  3. 12-year old technology, today! by Anonymous Coward · · Score: 0 · on Parallel Algorithm Leads To Crypto Breakthrough

    The EFF DES cracker from 1998 could crack DES in 2 and a half days. Now, 12 years later, they've just equalled that performance?

    OK, the people in TFA used 176 FPGAs rather than 1856 ASICs, which is presumably slightly cheaper.

    So perhaps a better comparison would be the FPGA-based COPACOBANA codebreaker, which used FPGAs and took a week to break DES back in 2006.

    This is not a "breakthrough", it isn't even novel.

    (By the way, that EFF DES cracker page was the first result on a web search for "des cracker", it's not exactly hard to find).

  4. Breakthrough? meh. by gmarsh · · Score: 2, Informative · on Parallel Algorithm Leads To Crypto Breakthrough

    Brute-forcing DES doesn't require any creative algorithm to be run in parallel. You have 2^56 possible keys, split them amongst 2^n crackers and each cracker has to process 2^(56-n) keys. Not too hard.

    And loading an array of DES cracker cores onto an array of chips isn't novel either, ie:

    9 days is a pretty old figure. It's still more than 2 minutes, but it's not very long if you're willing to buy the hardware:

    For $10,000 in hardware you can crack 56 bit keys in less then a week. Soon it will be 3 days for equivalent money.
    56 bit crypto is dead, dead, dead.
    See http://www.copacobana.org/ for one such project.

    or 100's of FPGA's can do what was previously considered a task that even with super computing resources was considered so time consuming to be only worthwhile for groups like the nsa: http://www.copacobana.org/index.html (the EFF had a simlar custom chip device several years before but that cost >$250K)

    Why use FPGAs when you could go custom:

    This can brute-force a 56-bit DES key in a matter of days. This was built by the EFF for $250,000, so we can safely assume that the vastly better funded NSA can do the same or better.

    It get's better: http://www.copacobana.org/
    This costs less than $10,000 and takes no longer than a week on average to brute-force a DES key. It is not limited to DES, and can attack any symmetric cipher up to roughly 64 key bits. Examples include CSA (Common Scrambling Algorithm) or GSM A5.

    January 13, 2006: Improved code reduces brute-force attack against DES to 7 days

    Our new DES design can now be clocked at 120MHz. This reduces the average search time of the DES key space to 7.2 days. The worst case for a brute-force attack is now 14.4 days.
