High-end embeddable encryption module
- this page is a stub
RedFox is a universal high-end proprietary encryption/decryption module,
developed around 2005 by Fox-IT
in Delft (Netherlands) on behalf of the Dutch Government. It has
full red-black separation and can be embedded in existing products.
RedFox is the successor to the
Fort Fox File Encryptor (FFFE) PCMCIA card
and is suitable for securing data (storage)
as well as IP links.
|
RedFox was developed in close cooperation with the NBV
— the NLNCSA of the Dutch
General Intelligence and Security Service AIVD.
It is used in a special version of the well-known
SINA Box network encryptor,
known as SINA RedFox [3].
In 2014 it was announced that Fox-IT was commissioned by the
Dutch Ministry of Defense (MoD) for the development of a new
Electronic Key Management System (EKMS), at the heart of
which the RedFox Crypto Module would be used [5][6].
As part of the EKMS, 400 Electronic Fill Devices (EFD) would
be provided by Fox-IT [6].

Due to the classified nature of the RedFox Crypto Module, we are
currently unable to show a picture of the module or its crypto chip.
As far as we know, there are no images of this module in the public
domain.

Between 1997 and 2001, the Dutch manufacturer Philips Usfa
(later: Philips Crypto) developed a hardware-based
encryption module for the Dutch Government.
The module was based on a PCMCIA card that
could be plugged into the laptop computers of the era and, with an
adapter, in regular personal computers (PCs). Inside the PCMCIA
card was a Philips-developed crypto chip known as the
General Crypto Device Philips (GCD-PHI), generally known as the
GCD-Φ chip.
The product met with several setbacks, delays and specification changes
by the customer, and was finally cancelled by the Dutch Government in
2001, although Philips Crypto had meanwhile developed
several successful products based on the
GCD-Φ chip
and the later GCD-Φ 2000.
After Philips Crypto closed down in 2003, its assets
and product portfolio were taken over by two other Dutch companies:
Compumatica in Uden (Netherlands) and
Fox-IT in Delft (Netherlands).
Compumatica took over the
LAN Guard network encryptor.
The remains of the ill-fated
V-Kaart project went to
Fox-IT, where the software was completely
rewritten. The product was renamed
Fort Fox File Encryptor (FFFE) and was successfully
sold to the Dutch Government for many years.
Immediately after the introduction of the
FFFE card, Fox-IT
started the development of the next generation of crypto chips
and crypto modules.
After a successful evaluation by the AIVD/NBV –
the Dutch Security Agency – the new RedFox chip was announced in 2005 [5].
Products based on RedFox were expected during the 2nd half of 2012, subject
to approval by the NLNCSA (NBV) [2].
RedFox is available for (civil) third parties and contains a number
of standard algorithms for Public
Key Encryption (PKE), such as AES, SHA-256 and SHA-512.
A special version of the chip, called RedFox GT, contains
classified algorithms and is available for the Dutch Government only.
