OXUF943SE, FireWire 800 or USB 2.0 to SATA Controller with Encryption
Encryption
The integrated hardware cipher engine supports real-time, on-
the-fly encryption / decryption of the data to the Advanced
Encryption Standard (AES), providing a means whereby a users’
data can be securely stored, and made unavailable to
unauthorized users.
The cipher engine can be configured for the following AES
algorithms:
o ECB – Electronic Code Book
- Simplest implementation of the AES algorithm
- Fully NIST / FIPS140-2 approved algorithm
o CBC – Cipher Block Chaining
- Feeds forward encrypted data to produce a stronger
cipher-text result than ECB
- Fully NIST / FIPS140-2 approved algorithm
o XTS – XEX-based Tweaked CodeBook with CipherText
Stealing
- Variant of AES developed for protecting data at rest,
also known as IEEE P1619
In addition to a high-performance cipher engine, the
OXUF943SE is complemented by robust authentication
solutions, including software password. A customizable host
application, the PLX Technology Authenticator, is provided for
both PCs and Mac hosts to:
o Define and manage up to 10 passwords
o Authenticate and mount the drive
o Safely de-authenticate and un-mount the drive
Development Support
For external Mac and PC storage solutions, PLX Technology
offers a comprehensive support package including:
o Reference designs comprising both hardware and software
components
o Evaluation boards with pre-built application firmware
o Software Development Kit (SDK) comprising source code
and debug boards
o Extensive range of application notes to shorten learning
curves and simplify implementation
