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.
2012-09-15Improve data alignmentMatthias Schiffer
Ensure that the actual packet data is always aligned to a multiple of 8.
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

2012-06-15Avoid using the same handshake key to establish more than one sessionMatthias Schiffer
This fix prevents a potential attack using intentional packet reordering to initialize more than one session with using the same handshake keys, leading to more that one session to be initialized with the same key data altogether, allowing to decrypt some packets in the worst case.
