data System (NTDS).

The KG-40A is a mandatory modified version of the older KG-40, which incorporates variable fill capability. The modification entails replacement of a printed circuit board (motherboard) and the front panel assembly. The KG-40A provides enhanced security using an improved cryptographic algorithm and electronic key capability. Because the KG-40A key is a standard 128-bit key, it can only be keyed by the AN/CYZ-10 Data Transfer Device (DTD) or a KOI-18 Common Fill Device (CFD). It cannot accept key from the KYK-13 Electronic Transfer Device (ETD) or from the KYX-15 Net Control Device (NCD). The KG-40A is an UNCLASSIFIED controlled cryptographic item (CCI) when unkeyed and is interoperable with the KG-40. When the KG-40A is keyed, classification equals that of the key installed.

The KG-40A peripheral equipment includes the MT-4417/S Parallel Mount, MT-4416/A Serial Mount, and KGX-40A Remote Control Unit (RCU).
