RSA-576 Factorization Officially Announced

product byproduct writes "RSA Security finally has a news item about the December 2003 factorization of RSA-576. (See earlier Slashdot coverage). We now know what the computational cost was: the 174-digit number was factored "using approximately 100 workstations in a little more than three months"."

    Wow nice random word generator.. Can I have a go?

    Seriosuly, It's utter rubbish. I mean please explain to me how you stack an S-box into a corner of a cryptographic chamber..

    It's just a substitution you muppet.. And cryptography isn't all hardware speed.. I mean WEP

    was broken with trivial computing power!

    Simon.

    Bear in mind, using bits to exponentially increase cryptographic strength only works until you reach the Berenstein factor, which is a practical limit on the number of S-boxes that can be stacked in any particular corner of the cryptographic chamber. After a certain point, which varies according to the chamber ceiling, it is possible albiet less space efficient to take advantage of parallel stacking to some extent.

    Mods -- how could you let this get modded up? First, S-boxes are in DES, not RSA. Next, even if the random reference was to the correct cryptographic algorithm, the rest of the comment still makes no sense at all.

    C'mon people, post if you have a clue, and only if you have a clue.
