The AN/CYZ-10 Data Transfer Device
, often called a Filler
, Crazy 10
, is a United States National Security Agency
-developed, portable, hand-held fill device
, for securely receiving, storing, and transferring data between compatible cryptographic and communications equipment. It is capable of storing 1,000 keys
, maintains an automatic internal audit trail of all security-relevant events that can be uploaded to the LMD/KP
, encrypts key for storage, and is programmable. The DTD is capable of keying multiple information systems security (INFOSEC
) devices and is compatible with such COMSEC
equipment as Single Channel Ground and Airborne Radio System (SINCGARS
) radios, KY-57
, and others that are keyed by common fill devices (CFDs).
The DTD weighs about 4 lb (1.8 kg) and is designed to be fully compatible with future INFOSEC equipment meeting DS-101 signaling and benign fill standards. It will eventually replace the legacy family of CFDs, including the KYK-13, KYX-15 electronic storage devices, and the KOI-18 paper tape reader. Note that only the DTD and the KOI-18 support newer, 128-bit keys.
As of mid-2005, refurbished units cost $4000 each.
The DTD is slated to be replaced by the AN/PYQ-10 Simple Key Loader (SKL) and the Secure DTD2000 System (or SDS), a similarly sized unit that employs the Windows CE operating system. The SDS is currently (2006) beginning production.
