Likely a combination of both. :-) Here is is anyway: Subject: Help break RSA's DES Crypto Challenge! A Call for Participation ------------------------ 1) What's it all about? We're working on breaking the DES challenge issued by RSA Labs on Janurary 28th, 1997. Two of the other challenges, based on the RC5 algorithm with 40 and 48 bit keys, have already been broken. Especially in the 48bit RC5 challenge, a large number of Internet users contributed CPU cycles for a brute force keyspace attack. By the end of the 48 bit RC5 challenge, over 3500 hosts had helped by donating CPU time to acheive a peak key-testing rate of over 1.5 trilion keys/hour. We'd like for some of those hosts (and others!) to help out with the DES challenge. A $10,000 prize will be awarded by RSA Labs for those who crack the challenges first. 2) How can I help? First, feel free to redistribute this CFP to anyone else who you think may be interested in participating. Especially those with alot of CPU power. :-) If you've got a networked computer somewhere, you can help directly! Clients are currently available for Intel processors (486, Pentium, and PentiumPro) running Windows, OS/2, Linux, FreeBSD, and BSDI. Non-Intel clients are available for PowerPC (Mac) Linux, Sun Sparc, and HP PA-RISC. The Intel versions are all using hand-optimized assembly code. Assembly tuned versions for the Sparc and PA-RISC versions should be available in the near future -- stay tuned! The only restriction is that clients can only be given to residents of the US or Canada, due to US export restrictions. [Others may still be able to participate; rumor has it that someone has redistributed the clients outside the US, but I don't know the location.] To get the clients, visit the DESCHALL Info page (see below) for instructions. It's simple and painless process. You just need to download and execute the clients -- no further work on your part is required! You can visit the statistics page to see the progress of the whole group, and your clients. If you have a multiple number of Unix systems you'd like to use, I've written a few scripts to help make life simple (read: automated). Contact me directly for further info. 3) Where can I get more info? * DESCHALL Info page: * RSA Lab's Challenge: * Rocke Verser (coordinator/implementor): rcv@dopey.verser.frii.com Justin Dolske (dolske@cis.ohio-state.edu) Graduate Fellow / Research Associate at The Ohio State University, CIS Dept. -=-=-=-=-=-=-=-=-=-=-=-=-=- Random Sig-o-Matic (tm) -=-=-=-=-=-=-=-=-=-=-=-=- (This space intentionally left blank.)

This is pretty impressive considering that these are just individual owned computers; the head honchos of our computer labs seem to have decreed that deschall shall not be run on school computers... If some sort of inter-school rivalry could be setup, I think a lot more people would be willing to take part. This would be especially true at places like MIT, RPI, RIT, WPI, and other techie schools, where there are enough dedicated computer scientists who would care about such things, and coincidentally enough, tend to have powerful computers to crack considerable numbers of codes...

So please don't consider these suggestions with any more weight than any others. Paragraph 2. How about "insufficient" in lieu of "minimal" General: How about some mention of the US Government's 40-bit limit on cryptographic export without special licensing. For example: "The maximum key-length allowed for export by the US Government without special licensing is 40 bits. If every Fortune 500 company used a single 40-bit key to communicate with their international offices and subsidiaries, the meager computing power expended as of March 31 by the DESCHALL group could have revealed approximately half of their keys. At the present pace, approximately twenty-two additional secrets could be compromised each day." Note: This is based on DESCHALL clients having tested 0.2% of 2^56 keys (1.44e14 keys); Keys required to find average 40-bit key is 2^39 = 5.5e11; 1.44e14 / 5.5e11 = 262. Second statement is based on 1.24e13 keys per day; 1.24e13 / 5.5e11 = 22.6 secrets compromised per day. General: How about a mention of a DES application that would concern the average citizen. Is single DES still used between banks and the Federal Reserve? Do Visa and MasterCard still use single DES? Other applications that could impact the average American? -- Rocke From owner-deschall Wed Apr 2 11:38:20 1997 Received: (from majordom@localhost) by gatekeeper.megasoft.com (8.7.5/8.7.3) id LAA26599 for deschall-outgoing; Wed, 2 Apr 1997 11:38:20 -0500 (EST) Received: (from uucp@localhost) by gatekeeper.megasoft.com (8.7.5/8.7.3) id LAA26591 for ; Wed, 2 Apr 1997 11:38:19 -0500 (EST) Received: from lucifer.testlab.orst.edu(128.193.78.11) by gatekeeper.megasoft.com via smap (V2.0) id xma026587; Wed, 2 Apr 97 11:37:58 -0500 Received: by lucifer.TestLab.ORST.EDU with Internet Mail Service (5.0.1457.3) id <2BAY9T09>; Wed, 2 Apr 1997 08:47:34 -0800 Message-ID: <71846B925036CF11BD6D00C0D157092910132D@lucifer.TestLab.ORST.EDU> From: Adam Haberlach To: deschall@gatekeeper.megasoft.com Subject: RE: Recruiting More People; .EDU sites (rambles) Date: Wed, 2 Apr 1997 08:47:31 -0800 X-Priority: 3 X-Mailer: Internet Mail Service (5.0.1457.3) Sender: owner-deschall@gatekeeper.megasoft.com Precedence: bulk Carleton = Carleton Jillson > Carleton> First off, let's look at the top ten contributors: #4 is > 207.196, which I > Carleton>have no idea what it is, except judging by the amount it puts > forth with > Carleton>just one computer, must be 1 hell of a computer..., #10 is > ibm.net, which > > We have been trying to figure that out as well--can we tell if they > have more then one proc or which client they're running?

I have a few comments on "Recruiting More People". 1. As for the .EDU domains, probably the easiest machines you may have access to are all the computers in the dorms. These days the students at many universities have ethernet in the dorm rooms and don't pay monthly electrical bills. If you can contact those students, I feel the number of machines would greatly increase. Besides "Crack DES" has a hacker spirit to it that most college students would be willing to join. Yes, the computer labs are the best places since there are so many machines and an administrator, but I can sympathize with the sys admin. One stupid program playing with any of the system configurations could cost them dearly. (I'm not saying DESCHAL is such a program. Just try to understand the sys admins position.) The press release should help in all our recruiting. 2. As for .COM domains... I think we could get some corporate support from the computer manufacturers if we present the benefits for finding the key. If the key were found on say a Compaq machine, Compaq could claim that their new workstations are fast. (This is not to say that I am supporting the claim.) Breaking DES on a machine could give the manufacturer a few nice press releases about how well their machines work and are constructed. I know Cray/SGI put out press releases on the last largest prime number they discovered. Although the largest prime discovered to date was not on a Cray, it still looks nice that Cray can claim to have discovered several of the largest prime numbers. By the way this can also work for the universities...

FWIW, it's interesting that the client that found the key for the 48bit RC5 client wasn't in the top 10. It was like 30th on the list by top domains. On another note, have any .edu users figured out what to do with the $$$ if you win? After all, we're using school resources, and most (all?) schools have rules about using systems for personal profit. I havn't dealt with the issue yet, but I'd probably just be donating it to EFF or someone similar. > > We are currently waiting for word from some of the Engineering > > profs for a blessing to set the HP-PA client up on around 200 HP 7xx > > machines run by the department.

Well, this isn't actually the first successful DES crack. [Even if you discount the virtual certainty that the NSA does it all the time. :)] At least one chosen-plaintext attack has been done as a demonstration (took about 4 days with 30 workstations). This is a little different than a brute force attack, though...

If you are talking about exporting the client portion of deschall to get worldwide participation. a) I've heard that it has already been pirated abroad. b) As I said on cypherpunks some time back, it is arguable whether the deschall client is "encryption software". It doesn't allow anybody to encrypt their data files or communication lines. The correct thing to do is to ask the BXA for a commodity jurisdiction advisory to clarify whether the deschall client needs a license to export. How to apply for a CJ is detailed in the EAR. c) It is obvious, at least to me, that the deschall client is a research tool and not commercial software. As such the EAR doesn't prohibit providing the source code to somebody in Europe in paper form. If Rocke is willing to do this with an European reasearch associate, under a non-disclosure agreement, it is again advisable to get a commodity jurisdiction decision from the BXA first.

Two silly questions though, where would the ID numbers be stored, on the client end, or the server end? If it's stored at the server end, what happens if there are two many ID's assigned? And how do the machines generate their first individual ID, some kind of time-date-stamp? My second question is, if you have ID's, you might want to set some variable, tied to a particular ID with an identification of some sort.

Just for kicks, and go possibly give people a sense of scale: Assuming a single piece of hay (straw? :) is a 10cm long, .2 cm wide cylinder, and they're all packed fairly tightly together... V_haystack = (2**56) * 10cm * pi * .01cm = (2**56) * .311415926 = 22,637,560,806,492,498 cm^3 given that V_sphere = 4/3 * pi * r**3... [haystacks are not spheres, but we'll assume it's a half-sphere by doubling the volume] r_haystack = 2.21km = 1.37 miles So, we're looking for a needle in a haystack over 2.5 miles wide, 1 mile high. :-) Hmm. Given that I've done about 5% of the .2% we've searched (I think), I've searched through a haystack about 230 yards wide, 115 yards high. *looks out the window towards OSU's football stadium* Yikes! That's big! Hmm. So a client searching 100,000 keys/sec is searching through a cube of hay about 1 foot/side every second.

The avergage change in growth was 1.12658, if we can keep this rate up it will take 84 days more to complete the entire space. Say interest flags a little, or the market gets a bit more saturated and we drop to an average growth rate of 1.1 it will take 105 days more to complete the entire space. Say, with the press realease and all going out, that interest picks up such that we get an average growth rate of 1.13, then it will take 82 days to complete the enitre keyspace. All of these require about 5000 times the current effort. We currently have about 900 machines participating where we will have 4.5 million machines by the end.

It might be a udp proxy handling a number of machines. Or would a Quad PPro 200 be around that rate? Karl BTW, I written some perl scripts to redirect udp traffic on my two (pitifully slow) machine home LAN to the keyserver (udp traffic on my slip link is flakey). It's been working well for 5 days now (Well, Rocke hasn't complained that I'm messing up the server). If any body has a situation where they think they may benefit from something like this just drop me a line. ---------------------------------------------------------------------------- Karl J.

Sure, let me add a comment or two after work and I'll get them to you in a few hours. I'll detail some of the things I've done for my setup and we can decide what, if anything, is transferable to client runners in the large. Karl PS.

For some reason the 586-133 linux box here is processing keys at a rate closer to my 486dx2-66 linux box than my P90 OS/2 computer (and the P90 does about twice as many keys as the 486). Are there any plans on releasing intel clone editions of deschall (I'm upgrading to a 686-P200 clone soon), as it seems strange that the 586 clone should be so much slower than the P90. I'm running Deschall on an IBM (Cyrix) 686-133mhz, it performs slower then on an Intel Pentium 120mhz. Though normally this chip will outrun an Intel 166mhz Pentium except in FPU, and Deschall uses 100% integer. I think the problem comes from the fact that Deschall is optimized for the Intel Pentium and the non-Intel chips use a different internal architecture making the optimizations different. I've noticed in my case the deschal4 (486) and deschal5 (Pentium) both run at the same rate.

Cray's Web page indicates that the T3E-900 is scalable to "thousands" of processors. They say each processor does around 900mf, so a 2000 processor system seems to be the system that's doing 1.8tf.

Your numbers are hence off by a factor of 100. I believe, with properly optimized software (that I don't have now), the 450 MHz Alpha at the heart of the T3E-900 can test on the order of 5 million keys a second. For a fully configured system, that is 10 billion keys per second, or three months for the entire key space. If all one really wanted was to break DES, designing and manufacturing custom hardware works out much cheaper, and you can break a key within minutes rather than months. > > 1 Cray T3E-900 hunting > 600,000*1,800,000=1080000000000 keys per second will hunt the entire keyspace > in 18 hours. > > The MIPS vs FLOPS thing could be off by up to 2 orders of magnitude, but, at it's > worst, the cray can crack DES in 1800 hours= 75 days Your "2 orders of magnitude" corrects for the factor of 100 error above and comes up with an estimate not much different from mine. -- Anil Das From owner-deschall Sat Apr 5 10:41:33 1997 Received: (from majordom@localhost) by gatekeeper.megasoft.com (8.7.5/8.7.3) id KAA16778 for deschall-outgoing; Sat, 5 Apr 1997 10:41:33 -0500 (EST) Received: (from uucp@localhost) by gatekeeper.megasoft.com (8.7.5/8.7.3) id KAA16773 for ; Sat, 5 Apr 1997 10:41:32 -0500 (EST) Received: from kelly.iaonline.com(206.68.129.7) by gatekeeper.megasoft.com via smap (V2.0) id xma016771; Sat, 5 Apr 97 10:41:28 -0500 Received: from dialup25.iaonline.com (dialup25.iaonline.com [206.68.128.203]) by kelly.iaonline.com (8.6.12/8.6.9) with SMTP id JAA12260 for ; Sat, 5 Apr 1997 09:54:36 -0600 Received: by dialup25.iaonline.com with Microsoft Mail id <01BC41A6.760D7020@dialup25.iaonline.com>; Sat, 5 Apr 1997 09:48:06 -0600 Message-ID: <01BC41A6.760D7020@dialup25.iaonline.com> From: "Michael R.

You can kill the client at any time. Whatever block it was working on will be reassigned to you or to another client. Killing the client soon after a new keyspace begins means few wasted cycles on your machine. To elaborate on a previous response you received... Currently, unreturned keyspaces expire and are reassigned when I rotate the logs. I have been rotating the logs about 2 hours after midnight, and expiring all unreturned keys issued during the previous midnight-to-midnight period. The shortest time before a key expires is thus about 2 hours. The longest time is about 26 hours. As the load on the server increases, I will probably start rotating the logs more than once per day, and I will try to get a more uniform sliding timeout period of (say) 6 hours. -- Rocke From owner-deschall Sun Apr 6 05:30:55 1997 Received: (from majordom@localhost) by gatekeeper.megasoft.com (8.7.5/8.7.3) id FAA18724 for deschall-outgoing; Sun, 6 Apr 1997 05:30:55 -0400 (EDT) Received: (from uucp@localhost) by gatekeeper.megasoft.com (8.7.5/8.7.3) id FAA18719 for ; Sun, 6 Apr 1997 05:30:54 -0400 (EDT) Received: from relay4.oleane.net(194.2.1.6) by gatekeeper.megasoft.com via smap (V2.0) id xma018717; Sun, 6 Apr 97 05:30:36 -0400 Received: from joel (joel.apsydev.com [194.3.103.40]) by relay4.oleane.net with ESMTP id LAA31999 for ; Sun, 6 Apr 1997 11:39:02 +0200 (MET DST) Message-Id: <199704060939.LAA31999@relay4.oleane.net> From: "Joel Armengaud" To: Subject: UDP Procotol Date: Sun, 6 Apr 1997 11:35:42 +0100 X-MSMail-Priority: Normal X-Priority: 3 X-Mailer: Microsoft Internet Mail 4.70.1160 MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Sender: owner-deschall@gatekeeper.megasoft.com Precedence: bulk Could someone explain the numbers in the UDP protocol used between the client and the server?

Now, those of us cursed with limited usage dial up accounts have an answer! I found a program, freeDUM103.zip that will allow one to schedule automated connection/disconnections to your ISP. I setup freeDUM to dial in at 5 and at 35 minutes past the hour on my Pentium 133. A 2*2^29 key search takes about 1650 to 1750 seconds (depending on what I'm doing) so dialing in every half hour makes sense. The dial in times are adjustable and easy to use. I just found it a couple of hours ago, so I don't know for sure all the implications/limitations/bugs/features of this program, but it sure is what I was looking for. The program can be found at: http://homepages.ihug.
