DTD-II
Data Transfer Device - this page is a stub

DTD-II, or Data Transfer Device 2, is a portable battery powered computer-device for managing and distributing cryptographic key material, developed in 2015 by Thales Germany at the request of the German Bundesamt für Sicherheit in der Informationstechnik (BSI) 1 in Koblenz (Germany).

The device is intended for use by the German Armed Forces and Government, as well as by NATO sphere countries, and replaces existing fill devices like KYK-13, KOI-18, KSP-1, KLL-1 and (partially) KYX-15. When unkeyed, the DTD-II remains a Controlled Cryptographic Item (CCI).

The device has a 20 x 6 character liquid crystal display (LCD) and a keyboard with 43 keys. It can handle variable length black and red keys, that are protected by means of a Crypto Ignition Key (CIK). Up to 8 users are allowed per device, each of which is allowed an individual CIK and keys.

The DTD-II is housed in a ruggedized die-cast aluminium enclosure and is suitable for use under harsh conditions. It supports three interface types: DS102 – also known as Common Fill Device Interface (CFDI), used for legacy equipment – DS101 (with tagging and data header) and RS232D (for PC applications) all of which are wired via the 6-pin U-229 (ODU) socket on the device [A].
