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

2012-06-15Version incrementv0.4-rc13Matthias Schiffer
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.

This is causing duplicate nonces in the worst case.

state can be used; remove the concept of temporary peers These changes will fix the possibility of a TCP-SYN-Flood-like DoS attack, at the cost of another protocol change: as we can't count request IDs when we don't know have temporary peers, request IDs are removed completely.
