Subject: Format of rc5 files
We've a bunch of FPGAs in PCI cards we're interested in
enlisting in the RC5-64 effort. Do you guys have any support for this
kind of thing?
Ideally, we would like some way of getting rc5desg to spwan a
sub-process, which it dispatches key blocks to to (e.g., an input pipe
with key blocks and config, and an output pipe with progress and
I realise you guys have a problem with authenticating key blocks which
have been processed with code other than your own. It is possible that
that part of the results we generate are a hash value of all the A & B
registers after we've encypted the plain text? That way the rc5des
program could selectively validate key blocks we've processed.
We're not expecting a huge amount of grunt. It we got machines for all
of the FPGAs currently spare going we could do maybe 14Mkeys/s (peak).
Anyway, I'm sure you're probably been through this before.
