If you look back at Dr Chris Monico's work at cracking ECC-109 you can get some more background on the equivalences and how they match up and how the two are compared and how they are very different. 109 took a lot of computational time (biggest ever so far I believe), and this is vastly bigger, as if I remember correctly ECC encryption doesn't grow linearly, but exponentially. The code used to crack ECC-109 has been somewhat improved in ECC2-109 based mainly on things Dr Monico saw in 109 and based on some research he and I did regarding a paper by Teske of Waterloo.
Hope that is informative.

I expected this reponse, of course, but you are missing something..like the point of the site. If the Net and the Web can be used to communicate content like books apart from entities like big publishes, big media (big software manufacturers), that's very newsworthy. I want other people who create content to understand how this could work.So I think you are missing something. There are many better venues to promote a dog book than on Slashdot, but I really feel strongly that writers, artists, individuals, etc. should understand that mailing lists, blogs, etc. are a huge opportunity to bypass the big company/big media marketing systems. To me, that's a big OS idea, the reason I came to write for the site in the first. It's essential that this message get out, I think,as so many music writers, book writers, etc., are not able to deal with big marketing realities.
