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
CBC – Cipher Block Chaining
-
Feeds forward encrypted data to produce a stronger
cipher-text result than ECB
-
Fully NIST / FIPS140-2 approved algorithm
XTS – XEX-based Tweaked CodeBook with CipherText
Stealing
-
Variant of AES developed for protecting data at rest,
also known as IEEE P1619
