I think their point was this:
When using a Pico FPGA cluster, however, each FPGA is able
to perform 1.6 billion DES operations per second. A cluster
of 176 FPGAs, installed into a single server using standard
PCI Express slots, is capable of processing more than 280
billion DES operations per second. This means that a key
recovery that would take years to perform on a PC, even
with GPU acceleration, could be accomplished in less than
three days on the FPGA cluster.
So, they managed to brute-force DES a lot faster. No crypto breakthrough, please move along. :)
This should have been titled "FPGA cluster brute-forces DES in record time" or something like that.
- patrickgzill 17y agoClearly the NSA has had such capabilities for a long, long time now.
- redmage 17y agoSure, but I suppose their means didn't consist in a PCI Express card filled with FPGAs, like described in the article.
- cperciva 17y agoFPGA cluster brute-forces DES in record time Even that isn't true. Deep Crack took 56 hours (matching the "less than three days" claimed in the article), while the combined Deep Crack + Distributed.Net effort took less than 24 hours.
- redmage 17y agoSorry, my bad. I didn't bother to research, just pulled that from the article. Pico Computing has announced that it has achieved the highest-known benchmark speeds for 56-bit DES decryption, with reported throughput of over 280 billion keys per second achieved using a single, hardware-accelerated server.
- cperciva 17y agoOk, so 12 years after Deep Crack they've managed to get triple its performance. I can't say that I'm very impressed.
- redmage 17y agoWhat can I say? Pico Computing likes to brag and Dr. Dobb's published an article about it. As you said in your first comment, there's nothing new about this.
- sp332 17y agoDeep Crack used specialized ASICs. The breakthrough is that these general-purpose (reprogrammable) FPGAs are actually faster.
