Datakey is a manufacturer of rugged portable data carriers (memories) and receptacles, based in Savage (Minnesota, USA). Their devices or tokens are used for a variety of applications, including Crypto Ignition Keys (CIKs), Traffic Encryption Keys (KEKs), PKI tokens, biometrics data, Secure Data Transfer, etc., by commercial parties as well as by the US Department of Defence (DoD).

The company was founded by Bill Flies 1 and was incorporated on 27 April 1976. The idea for a portable erasable memory device was born after he saw people writing down passwords on a piece of paper. The company's first product was the ill-fated DK1400, soon followed by the improved DK1401. Millions of memory keys and tokens have since been used at the heart of military cryptographic products, and in medical, industrial and commercial products [2].

On 14 December 2010, Datakey was taken over by ATEK Products, LLC, and has since been operating as Datakey, a division of ATEK Products (now: ATEK Access Technologies). The name Datakey is now used as a brand name for the range of tokens and key storage devices.

KSD-64   PK-64KC
KSD-64 was a Key Storage Device developed especially for the US National Security Agency (NSA). It was used with a range of (voice) encryption devices, such as the STU-III secure telephones and the Saudi Piece Shield.

The device features a 64Kb EEPROM with parallel interface, and was replaced by the compatible (but now end-of-life) Parallel Key PK-64KC.

DK-1000   DK1Kb
DK-1000, also: DK1Kb, is a 1Kb EEPROM with Microwire interface. It is used as a Crypto Ignition Key (CIK) with devices like the KIV-7 — the embeddable KG-84 COMSEC module.

The DK-1000 has a fully redundant contact arrangement, which means that it can be inserted either way around.

PKS-703 Keyloader
PKS-703 is a transfer device for KSD-64 and PK-64Kx memory tokens. With the right software it can be used as a key loader.

The device has a Keyceptacle for Datakey PK-series tokens and an internal microprocessor platform that can be used to read and write PK tokens. Access it through a serial RS232 port.
