The DEU operates by permuting 64-bit data blocks with a shared 56-bit key and an initialization vector
(IV). The SEC supports four modes of operation:
For more information about the unit’s operation, refer to
Execution Unit (DEU).”
10.1.4.3
The AESU is used to accelerate bulk data encryption/decryption in compliance with the Advanced
Encryption Standard algorithm Rijndael specified by NIST standard FIPS-197. The AESU executes on
128 bit blocks with a choice of key sizes: 128, 192, or 256 bits.
AES is a symmetric key algorithm, meaning the sender and receiver use the same key for encryption and
decryption. The session key and IV are supplied to the AESU module prior to encryption. The processor
supplies data to the module that is processed as 128 bit input.
AESU implements the following confidentiality modes from NIST Recommendation 800-38A:
AESU also implements other NIST recommended modes providing authentication (two of which also
provide confidentiality):
AESU modes also implement the following modes not sanctioned by NIST:
In all modes supporting authentication, the AESU hashes data to produce an integrity check vector (ICV).
If a reference ICV is supplied to the AESU, it can do a bitwise check of the reference ICV against the one
computed by the AESU.

Execution Unit (AESU).”
