Throw the true random numbers into a hash function, and voila! they pass all the standard battery of tests. The hard part, IMHO, is figuring out how much true entropy you've got.

IANAL, YMMV. A more precise answer is "If you print it out, and ask them for permission, they may or may not grant it. If you print it out, don't ask for permission, and let them know you're exporting it, they may or may not decide to prosecute you, and you may or may not have the resources to win if they do." Dan Bernstein's reading of the law is that you can't even teach cryptomathics to foreigners in the US, and his court case on the matter is beginning. Other people read the law to say that public domain material is not "technical documentation" on defense items, and thus exempt. Putting a copy of the MIT book in some public libraries would be nice... #-- # Thanks; Bill # Bill Stewart, stewarts(a)ix.netcom.com / billstewart(a)attmail.com +1-415-442-2215 # http://www.idiom.com/~wcs Pager +1-408-787-1281 !

Patient medical files on Net
by Martin Diehl 17 Dec '03

17 Dec '03

WSJ - 2/20/96, page B1 "Click! Doctor to Post Patient Files on Net" by G. Bruce Knecht "An audacious experiment ... [snip] "Deep in the heart of Appalachian coal country, a doctor is about to put his patients' records on the World Wide Web. The Doctor, Bruce Merkin, works at a community health clinic in Wayne, W. Va." [snip] "Dr. Merkin and Vasudevan Jagan-nathaniel, a West Virginia University professor who is responsible for developing the software for the system, say they have yet to decide how secure the system should be. At one extreme, they could encrypt the information, offering the highest possible degree of protection. But encryption is expensive and time consuming and thus could hinder the goals of cutting costs and rapidly transmitting information." [snip] Cypherpunks: The WSJ report seems to indicate that the system is to be deployed without any encryption safeguards. After talking by phone to Lee Oxley (oxley(a)vhs.wvu.edu) at Valley Health in Wayne, WV, I got clarifications of what was in the WSJ story. The present pilot system is an intranet system with dedicated frame relay links and does use encryption. Eventually they may deploy a system that would be internet based. They are considering how much protection to put into the system. The reference in the article about encryption costs was intended to be about CPU cycles not dollars. Vasudevan Jagan-nathaniel's email address is juggy(a)cerc.wvu.edu Some obvious proposals would be to use something like SSL to do server to workstation encryption. I don't know what issues may exist such as the effort to install SSL, key management, and processing delays due to session keys and traffic encryption. In addition, how could an on-call doctor access patient records through an ISP and maintain patient privacy. An obvious issue (which I know have been discussed on this list) has to do with the trade-off between key size and privacy. Any other thoughts? Martin G. Diehl

An amplification mechanism will usually couple the signal to the vacuum, and introduce vacuum noise. Another way of thinking of vacuum noise is that amplification mixes the state of the signal, with the (unknown) phase of the universe at infinity.

In <199602200851.DAA02057(a)thor.cs.umass.edu>, Lewis mentioned: > Could you explain what the acronyms "ADC" and "LOB" mean here ? I [and] > I might guess that LOB = Low Order Bits. Now, I'm way (WAY) over my head on this forum wrt crypto. However, an idea -- ADC might mean Analog Digital Converter. LOB might mean Low Order Bit (singular). So, IPG may just be watching the LOB of an off-the-shelf analog input card. Rash speculation, of course. However, if true, a Novitiate Crypto Wizard might be prompted to ask: "Assuming I use an audio source to drive the ADC, which of the following would yield higher entropy?: * Greatfull Dead * Al Gore speeches * The Beatle's White album (at 78, backwards) * The hiss after the local AM station shuts down for the night. " :-) -jim P.S. My name is Jim Bostwick, I hate big SIG files, and my employers opinion might actually coincide with my own - but probably not.

The meeting will be from noon to 6pm (or so) on Saturday, 9 March. As of this notice, there is no agenda. (Funny, we never seem to be at a loss for words.) Street parking is scarce, garages are expensive; consider public transit. If anyone wants BART, CalTrain or bus information, let me know. Otherewise, here are driving instructions: PENINSULA --North on 101 (or 280 to 101) to Golden Gate/Bay Bridge fork. --Right on 80 (Bay Bridge, Oakland) to 4th St. exit. --Take 4th St. exit. --At the bottom of the ramp, go sort of straight (soft left) onto Bryant (parallel to 80, towards Bay). --Take Bryant about 4 blocks to Fremont. --Take Fremont about 5 blocks to Market. --Follow instructions under "END GAME," below. EAST BAY --Take 80, west across the Bay Bridge to Fremont exit. --Take exit and turn left on Fremont. --Take Fremont about 2.5 blocks to Market. --Follow "END GAME" instructions. END GAME --The building on the far-right corner is 388 Market. --Find a place to park. --Sign in at lobby desk. You are going to visit Simple Access on the 4th floor. --Take the elevator to 4 and follow the signs. --The phone number is: 415-296-2544.
