Description:
|
|
|
|
This optimised implementation of Rijndael is noticeably faster than the
|
|
previous versions on Intel processors under Win32 w/ MSVC 6.0. On the
|
|
same processor under Linux w/ gcc-2.95.2, the key setup is also
|
|
considerably faster, but normal encryption/decryption is only marginally
|
|
faster.
|
|
|
|
To enable full loop unrolling for encryption/decryption, define the
|
|
conditional compilation directive FULL_UNROLL. This may help increase
|
|
performance or not, depending on the platform.
|
|
|
|
To compute the intermediate value tests, define the conditional
|
|
compilation directive INTERMEDIATE_VALUE_KAT. It may be worthwhile to
|
|
define the TRACE_KAT_MCT directive too, which provides useful progress
|
|
information during the generation of the KAT and MCT sets.

N.B. Both the API implementation and the provisional reduced set of
|
|
test vectors are likely to change, according to NIST's final decision
|
|
regarding modes of operation and the FIPS contents. They are therefore
|
|
marked as "version 2.9" rather than "version 3.0".
