The KIK-20 Secure DTD2000 System (SDS) is a key fill device developed by Sypris Electronics, Florida, US, under the auspices of the U.S. National Security Agency. It, along with the AN/PYQ-10, is intended to eventually replace the AN/CYZ-10 key fill device, along with older units still in service, and can support a wide variety of cryptographic devices and key types.
The SDS is roughly the same size as the CYZ-10 — 7.4" (188mm) x 4.25" (108) x 1.8" (46mm) — and weighs less than 2.5 lbs (1.1 kg). It uses an XScale processor running at 300 MHz under the Microsoft Windows CE operating system. Cryptographic functions are performed by an internal KOV-21 crypto PC Card. The SDS includes 64 MB of RAM, 32 MB of flash read-only memory, a QWERTY keyboard, half-VGA color display, and a USB port. It also has a 6-pin connector for cabling to NSA standard fill connectors. The keyboard includes two zeroize buttons. It costs US$3700 each.
