HAYFIELD MULTI-CHIP MODULE
PROG/PROJ ELEMENT: 33401N
The HAYFIELD MCM is a programmable four-channel receive-only device developed for receivers used to decrypt the Tactical Receive Equipment and Related Applications (TRAP) Data Dissemination System (TDDS) broadcast. It incorporates DS-102 and DS-101 key loading and is Electronic Key Management System (EKMS) compatible. It has internal storage for six algorithms and 64 keys and is capable of performing over-the-air rekey (OTAR). The HAYFIELD MCM is packaged in a 160-pin quad flat pack. The initial application is for the KGR-96 function only, but other algorithms are being developed in software for incorporation into HAYFIELD. These include the KGV-11 function, the KG-84 function for secondary imagery reception, and the KG-40A function (High Speed Fleet Broadcast).
The HAYFIELD MCM is certified to decrypt traffic TOP SECRET/SI and below. The HAYFIELD is an UNCLASSIFIED controlled cryptographic item (CCI) when unkeyed. When keyed, it carries the classification level of the traffic key loaded into the host equipment.
The HAYFIELD MCM is currently used on the KGV-113 COMSEC board and installed in the Multi-Mission Advanced Tactical Terminal (MATT).
