The convenience of external hard drive and portable
storage applications have also introduced an increasing risk of
exposing sensitive data. To safe guard the sensitive confidential
and personal information, many private and public organizations
have implemented various software and hardware encryption. Most
software or hardware data encryption products in the market are
based on the industry standard proven data encryption algorithms
- DES (Data
Encryption Standard), TDES
(Triple DES) and AES
(Advanced Encryption Standard) that are certified by NIST (National
Institute of Standards and Technology) of USA and CSE (Communications
Security Establishment) of Canada. To learn more detail on data
encryption and its various industrial standards, please visit the

Addonics hardware
encryption solution, the Diamond Cipher, Saturn Cipher, Jupiter Cipher hard drive kits and the Cipher UDD for flash media, are by far the most secure
and simplest to deploy, particularly for large organizations. Below
are some of key benefits of Addonics hardware encryption products:
- High performance - Data is encrypted
and decrypted on the fly by a certified cryptographic engine inside
an ASIC without taking any CPU resources
- Platform independency - There
is no software or driver to install to use Addonics encryption
products. As a result, it can be deployed in any system running
any OS. This is important in organization with multi-platform
computing and legacy systems.
- Data portability - Addonics encryption
storage device, designed with its USIB interface, can be used
as an internal removable hard drive or an external hard drive
connecting to USB, SATA, Firewire or CardBus/PCMCIA interface.
Unlike many software or hardware products that limit accessing
the encrypted hard drive to certain specified computer system,
Addonics encryption storage device can be accessed by practically
any system while still maintaining high level of security.
- No training required - There is
no password to remember nor running any special program commands.
The solution is truly plug and play. Encryption and decryption
is all controlled by a physical key.
- Low TCO (Total cost of ownership)
- With hardware based encryption, there is no IT mmanence required,
no software version to maintain nor any updates to keep track
of.
Bullet Proof security
The Addonics hardware encryption implementation offers
practically bullet proof security in comparing to software encryption
implementation. All Addonics encrytion solution are based on a certified Crypto engine from eNova. The latest Diamond Cipher is the first in the market that implement the AES-256 hardward encryption on SATA hard drive. Together with the implementation strategy in the Diamond Cipher enclosure, it is mathematically impossible to break the Cipher code.
Software encryption
It is well documented that a modern computer may
break software-based DES 40-bit encryption in a few days or in
a few hours if you can somehow manage to increase your computing
power. To break software based DES 64-bit encryption, the scale
of computing power you must gather with will dramatically exceed
your imagination. There are only specialized organizations capable
of managing supercomputers or thousands of personal computers
running in parallel that can discern the secrecy. Depending on
the level of actual investment, a few months or even years are
normally expected. Having stated that, breaking software DES 40/64-bit
requires special skills and expertise. It isn’t something that
regular Joe Smith can do efficiently.
Hardware encryption
It is extremely hard to break hardware-based
full disk encryption. The technique deployed to break software-based
encryption cannot be practically deployed to break hardware-based
encryption implemented in our design.
A hardware-based full disk encryption solution such as the Saturn or Jupiter Cipher
encrypts everything on the hard drive including boot sector, OS,
temp./swap files. There isn’t any clear text left on the hard drive
for trace, thus eliminates entirely the possibility of analyzing
useful patterns. Thus, traditional wisdom and techniques of breaking
software-based DES 40/64-bit is no longer applicable as no OS information
is available therefore no software application can be executed,
which greatly deters the process of key breaking as every wrong
attempt will require a new power on reset process of the hardware
or reconnection of the Addonics hardware encryption storage device..
So what’s so important about the power on reset and how does it
deter the key breaking process?
An Addonics hardware-based full disk encryption solution at
DES 40-bit strength offers a possible combination of 1,099,511,627,776
keys. The actual key will normally be yielded when the 50% of the
key domain is eliminated. A typical power on reset process lasts
0.4 second or more. The following simple calculation displays time
required in order to run through the 50% of the 40-bit possible
key domain:
1,099,511,627,776 x 50% x 0.4 seconds = 219,902,325,555 seconds
= 3,665,038,759 minutes = 61,083,979 hours = 2,545,165 days = 6,973
years
By increasing from DES 40 to DES 64-bit encryption, the possible
combination keys increase dramatically to 72,057,594,037,927,936.
When combined with the minimum 0.4 sec hardware reset,
the time required in order to run through
the 50% of the 64-bit possible key domain jumps up to 456,982,528
years! When applying this anaylysis to the TDE-192 and AES-256 bit encryption, the time it takes to find the right code combination will be so long that it is mathematically not possible to break these high bit level encryptions.
Or, a trained code breaker maybe able to directly connect to Addonics hardware-based full disk encryption hardware circuit
interface then attempt to intercept a complete data transfer for
deciphering, assuming known exact position of both clear text and
cipher text. Even if a potential hacker who has the clear text and
its corresponding cipher text, attempts to derive the cryptographic
key would still consume years as DES/TDES are known for resisting
“Known Answer Test.” A 40-bit hardware-based full disk encryption
solution specifically under the known answer attack is somewhat
weak but 64-bit solution will be a totally different scale.
Basing on the above analysis, we feel confident that the Addonics 64-bit products are more than adequate for most applications.
We do realize, however, there are rigid security requirements that
can not stand a chance from being compromised. In that case, we
shall recommend using the TDES 192-bit or AES-256 bit version.
