Q: Has a change taken place in factoring RSA keys?
by Jim Choate 29 Oct '03

29 Oct '03

Hi, One of the local Linux user groups had a talk at their meeting as well as some extended discussion on the mailing list regarding RSA keys and factoring. In particular a claim was made that recent technology has come to light that allows factoring of 1024 bit RSA keys at $1B (US)/day. The basic gist was that they were claiming that 1024 keys were no longer reasonable outside of a life time of approx. a year. That 2048 keys were by extension weaker, and that larger keys should be the norm. There was some discussion about hacking GPG to generate 8k keys. I'm wondering if anyone might comment on this with regard to sources of info or other efforts? In particular I'm interested in any leads regarding this supposed hardware breakthrough. I spent about an hour googling around and didn't really come up with anything substantial. Thanks. -- -- Open Forge, LLC 24/365 Onsite Support for PCs, Networks, & Game Consoles 512-695-4126 (Austin, Tx.) help(a)open-forge.com irc.open-forge.com Hangar 18 Open Source Distributed Computing Using Plan 9 & Linux 512-451-7087 http://open-forge.org/hangar18 irc.open-forge.org James Choate 512-451-7087 ravage(a)ssz.com jchoate(a)open-forge.com

I'd It's not setting up tls itself that's the problem, really, it's the cert generation that got me bogged down and so everytime I've tried it, first with sendmail and then with postfix, I've ended up with "okay, when I've got more time I'll finish this". Of course, ipsec is the same way. Setting up ipsec on a cisco router is sure a lot easier. -- Harmon Seaver CyberShamanix http://www.cybershamanix.com

Tim May wrote... "But silliness about "if everybody used encryption, then..." is just that, silliness." You seem to miss my point here (and in general), and since this is probably the closest area in which we agree, I'd suggest it's worthwhile examining this. Let's first of all agree that the proliferation of crypto is a good thing. If crypto is rarely used, then MY usage of it is actually almost worse (depending on context) than using it. More than that, increased use of crypto implies increased cost of monitoring. The $$$ nature of the assymmetry is mirrored precisely by the calculational assymetry. Ideally, it seems to me that this should be exploited. "If only everyone" is I agree largely pointless in and of itself. However, when coupled to some fairly easy and obvious applications of "greed", the potential results are interesting. Want an example? We now see file trading, messaging, and possibly even IP telephony occuring in P2P networks. Some of the P2Ps will be/are encrypted...a primitive form of "blacknet" you might say. Couple this app with popular notions of "protecting us from the terrorists" and you may have wildfire. That's the goal: wildfire. You're problem is that you don't realize that crypto is no longer a technological issue now. It's now a social and marketing one. The fact that "Tyler Durden" actually has little of major insight to say completely misses the point. Ideally, "Tyler Durden" is a generic, popular figure that embodies virulent, 'stoopid' popularity. Tyler Durden is not an intellectual: He's basically a dumb punk and a rabblerouser. Ideally, he's every man. He's everything you've always been afraid of, but he is precisely the one who can set you free. -TD >From: Tim May <timcmay(a)got.net> >To: cypherpunks(a)lne.com >Subject: Re: "If you DON'T use encryption, you help the terrorists win" >Date: Mon, 27 Oct 2003 18:40:51 -0800 > >On Monday, October 27, 2003, at 08:50 AM, Tyler Durden wrote: > >>"Basically they say things like "If you think the government can't break >>all >>the encryption schemes that we have, you're nuts."

"Dave Howe" <DaveHowe(a)gmx.co.uk> writes: >I was under the impression they had just licenced their *patent* Yup, and that's all they did. I've seen some downright bizarre interpretations of this particular portent on the web (<cough> slashdot</cough>), but the simple fact is that the NSA, in its role as the agency responsible for overseeing crypto use by the USG, got a blanket Certicom patent license for cases where ECC (of the Certicom-patented variety) is used, just as they got a blanket DSA license for DSA, and would have had to get a blanket RSA license before that if it hadn't been USG-funded work and a blanket DES license if IBM hadn't made the patent freely usable. Certicom's PR folks, seeing an opportunity, put out a press release saying that the NSA had licensed their patent(s). This does not mean that the NSA is about the drop their own crypto for ECC (definitely the silliest interpretation of Certicom's press release I've seen), nor is it a sign that they believe RSA is dead or that the end of the world is nigh, etc etc etc. Peter.

Tim May wrote... "I predict we'll soon be seeing a new thought control campaign with this theme, that "if you use encryption, you help the terrorists win."" Well, I'm dubious. Right now I'm thinking their strategy has been to pull encryption down off of the social radar, and that's worked better than any frontol assault. Also watch carefully for hole-pokers...I'd bet their's also been disinfo campaigns to get the public to think that no crypto is secure (every ask anyone if they believed there was such a thing as effectively 'unbreakable' encryption? Reglar folks always believe SOMEBODY'S got the technology to break what scheme you use, so "why bother"). Let's also remember that 'terrorists' are only terrorists when their guns are small. Once they start winning a few battles they're no longer "terrorists" (eg: Mao and that whole gang). So let's beat them to the punch: "Use strong crypto in order to keep America free from the terrorists." -TD >From: Tim May <timcmay(a)got.net> >To: cypherpunks(a)lne.com >Subject: "If you use encryption, you help the terrorists win" >Date: Fri, 24 Oct 2003 14:52:02 -0700 > >I predict we'll soon be seeing a new thought control campaign with this >theme, that "if you use encryption, you help the terrorists win." > >Similar to the heavy advertising (paid for by Big Brother, and hence by >money stolen from taxpayers) with the theme that lighting up a doobie helps >Osama, that taking an Oxycontin (sorry, Rush!) is equivalent to flying a >plane into the World Trade Center. > >Why encryption?

"If you DON'T use encryption, you help the terrorists win"
by Tyler Durden 27 Oct '03

"Basically they say things like "If you think the government can't break all the encryption schemes that we have, you're nuts." This guy was a math major too, so he understands the principles of crypto." Basically, the answer was hinted at by another poster. For anyone who doesn't trust the government, the point to make is that crypto use is currently a red flag. Last year I went through great pains on this list to point out that right now the gubmint probably doesn't even need to break most encrypted messages in order to know something's up. This is only possible because outside of a coporate context few individuals use encryption. If everybody uses encryption, then it matters MUCH less if the government can break any one message. What costs us pennies to encrypt may cost them thousands to break. That's the assymmetry we asyms can exploit. That's where we need to depart from a Tim May lone wolf approach to your friendly, smiling America-loving flag-waving cypherpunks: "If you don't use encryption then you help the terrorists win". This statement has the added irony of being objectively true, according to more international definitions of 'terrorism'. -TD >From: Burning Cows with Strauss <steve(a)njord.org>(by way of Burning Cows >with Strauss <steve(a)njord.org>) >To: cypherpunks(a)lne.com >Subject: Re: "If you use encryption, you help the terrorists win" >Date: Sun, 26 Oct 2003 20:37:47 -0600 > >-----BEGIN PGP SIGNED MESSAGE----- >Hash: SHA1 > >On Saturday 25 October 2003 04:27 pm, Tyler Durden wrote: > > Tim May wrote... > > > > secure (every ask anyone if they believed there was such a thing as > > effectively 'unbreakable' encryption?
