AES cipher algorithms (FIPS-197). AES uses the Rijndael
|
|
algorithm.
|
|
|
|
Rijndael appears to be consistently a very good performer in
|
|
both hardware and software across a wide range of computing
|
|
environments regardless of its use in feedback or non-feedback
|
|
modes. Its key setup time is excellent, and its key agility is
|
|
good. Rijndael's very low memory requirements make it very well
|
|
suited for restricted-space environments, in which it also
|
|
demonstrates excellent performance. Rijndael's operations are
|
|
among the easiest to defend against power and timing attacks.
|
|
|
|
The AES specifies three key sizes: 128, 192 and 256 bits
|
|
|
|
See <http://csrc.nist.gov/encryption/aes/> for more information.
|
|
|
|
In addition to AES cipher algorithm support, the acceleration
|
|
for some popular block cipher mode is supported too, including
|
|
ECB, CBC, LRW, PCBC, XTS. The 64 bit version has additional
|
|
acceleration for CTR.
