2012-09-15Add support for kernel AES implementationsMatthias Schiffer
This gives AES128 a slight boost on my system, but it is still slower than XSalsa20... I should probably write userspace code that can make use of AES-NI and CLMUL. Or directly jump to the kernel space with the whole forwarding code. Nevertheless, this might run nicely on Geode CPUs and similar hardware with AES acceleration, at least if the context switches aren't too expensive...
2012-09-15Add support for using kernel implementations of GHASHMatthias Schiffer
This doesn't really improve performance on my Intel CPU (I guess due to the context switches), but more tests have to be made, in combination with offloading the AES to the kernel as well, and on different hardware.
2012-09-15Rework some parts of the AES128-GCM methodMatthias Schiffer
These changes improve the performance of the AES128-GCM method by ~10% on my Intel CPU when compiled with -O2. Furthermore, the AES and the GHASH parts are separated now, allowing to switch to other implementations of the algorithms more easily.
2012-09-14Critical: fix various problems in the AES128-GCM methodMatthias Schiffer
There were several bugs in the code that were severely lowering the expected security and completely breaking compatiblity with alternative implementations. The fixed version is checked against the test vectors specified in [1], and should thus be correct. [1] http://csrc.nist.gov/groups/ST/toolkit/BCM/documents/proposedmodes/gcm/gcm-revised-spec.pdf
