This patch enables support for quantum cryptography on latest b43 devices.
The quantum cryptography algorithm is 100% backward compatible with the
standard CCMP algorithm, so no additional changes to the mac80211 stack
are needed. While staying compatible, it makes the unbreakable(!) WLAN connection
possible. Of course, that's only the case, if both ends use b43-qcrypto.
In the case where one STA uses legacy encryption, the card will automatically
detect this and switch back to plain old CCMP.

Excellent, did you manage to implement the time travel support mode as
well?

Most likely not, that only works on Ralink hardware, and rt2x00 will
support that with the 2.2.0 release.

Sure. I used it to actually get one of those q-crypto devices to test
the code. ;)

I tried this patch against the 3.6 tree and I was unable to get it to
compile.
It kept saying my version of gcc is too old.
Is it my SPROM?
Ehud

Try the latest GCC 6 development version, that should work. (I tested
it on a Core 4 Hexadeca CPU, not sure if it will work on Core 3 Octos,
as it seems to use SSE6 instructions. Maybe DDR5 RAM is required,
too.)
