The security challenges confronting Department of the Navy information technology resources are multiplying rapidly with the exponential growth of interconnected systems for producing and exchanging data and information. As interconnectivity increases and the threats to information technology become more sophisticated and diverse, Department of the Navy systems become inherently more vulnerable to surreptitious access and malicious attacks. The fast-paced advances of technology drive Department of the Navy reliance on commercial technologies and services; however, many of these solutions may offer only minimal defense against the Information Warfare threat activity and must be augmented by Information Systems Security disciplines and focused management decisions to ensure protection of DoN information technology resources.

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).
National Security Agency (NSA) has determined that this product does not process, store, or utilize a date in its operations. Therefore, the year 2000 problem does not affect this product; NSA memo of 12 Jun 98 applies.
