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.
2012-06-15Avoid 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.
2012-06-05Fix possible duplicate session establishmentMatthias Schiffer
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.
