Cc: runge@crl.com From: runge@crl.com (Karl J. Runge) Sender: owner-deschall@gatekeeper.megasoft.com Precedence: bulk Hi, I'm new to this list (forgive me if I put my foot in my mouth!) I have downloaded deschall for linux and would like to run it on my PC, however I have a problem. I have a 24hour/day connection to the net, but through a slip emulator. Unfortunately the UDP traffic with my emulator is pretty buggy, and would prefer to use TCP somehow. Has any body implemented a method by which the client can connect via a tcp (e.g. HTTP) gateway to the keyserver (the latter connection presumably with UDP)? This might come in handy for people behind firewalls, so I ask if it has been thought of or done. Even an email gateway would be useful... I have not proved (no source code) that the deschall client uses UDP, but I believe it does (as did the RC5 48 bit client). I understand UDP's connectionless socket is superior to TCP for this type of application, but I am wedged with UDP. Short of this could somebody tell me the UDP port number the client uses? I don't want to, but I might be able to rig up some perl scripts on both sides of my connection transmitting the UDP information.

There are actually a number of things that I'd like to see done, in order to increase the number of clients we can get running. * Support for HTTP proxies. The number of machines behind corporate firewalls is huge, and this provides a very standard way for them to access the keyspace server. * Support for occasionally-connected machines. This would get us access to lots of other machines on the other ends of dialup-type PPP and SLIP links for lots of folks at home. Actually, I rather like the design of the system that the group that found the 48-bit RC5 key for their coordinated DES search. Lots of clients are supported, there's some simple checks to get some confidence level that the keyspace that the client reports searched actually has been, there's a hierarchy of servers, etc. But they aren't done building everything to their beautiful specification :-) Actually, I haven't heard anything on any of those lists for a while now, probably two weeks, so I'm not sure that any real work is actually being done. Perhaps we can borrow some of these ideas to make our search a more effective one? -- Matt Curtin Chief Scientist Megasoft, Inc. cmcurtin@research.megasoft.com http://www.research.megasoft.com/people/cmcurtin/ I speak only for myself Hacker Security Firewall Crypto PGP Privacy Unix Perl Java Internet Intranet From owner-deschall Sat Mar 29 23:42:44 1997 Received: (from majordom@localhost) by gatekeeper.megasoft.com (8.7.5/8.7.3) id XAA05864 for deschall-outgoing; Sat, 29 Mar 1997 23:42:44 -0500 (EST) Received: (from uucp@localhost) by gatekeeper.megasoft.com (8.7.5/8.7.3) id XAA05859 for ; Sat, 29 Mar 1997 23:42:43 -0500 (EST) Received: from chatlink.com(205.139.105.61) by gatekeeper.megasoft.com via smap (V1.3) id sma005857; Sat Mar 29 23:42:22 1997 Received: from sector.com (cl2-p8.chatlink.com [205.139.105.217]) by chatlink.com (8.8.5/8.8.5) with SMTP id UAA13558; Sat, 29 Mar 1997 20:46:20 -0800 MIME-Version: 1.0 Date: Sat, 29 Mar 1997 20:48:45 -0400 To: cmcurtin@research.megasoft.com cc: deschall@gatekeeper.megasoft.com From: "Andrew James Alan Welty" Subject: Re: TCP gateway?

This is already supported in a way, dialup users can at least run deschall while there connected to the internet, even keep it running and reconnect after it finishes and needs a new key to try. More support could be implemented though, my idea for this would be to have the server release a block of keys for the system to work on while it's away from the internet. After reconnecting to the internet, the client would send all completed keys out of the block to the server, and if necessary request another block.

Such a thing would really not be very difficult, Karl. [I just don't have the time.] The protocol, as seen by the gateways is mighty simple: The client sends 1 packet to the server. The server sends 1 packet back to the client. The transaction is over. To increase fault-tolerance, if no response is received, the client retries at increasingly lengthy intervals, much like the old RC-5/48 clients did. Is there no shareware (or commercial package) that already exists that can encapsulate (and unencapsulate) UDP packets inside TCP packets? > There are actually a number of things that I'd like to see done, in > order to increase the number of clients we can get running. > > [snip -- see Matt's post] > > -- > Matt Curtin Chief Scientist Megasoft, Inc. cmcurtin@research.megasoft.com Matt, I agree with most of your ideas. No offense intended to the RC5-48 crew, but I'm happy to be testing keys while we begin debate about such extensions. :-) There are a lot of CPU cycles available outside the USA, so here are 3 more wild ideas that I don't have time to follow up on: Is there any lawyer-type-person, EXPERIENCED WITH CRYPTO EXPORT, who would care to see if the clients can be exported without a license? The object code does not perform encryption or decryption per-se (it takes one 8-byte block of known plaintext and one 8-byte block of known ciphertext and attempts to find the correct key.). But the function does not quite fit any of the exemptions explicit in the new EAR regulations, either. DO NOT THINK THIS TASK IS EASY! Read some of the [horror] stories at the EFF Web Site. Is there a reputable publisher, who would care to publish the source code? I seriously doubt any publisher's time-frame is compatible with this project. It's just an idea. [Didn't MIT Press publish the PGP Source Code?] Would anybody outside the USA/Canada care to adapt their own code to use the DESCHALL protocol. Understand that US Export Law would make this a very frustrating process, with many one-sided conversations. Once done, however, nothing prevents the DESCHALL server from passing keys out around the world.

To better support Slip clients I would suggest the following changes from easiest to more dificult: Allow much larger key ranges to be requested. My 200MHz Pro does 2^30 in 2251 seconds. If I could get 24 hours worth of keys that would help. I have two more machines now and soon could have several more... my current ISP does not allow a gateway arangment, I tried to setup masquarading on my Linux server but effort vs. rewards at the time made me give up after several days effort :-( A system that used files or email would allow these other machines to participate. I know this asking time of those who have given much allready, but I though I should at least layout a couple of ideas. Again thanks to all.

We're 1/10 of a percent through the keyspace (let's have a party at 1%!). We seem to be getting attention via word of mouth, and most of all, we have a lot of different organizations beginning to show interest. Once we have a few people within a given organization, it is usually fairly easy to pass word around and get more machines running. I was the first person here at .orst to start running the client (on my laptop at home) after reading about it on one of the crypt lists that I'm subscribed to. So far we've managed to get the lab I work for to contribute significant cycles to it, and the college of business let us use their machines for spring break--all we needed to do was ask. We're working on getting the Computer Science and Engineering departments behind us as we speak. Unfortunately, abour 100 pentiums go back to running login screens tomorrow morning, so I expect that our keys/day will fall considerably. One of the things that made it so easy was the simplicity of the client--just run it and go. We ended up putting it into login scripts for most of the computers, making it trivial to fire up 100+ machines. We might be able to do this every evening when the lab closes. However, it would be nice to have more client options. It has been said that clients should be able to check out a larger set of keys (perhaps a day's worth) at a time, or use other methods of accessing the keyserver. Right now, network traffic at this end is negligable, but as we get more and more machines sending a request every 30 minutes, we're going to hit the keyserver harder. Has anyone figured out how many clients it can handle? How is it holding up? It might be worth it to make the auto-ranged keysize adjustable so that our steady clients don't hit it so often. Do we have a bi-directional protocol of any kind of the server? If we could have the client query the server for progress stats, we could write a cool screensaver that people would sit and watch while it calculated keys. Even if we can't query the server, it would be a good way to make it easy for people to run the client--just tell them to install a screensaver, and every time they look away from the computer for 30 minutes, we get more keys checked. Does someone want to code this? Other options would be to have a Windows NT service, so it could run under an NT login screen. Also, has anyone been tracking any of the other efforts? Are we ahead?

It doesn't make sense to search already-searched keys. Perhaps the keyserver can be instructed to import a file of key ranges that have already been searched. Alternatively, perhaps the keyserver can be "fooled" by a client that uses key ranges published by other projects to indicate that those keys have been successfully searched. I'm not saying we literally try to fool the software, but just thinking of quick 'n dirty ways to legimitately make use of known searches with a minimum of programming effort on Rocke's part. Then again, there is the issue of how reliable these searches are. I'd hate to think that anyone out there is faking successful searches just to boost their prestige, but it could happen. Perhaps importing other people's searches is opening ourselves up to abuse.

I think we've covered more keyspace than the sum of all other reported efforts, and we're growing the fastest. Assuming that this trend continues, energy would be better spend encouraging more people to join...

I want to release this on Wednesday of this week. If it requires more time to fix up, then I'd like to have it out as soon after that as possible. Looks good so far. DESCHALL Group Searches for DES Key [DRAFT] (will say ``for immediate release'' here one day) [DRAFT] In answer to RSA Data Security, Inc.'s ``crypto challenge,'' a group of students, hobbyists, and professionals of all varieties is looking for a needle in a proverbial haystack. The ``needle'' is the cryptographic key used to encrypt a given message, and the ``haystack'' is the huge pile of possible keys: 72,057,594,037,927,936 of them. Might want to explain a little more about this, may mention the prize, might entice some more people to at least give it a try. The point? To prove that computing technology is sufficiently advanced that such a search is feasible using only the spare cycles of general purpose computing equipment, and as a result, unless much larger ``keys'' are used, the security provided by cryptosystems is minimal. Conceptually, a cryptographic key bears many similarities to the key of a typical lock. A long key has more possible combinations of grooves than a short key. With a very short key, it might even be feasible to try every possible combination of grooves in order to find a key that matches a given lock. In a cryptographic system, keys are measured in length of bits, rather than grooves, but the principle is the same: unless a long enough key is used, computers can be used to figure out every possible combination until the correct one is found. In an electronic world, cryptography is how both individuals and organizations keep things that need to be private from being public knowledge. Whether it's a private conversation or an electronic funds transfer between two financial institutions, cryptography is what keeps the details of the data exchange private. It has often been openly suggested that the US Government's DES (Data Encryption Standard) algorithm's 56-bit key size is insufficient for protecting information from either a funded attack, or a large-scale coordinated attack, where large numbers of computers are used to figure out the text of the message by brute force: that is, trying every possible combination. Success with this project will prove such postulations correct. The effort is being coordinated through a web site at http://www.frii.com/~rcv/deschall.htm. Many more participants are sought in order to speed up the search. The client software is available through the web site. One simply needs to follow the download instructions to obtain a copy of the software. Once this has been done, the client simply needs to be started, and allowed to run in the background. During otherwise wasted cycles, the computer will work its way through the DES keyspace, until some computer cooperating in the effort finds the answer.
