I got the following forwarded along yesterday from someone who'd had it forwarded along, apparently with reasonable permission along the chain. The message indicated the paper could be distributed, so I don't think I'm violating any trusts.
Unfortunately the attached paper (which I'm still reading) is far too long to email to the whole list, but I'm trying to get a URL for it so people can download it at will. ---------------------------------------------------------------------- [...] From: Adi Shamir[...] I am attaching to this email a new paper coauthored with Eran Tromer. It describes a new hardware device called TWIRL (The Weizmann Institute Relation Locator) which is 3-4 orders of magnitude more efficient than previous designs (including TWINKLE) in implementing the sieving part of the NFS factoring algorithm. Based on a detailed design and simulation (but without an actual implementation), we believe that the NFS sieving step for 1024-bit RSA keys can be completed in less than a year on a $10M TWIRL machine, and that the NFS sieving step for 512-bit RSA keys can be completed in less than 10 minutes on a $10K TWIRL machine. Please feel free to send copies of the paper to anyone you wish. Best regards, Adi Shamir.
