If you're doing it for isolation reasons (keeping private stuff on your laptop instead of your Internet-connected machine to reduce breakin risks), it may be worth something. If you're doing it for TEMPEST, don't bother; laptops may put out less than CRTs, but I've still had my laptop emit signals that showed up on a nearby TV semi-legibly (out of sync, but Bad Guys can deal with that...) If you find a TEMPEST-shielded PC at an NSA Surplus auction, it'll probably be a 386 at best, and maybe a 286, so it may not be fast enough to bother with. Shielding this stuff is a Black Art, though paying a lot of attention to cables and boxes and tight corners with metal connectivity helps a lot. And just using a slower processor instead of that 200MHz microwave tower also helps. On the other hand, Matt Blaze has done some good work on cooperative encryption between smartcards and real computers, where the smartcard does a critical part of the computation and the bigger computer does the bulk of the work; you could still keep your secret keys on the slow shielded box. # Thanks; Bill # Bill Stewart, +1-415-442-2215 stewarts(a)ix.netcom.com # You can get PGP outside the US at ftp.ox.ac.uk/pub/crypto/pgp # (If this is a mailing list, please Cc: me on replies.

It was generated by a perl script, which emulates writing styles of different people. The way it does it is by keeping track of pairs of words and their most frequently used subsequent words. It reads articles (or any text really) written by the target person, builds the style tables, and then geenrates the "most likely" text. Carl starrs was a good target for two reasons, one of which is that he does not use punctuation. KIBO RULES!!! CLONING MADE EASY!!!

Dark Fiber Redux
by Robert Hettinga 17 Dec '03

17 Dec '03

Just to throw a little gasoline on the George Gilder "Dark Fiber" discussion around here, I found a huge, spiffy trove of Gilderama at: http://www.computer.org/internet/9701/gilder9701.htm Wherein the esteemed (at least I do ;-)) Mr. G says: > Remember that the fibersphere I've written a lot about is based on >wavelength-division multiplexing of tremendous amounts of bandwidth, which >can serve as a substitute for switches with all optical repeaters. And by >the way they've just developed fluoro-zirconate repeaters that can handle >the whole bandwidth of fiber. I don't know whether this technology will >actually prove out or not, but for the first time they have demonstrable >all-optical amplifiers that can handle the entire intrinsic bandwidth of >fiber, which is quite an amazing development in just a year or two. The >erbium-doped fiber amplifiers top out at 4.5 terahertz, so they can't >accommodate the potentially 25-75 terahertz that every fiber, >theoretically, could hold. What this means, of course, is that (kind of, as CDMA etc., counts a switching, I guess) like wireless, electromagnetic bandwidth, some day you'll have huge glops of non-switched fiber bandwidth to play with. In theory, at least, everyone gets a color, or frequency, and they listen on that frequency for their inbound stuff. If you want to send someone something, you literally tune them in and send it. Actually, I see these frequencies using CDMA carrier waves when it eventually happens, but you get the idea. The implications for cryptography are rather cool. I don't *think* these doped optical amplifiers interfere with so-called quantum cryptography (not to be confused with quantum computing, of course). If I remember my SciAm back issues, quantum crypto is cool, because if anyone touches the signal from Alice to Bob they're detected immediately. Or, is it that the signal drops? Can't remember which. Anyway, you need uninterrupted fiber to do QC, and that's what you have with optical non-switched amplification, whether you're disturbing the photons is another story. Anyone here know for sure? I remember discussion about this, but I don't remember the answer.

I used to have the usage of a virtual provider "Earthstar" and one morning to my surprise their wires had been disconnected by the telephone Company. I could no longer send out E-mail without being identified by the receiver of the E-mail and reported to my ISP and perhaps kicked off of my local provider. Then I ran across the coolest software that would assist me in sending E-mail and not being identified by anyone. Whether you live in a country that doesn't allow you to use free speech, your shy and want to send an anonymous love poem to someone, you want to advertise your product without losing your ISP account, or you just want to flame your boss without anyone knowing, then you may need the E-mail Cloaking Device. This 32 bit shareware program enables you to send anonymous correspondence all over the world. If you would like to receive a free demo copy of this great software, go to the Register page. Fill it out and put TRG Associates as your Sales Rep. go to the Register Page: http://www.hootowl.com/cloak/registerJ.htm And then GO TO: http://www.hootowl.com/cloak/emailJ.htm and download the demo version of Email Cloaking Device (ECD). It will allows you to e-mail up to 5 e-mails at a time. If you decide you want to e-mail more at one time, you can order the commercial version by sending your name, address, e-mail address and a money order for $299.95 To: TRG Associates P. O. Box 337 Greenville, TX 75403-0337 Phone 903-450-8809 The commercial version has no restriction on how many people you can send a message too at once. Also, the annoying message box that tells you of each message sent has been taken out so that you can push one button, walk away from your computer and send thousands of messages at a time. Also a very important point, we use this software and know how to use it and can offer you technical support. Good luck and may your next bulk e-mailing make you a million. Your Friend :-) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If you would like to remove ALL e-mail you consider junk then go to: http://catalog.com/tsw/efilter/ and download this program. It will do the repelling job for you automatically. Is this a great time to be alive or what? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Froomkin in the news
by Brad Dolan 17 Dec '03

17 Dec '03

A Moot-Court dry run of the upcoming CDT hearing by the Supremes was held Thursday in San Francisco and carried today by C-SPAN2. None other than our own M. J. Froomkin was one of the mock berobed ones. His vigorous pro-CDT probing of the ACLU anti-CDT guys was probably good practice for them, but he sure gave me the impression he really believed what he was saying. Brad ... Who has resolved to hold his nose and renew his ACLU membership.
