CIA Stashes
by John Young 17 Dec '03

17 Dec '03

Reuter has a brief story today about "80 secret U.S. weapons arsenals that remain scattered across Austria for 40 years after they were hidden in case of a Soviet invasion" for use by resistance fighters. It says the CIA stockpiled the weapons without telling the Austrian government. The Austrian paper Kurier quotes the U.S. Ambassor as saying the CIA only recently informed Congress about the weapons stash. Does anyone in Austria or elsehere have more on this? ----- In a related matter, on Friday C-SPAN 2 aired several hours of comments and proposals by intel experts before the US Commission on Intelligence Reform. Mephistophelean former NSA head Admiral Bobby Ray Inman proposed among other brain-wavers to reorganize the thirteen or so bloated, bumbling, cat-fighting intelligence agencies: 1. Establish a new International Operations Agency to combine all operations units -- civilian and military -- into one, separate from the CIA -- which he thinks has irretrievably lost operations credibility. 2. CIA to do all intelligence analysis, but no collecting, to avoid contamination caused by "ownership of the data." The military to do intelligence collection and analysis only needed for immediate operations. 3. FBI to do all counter-intelligence, domestic and international, with agents stationed overseas. 4. Defense to do all imagery. 5. NSA/NRO/???, though not named in open session, presumably would continue ELINT and SIGINT. 6. All this will be very expensive, he roostered, intelligence on the cheap is worthless. 7. The total intelligence budget to be made public but no further breakdown of how the the pot of gold is distributed to supplicants is to be confessed. Former Ambassador to China Tilley, a 25-year veteran of CIA operations, emphasized the importance of continuing Non Official Cover operations, which, he said, are invaluable very-long term penetrations. He cited those he set up in China as COS and then revisited fifteen years later as ambassador -- still ferreting deepest of demon red-commie secrets, he black-comicly glowered to the glazed-eyes. NOC, while very expensive, is crucial, he, too, parroted. For the full eye-opening pack of lies to replenish the pot of gold, Tilley co-conspired that a closed session was needed. But all the intel gold-digging experts testified to that, grinning malevolently, thus continuing the grand tradition of looting national treasuries top-secret cloaked by national interest. So, where are all those not-yet-reported CIA Non Official Cover stashes of gold bullion (or $100 bills) to pay the world-wide "resistance fighters" for illusory supremacy?

Lan Manager security
by lws＠transarc.com 17 Dec '03

17 Dec '03

Have you seen an analysis of the security of the LanMan authentication scheme? It strikes me as better than K4, but worse than K5. I wonder if you concur. Since Don and Ted have probably not seen this before, here's the technique as I understand it (summarized from the SAMBA docs). The password is uppercased and truncated to 14 bytes (or padded to 14 bytes with nulls). This is split (0..6,7..13) into two DES keys which are each used to encrypt a static 8-byte value. The resulting 16 byte key is stored at the server. To authenticate a connection, the server issues an 8 byte random challenge. I presume this is returned in the clear since the docs don't specify otherwise, but I haven't sniffed one. The randomness of the challenge doesn't matter so much if it crosses the network in the clear (though I can't understand why they did this), as long as the period of the generator is large enough to prevent replay attacks. The client then pads the 16-byte key to 21 bytes (with zeros, natch), splits it in thirds, {0..6}, {7..13}, {14,15,NUL,NUL,NUL,NUL,NUL}, uses each third to DES-encrypt the challenge, concatenates the ciphertexts, and returns the response to the server. I don't want to prejudice you too much by posting my own thoughts on this protocol, but here are a couple of things that should be obvious: 1. It doesn't hand back free samples of enciphered known plaintexts to all comers for offline attack. This is a Good Thing, unlike some other NOTABLE EXAMPLES. 2. This business with padding the keys out with zero bits really simplifies cryptanalysis. Where my limited expertise breaks down, is identifying just how easy it makes things. 3. I'm kind of boggled as to why they do this multiple encryption of things and then *concatenate* the ciphertexts. If you're going to do multiple encryption, it seems to make sense to pipeline the stages. Doesn't it?

(fwd) e$: PBS NewsHour, Path Dependency, IPSEC, Cyberdog, and the Melting of Mr.Bill.

I thought I'd crank this out in light of Friday's NewsHour segment about Apple and the path-dependency of the microcomputer market. Contrary to what PBS would have us believe, ;-), the concept of path dependency in technology, and in economics, for that matter, is a proven fallacy. At the risk of sounding credentialist (*I'm* not an economist, either), the NewsHour's Mr. Solman seems to be proof that journalism isn't economics, no matter the journalist's academic credentials. Journalists have to get a story out, and sometimes there's no story in the actual economics of a situation. Certainly there's no story in the non-existance of path dependency. The most famous example of path dependency, the idea that our previous economic choices doom us to repeat those choices forever, is the QWERTY keyboard, which has been proven *not* to be significantly slower than the Dvorak keyboard, its supposedly more efficient alternative. Dvorak, the designer of the alternative keyboard, was also the same person who conducted the "ergonomic" studies (spending our WWII tax dollars, I might add) "proving" it's efficacy, and elevated his keyboard to the status of an urban legend. Dvorak was at worst a fraud and at best deluded with his own grandeur. Reviews of Dvorak's own data show some significant flaws in both research methdology and data handling. In addition, several independent studies since then have shown that randomly selected beginning typists, starting out on one keyboard or the other, have *never* shown any significant difference in typing speed. The Betamax/VHS videocassete war, another example of path dependence, was more one of Sony not having an open standard than anything else. Sony played dog-in-the-manger with it's own technology, and consequently ended up owning the most lucrative market on a profit-per-machine basis, the one in television broadcasting. It also means they were leaving big money on the table where the largest market was, in consumer electronics. Doesn't this sound familiar to Mac fans? Path dependence had nothing to do with it. Consumer Reports did comparisons at the time showing only a marginal difference between Betamax and JVC, and nowadays there is absolutely no percievable difference between the two. I now challenge anyone (including, unfortunately, Apple's own *psychologist*, quoted in the NewsHour piece) to *prove* path-dependence in the current market "hegemony" of Microsoft on the desktop. It ain't so. The reason that Microsoft has business computer market dominance today is *not* because of it's original *perceived* incompatibility with legacy mainframe equipment ("nobody ever got fired for buying IBM -- or Microsoft"). Technically, mainframe compatibility was a non-issue at the time. It certainly wasn't for the first 5 years of the Mac's life, anyway. Apple could have done something about the mainframe compatibility issue with simple marketing communications if they had paid any attention to it at all. Apple's heart was never in the business market. First of all, for all their lip service to business, they really weren't ever attracted to the idea of building better word-processing and spreadsheet boxes, even if they did have the best one, before Excel and Word moved to Windows, at the time of the big ramp up of the business microcomputer market. It showed in their attitude to most business people. Outside consultants and mavericks were always the heroes in Apple's commercials, and so outside consultants and mavericks were attracted to the Mac as a computing platform, but large businesses and conformists weren't. When compatibility with mainframes actually did become an issue, for the short time when people were offloading their mainframe data onto LANs, Apple didn't want to be there anyway. With the advent of LANs, Apple didn't build the technology to deal with LANs head on on their own turf, large corporations. Apple built peer-to-peer networks of collegial desktop machines. Unfortunately, they never paid attention to the bandwidth or the multitasking premia necessary for those networks to function properly from the high-volume user's point of view, and, so, when someone downloaded a file from your machine, and you printed something in the background at the same time, you suffered a performance hit if you tried to do anything else. Your mouse jerked around the screen, or your words wouldn't show up in a window as fast as you typed them. With PC file and print servers, this was less of a problem, because those two jobs were offloaded to a seperate machine, whose job it was to do nothing but run a printer, or to serve files. Since everyone had to be connected to these servers the local area network, or LAN, was born. On Apple networks, every machine is potentially a server for everyone else, and everyone is their own print server. Only after PC LANs became ubiquitous did Apple ever build servers of their own. Again, their hearts weren't in it, because they were more interested in the possiblities of more distributed, collegial, peer-to-peer networks. Fortunately, the first problem, network bandwidth, has been solved, because almost all Macs now come with ethernet, while the second problem, preemptive multitasking on faster processors, is being solved slowly. This is all very good for Apple, because peer-to-peer architecture is where the world's going to go anyway. The whole internet is a peer-to-peer, "geodesic" network, where each machine is optimized for it's own particular function, be it serving, or switching information. There is no central repository of anything. That has been Apple's view of networks since day one. If it's any consolation, we won't even need LANs to do business with, anyway. A couple months ago, I saw Netscape running in the bond trading room of this country's largest institutional trustee bank, of all places. In their case, Netscape beat Powerbuilder hands-down in a prototype development shootout. The prototype *was* the production version. Netscape can do anything from secure outside-the-firewall SQL calls to actually conducting cash commerce. Game over. By the way, Netscape is not special in this regard at all. So can any other sufficiently secure browser server combination. Either one, client or server, can be developed for a dime a dozen even now. This is especially true when compound document architectures come on-line, like Apple's Cyberdog, an internet implementation of their OpenDoc software object technology. The reason we won't need LANs is because the only real difference between a LAN and the internet is a firewall for security, and the need for clients to speak Novell's TCP/IP-incompatible proprietary network protocol. With internet-level encryption protocols like the IETF IPSEC standard, you won't even need a firewall anymore. The only people who can establish a server session with *any* machine connected to the net will be those issuing the digital signatures authorized to access that machine, no matter where those people are physically. When that happens, networks will need to be as public as possible, which means, of course, TCP/IP, and not Netware. It's like Heinlein's old joke about space, "once you're in Earth orbit, you're halfway to anywhere". So, once you've gotten *rid* of the firewall, you're everywhere. So much for the path dependence of the LAN market. What happens to the information concentrated behind those firewalls -- or proprietary software markets, for that matter -- when, because of strong cryptography, firewalls disappear? Remember what happened to those floating globs of grease in the detergent commercial? Surfacted away into little tiny bits. I can hear Bill Gates now: "I'm melting!, I'm melting!". Ding, dong, Mr. Bill is dead... Game over. Now you see why he's fighting so hard to be net-compatible all of the sudden. In this "decade of the internet", the [user interface, platform, desktop, LAN, whatever] is meat, and real life is on the net, to paraphrase William Gibson. For the time being, I have come to the conclusion that the Mac, at least as long as Apple makes most of them, is the computer for the "best of us", and, unfortunately, not "the rest of us". I've learned to live with that. I no more worry about Apple's prospects than I do about Porsche's. I expect that Apple management, like Herr Doktor Porsche, is just waking up to the fact that even though they designed the Volkswagen, they can't possibly mass produce them efficiently at a decent enough profit to advance the state of the art, which is really where their hearts have been all along. Sooner or later, Apple will go back to cranking out 917s, to demonstrate the power of the technology, 911s, for a more affordable version of that power, and 928s, for those of us who only want to look the part. ;-). Fortunately, there are lots of companies, like Power Computing, to produce those Volkswagens for those of us who can't afford Porches, and "Macintosh" won't mean just "Apple" anymore. So, for developers, and for me, a fully-credentialled Mac Bigot and camp-follower, the future for Apple means Cyberdog, because Cyberdog means breaking down large "glops" of information and software "grease" and surfacting them, fractally, into little bitty bits out into the net, where *all machines*, not just dumb Java-terminals, can use them better. It also means developing cryptographically strong internet-level security, so that anyone can talk to any machine from anywhere if they have permission to do so, and *nobody* with out permission can either get in or see what those authorized people are doing, with a packet sniffer, or worse, with a key-cracker. It means building into all network applications the ability to do digital commerce. That is, the ability to handle digital bearer certificates, like Digicash's ecash, and the ability to handle micropayments, like the MicroMint protocol or it's successor technologies. Imagine if your code could send you money in the mail, or if a router did real-time load balancing by changing it's micropayment price-per-thru-packet when traffic got too high or too low. The future of the net's going to be a strange place, indeed. Until that happens, I suppose Porsche parts is still a lucrative business, as long as developers keep in mind what business they're really in.

It sounds like a variant of the Haber and Stornetta work on digital timestamping, about which much has been written on our list (check the archives, and/or sections of my Cyphernomicon).

Re: NSA vacuuming down Internet traffic

alanh(a)infi.net (Alan Horowitz) asks: >Is there any open source - or otherwise - knowledge or speculation about >which words/phrases the Terra-cycle cpu's are text-searching *for*? If it >were your responsibility to eavesdrop on Iranian terrorists ... >... would you know for sure which words/phrases to key on? It >doesn't sound like a tractable problem to me. There are two parts to this question. First, how do you choose targets? It's been a few years since I read Bamford's book (when *is* the next edition coming out, anyway?) but I seem to remember that there is some sort of "committee" that agrees on what to aim at. It probably contains the usual collection of bureaucrats from military and civilian agencies. Despite the lofty budgets, even the NSA's vacuum cleaner has a hose of limited size. The committee allocates the available resources to prioritized objectives. You can probably predict targets by estimating political priorities and clout of the various agencies, and, of course, by watching CNN. Second, how do you ensure that you capture relevant traffic? I'm sure you start with the obvious -- look at traffic that's definitely relevant and set up filters to find more of it. While it's attractive to want to treat this as a state detection problem (message is/isn't relevant) you really want more of a signal analysis solution (measure likelihood of relevance). Also, a high priority target would probably have its hit behavior evaluated by real humans to ensure that the expected amount of relevant traffic is continuously sucked up. My first job, twenty years ago, involved a prototype speech recognition system under contract for Rome Air Development Center (a traditional cover for TLA research). The machine was supposed to go beep whenever a specified word or phrase was heard over the input voice stream. We joked about testing for the term "Russian Spy" but settled on looking for "Kissinger" instead. That let us run tests by listening to news broadcasts of the time. We built custom boards with Schottky TTL and a blazing fast 120ns cycle time. Times change, eh? Rick. smith(a)sctc.com secure computing corporation

Espionage-enabled Lotus notes.
by Trei Family 17 Dec '03

17 Dec '03

I've come up with a new term to describe the type of 'improved' security in the new International edition of Lotus Notes: 'espionage-enabled' It's specifically built for export, and has a backdoor to enable USG agents to read the messages more easily. From the viewpoint of a foreign purchaser, 'espionage-enabled' seems an appropriate term. If we spread this term sufficiently, we may be able to discourage the widespread adoption of this half-measure, and increase the pressure for good, unencumbered crypto. speaking only for myself, Peter Trei ptrei(a)acm.org

An IDEA whose time has come (Notes from the RSA Conference)
by Jonathan Zamick 17 Dec '03

17 Dec '03

Well the RSA Security Conference is over, and I finally had time to sleep. Thus, I'll give you all a bit of my impressions. First, there were a heck of a lot more merchants this year. Last year, there were about 400 people. This year it was 1100, with a couple hundred waiting. Thus the conferences were a bit more mixed in level of topic. (As one person put it, the more interesting the title, the more likely it is a blatant plug for a product.) On the other hand there were a number of great conferences too. Sadly, I was busy at the Consensus booth and didn't have time for many of them. Last year Clipper was the big issue, but export controls were predicted to be the big issue this year. This year export controls were the big issue, but certificates were predicted to be the big issue next year. Lotus got low marks in everyone's book for setting the precedent of giving the government 24 bits of their key. (As if France is going to be satisfied with that solution.) I didn't meet many Cypherpunks at this conference. Partially it may have been because I was dirt tired after planning the booth in only two weeks, and running it. They had a lot of nice giveaways. I have a metal backed dayrunner which is cute, an etch-a-sketch keychain which is causing rabid jealousy in the office, and a nifty t-shirt with the logo 'A good marketing organization listens to its customers'... then the picture of a woman on the phone w/ two spooks listening in.. finally 'We Hear You... Your NSA'. Needless to say, I like it. Anyway here is the point of the subject from this message. A while back I asked for all your wish lists. One of the big issues was making IDEA available w/ RSAREF. Well, I did even better, you can now license IDEA from Consensus whether you use RSAREF or not. This was the biggest hit at our booth. A number of groups saw a very strong, fast, Swiss block cypher as a nifty thing. Imagine, you can use 128 bits in Europe. Right now I'm trying to convince Ascom to develop a crippled version of IDEA to simply give away if anyone wants it for export. (Like most of the folk here, I don't see a 40 bit key as very valuable, but it is useful for companies which don't have contacts in Europe.) As a little promo, Ascom, the company which developed IDEA, and will be licensing it in Europe, announced a challenge. If you can break one ciphered message in the next year, they'll send you on a vacation to the Matterhorn, give you a nice dinner w/ the creators of IDEA, and be really impressed. :) Anyway, I'll be putting more information up on our web pages about IDEA. If anyone wants info on my Etch-A-Sketch keychain, feel free to send me some mail. If you want info on anything else, you can send email for that too. Take care all.

January 15th Fortune (don't normally read it, but I picked up a free copy) has a lengthy and evidently well-researched article bylined Richard Behar on the efforts of BFI, a large regional trash hauler and recycler, to break into the (by most accounts) Mafia-controlled garbage collection industry in New York City. Cypherpunk relevance: BFI is cooperating closely with the DA in helping to prosecute its allegedly mob-affiliated competitors, which raises a lot of very interesting questions, for which I have yet to formulate any answers. Also a sidenote about how NYC's disclosure laws actually aid organized crime by helping the various bosses track who owns what territory. Electronic surveillance. Money laundering. Steganography (sending messages by way of the disembodied head of a dog). Open access to information and free-market capitalism versus violent bozos, with and without uniforms. Pen trumps sword.
