This is called an active location system, and it was originally disigned by G.K. O'Neill (The Princeton Physics Prof., Space Studies Institute founder, the guy who came up with all those spiffy space-settlement ideas in the late seventies -- see Babylon 5 for a picture ;-) -- and the inventor of the mass driver, among other things), under the name of Geostar, in the early 1980's. It's accuracy was supposed to be 6 inches in 2 dimensions, and 6 feet in 3 diminsions. The FAA didn't like it because they didn't invent it, the DOD hated it because they wanted to commercialize GPS and they didn't want anything so accurate for civilian purposes. The transponders were going to be beensy little things about the size of pagers relying on high-energy burst transmissions. ObCrypto/Privacy: It relied on a fast computer on the ground to calculate where you were, it allowed short messages, and presumably it was going to send them in the clear. It also had a "panic" button function, where someone in trouble could summon help no matter where they were. ----------------- Robert Hettinga (rah(a)shipwright.com) Shipwright Development Corporation, 44 Farquhar Street, Boston, MA 02131 USA (617) 323-7923 "Reality is not optional." --Thomas Sowell >>>>Phree Phil: Email: zldf(a)clark.net http://www.netresponse.com/zldf <<<<<

Mmmh, correctness does not mean "it's a nice thing". It just means that something fulfills the specs. Do you know which specs were fed into the prover? The specs could be as weak as - RSA must terminate if fed with the number 42 - x ^ (e * d) = x mod n for all x from 0..(n-1) Hadmut

Hello Jim, I apologize that I didn't answer immediately. I have subscribed to several mailing lists and sometimes get some hundred mails a day. I don't have the time to read everything and therefore I have to select. I didn't read this thread, but I found it in my archives. > I wonder, and perhaps my kind friend Hadmut can help me here, if there is > an English translation of any and all Nazi-era German laws/regs regarding > cryptography.

These laws, if > they exist, might make for interesting reading in side-by-side comparison > with either Sen. Grassley's latest proposals, or with anything regarding > cryptography coming from our paranoid FBI director. I fear I have to disappoint you. :-( First of all I don't know of any english translation of such laws. The only english translation of law I know about is the translation of our current basic law. It might be easier to find english translations in english or american libraries than in german libraries. Second, I don't know whether they had a certain law about cryptography. AFAIK Enigma was a commercial product first and was taken over by the government. But I don't know they way they did. Third, there was no need to have laws. I don't want to restart the discussion, but the Nazis didn't understand laws as so important. I have read a book about their justice some time ago. The 'idea' and the 'public feeling' was seen as more important than laws. But perhaps another telecommunication law may be interesting. It was forbidden to receive foreign radio senders. If they came into the house and the radio was tuned to foreing frequencies, you got into serious trouble. I just don't know where to find the text of the law. regards Hadmut

NIST/NCSSC National Information Systems Security Conference
by droelke＠spirit.aud.alcatel.com 17 Dec '03

A couple of days ago I got a booklet about the "18th National Information Systems Security Conference (formerly the National Computer Security Conference) " being held October 10-13 in Baltimore. Just a little excerpt about it: One of the tracks is "The Internet and Beyond" Several of the sessions look rather interesting. The "Management and Administration" track includes at least two sessions by D. Denning of Georgetown Univ. One of them is "Legalities: Will Encryption Keep Out Hackers" and the other is "Critical Factors of Key Escrow Encryption Systems". The first of those has a panel of S. Bellovin of AT&T, M. Higgins of DISA, S. Kent of BBN, and E. Spafford of COAST. So, is this a converence that is really worth something, or something that the management heads might learn something at? ;-) I guess that ordering my personal set of the Rainbow books gets me on more lists than I thought :-) Dan ------------------------------------------------------------------ Dan Oelke Alcatel Network Systems droelke(a)aud.alcatel.com Richardson, TX http://spirit.aud.alcatel.com:8081/~droelke/

Secret Service Says Student Used PC To Print Money Lubbock, Tex., Aug. 3 -- PC graphics programs have come a long way since their inception, but not far enough to fool the Secret Service. That's what a Texas Tech student tried to do when he used his personal computer to print counterfeit money, according to Secret Service agents. "He really put his whole heart and soul into it," according to Lubbock, Texas Secret Service Resident Agent David Freriks. Freriks said the man is an engineering student at Texas Tech, but told agents he plans to change his major to computer science. The 20-year old student hasn't been identified by name since he hasn't been formally charged yet, according to Freriks. But officials apparently aren't concerned that he will flee. "At this point, he's more afraid of his dad than anything," said one agent. Freriks said the Pakistani national, who resides in affluent southwest Lubbock, scanned a real $50 bill into his PC, then printed the image to an Epson inkjet color printer. Agents said the money looked real at a distance but up close the designs were blurred, the coloration was faulty, and the paper was slick and didn't have a watermark strip. Freriks said agents are confident that all of the approximately $3,300 that was circulated has been recovered except for about $1,000 which he said he is sure will show up eventually, since the quality makes it easy for bank employees to spot. ... Investigators seized the home computer, printer and scanner from the student's home. They said they also found a suitcase containing almost $260,000 in fake $50 bills. --

IPng6, SWIPE, ssh, etc.
by sdw＠lig.net 17 Dec '03

I would like some summary opinions of the state of various efforts to enable full IP encryption. I'm looking for progress reports and hints as to which technologies are the closest to being implementable. After playing with ssh, I've been thinking of what it would take to start migrating certain links to full encryption, possibly using a VPN-like arrangement. I'm interested in hacking Linux, loopback userspace drivers for other Unix's, and thinking about what would need to be done for MS-BLECH. Of course, firewall like conversion of IP<->IPng6 would be great. Of course now that Linux has IP aliasing, IP masquerading (partial I think), ipfw, and IP over IP tunneling, it has much of what it needs. I'm just considering development and migration paths. I haven't kept up on IPng6 docs, so succinct pointers would be helpful. One interesting tact might be to start running a dual IPng6/IP stack where it learns to tunnel packets over a well-known IP udp/tcp link if an address doesn't respond to IPng6. sdw -- Stephen D.

>Secret Service Says Student Used PC To Print Money etc. This reminds me of something which happened to me last week in a Burger King in Chelsea(MA), where the skipper now keeps the boat I grind winches on. I'm paying for my lunch and the cashier takes out a felt-tip pen and puts a little mark on my $10 bill. She tells me that if the pen-stroke turns yellow instead of the black one she got with mine, the bill is counterfeit. She told me she got yellow mark on $10 bill once. Go figure. So now, we have a working miniumum competitive cost of on-line digital cash verification. The amortized cost of the ink it takes to verify a piece of paper cash. What? 20 cents worth of ink? .002 cents? More fun with numbers, Bob Hettinga P.S. We just put in 12 volt power for the Mac. I also bought an inverter. Banana daquiris on the hook.
