I hope I will have more echoes using the hardware mailing list.

I'm Guerric Meurice de Dormale and I'm a Ph.D. Student at the
UCL CryptoGroup (Belgium) under the supervision of Jean-Jacques
One of our Ms.C. Student is currently finishing the implementation the
RC5 32/12/9 challenge on an FPGA platform. It is a fully pipelined design
with a throughput of one key search every clock cycle.
Currently, the engine should goes up to 150M keys/sec on a Xilinx
VirtexII6000-5 device. In the future, it is planned to use Virtex4LX
FPGAs with a higher logic density and a higher maximum operating
frequency (a twofold improvement about the frequency is expected (?)).

It could be very valuable for the work of our student to join the
distributed.net cracking effort. However, as the communication
protocol is not available, it is not possible without your support.
Nevertheless, it seems that people were planning to enable FPGA engine
within the key search effort (cfr. Hardware mailing list). Does
someone know if something was done in that area? or if something could be

I already thank you for reading this email.
I hope we could join distributed.net soon!
