Encryption

Development Support

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

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
