Appologia to those of you who've seen this already. Carl invites you to send email. I'd suggest some verbage about export controls for crypto. Jim From: carl(a)town.hall.org Subject: White House NAFTA Event Org: Internet Multicasting Service Channel: Internet Town Hall On Wednesday, October 20, the White House is showcasing the benefits of the North Amercian Free Trade Agreement (NAFTA) to American workers and the American economy. President Clinton and Vice President Gore will highlight American-made products which are currently sold in Mexico. The range of products, and the number of American workers who make them is enormous and the White House would like to present to the American public the benefits of increased trade with our neighbors. The White House has invited over 200 companies and their employees to bring their products to the West Lawn of the White House. Sun Microsystems is one of the companies invited and they would like to use this opportunity to highlight the computer industry in general as a crucial technology for our global economy and in particular to highlight the significant role the Internet will play in fostering trade in the global marketplace. Sun Microsystems, in conjunction with several other companies, will put two Sparcstations on the lawn of the White House. Using a Persoft Intersect Remote Bridge wireless 2 Mbps spread-spectrum radio link, we will link the LAN on the White House lawn to our facilities in the National Press Building. That network will in turn use the MFS Datanet national fiber backbone to link us at 10 Mbps to Alternet, our IP service provider. The workstations on the White House lawn will feature a variety of Internet applications such as NCSA Mosaic for X, Gopher, and other applications that highlight the scope and diversity of the global Internet computer network. Here is how you can participate! Send your electronic mail to: nafta(a)town.hall.org The mail will be collected and will be available on the screen as well as being printed out on a laser printer. Tell the President, the Vice President, members of the Cabinet, members of the Congress, and the national media what you think about NAFTA. Help demonstrate to this important audience that the Internet is an important forum for the discussion of public affairs. If you feel the need to flame pro or con on this subject, feel free to cc: nafta(a)town.hall.org in your discussions to the list. For general information on the Internet Multicasting Service, send mail to info(a)town.hall.org.

> You just have to fill out the right forms. Yes, of course, that's what I meant. There are no laws against skirting the paperwork if you are under the limit. Or, as you note, the "IRS 1040 list of foreign bank accounts" is another matter completely. Paul

Paul Baclace wrote: Well, obviously he should have taken tip from Ollie North and paid a courier to fly back and forth with $9500 at a time. No laws against that. Well, yes and no. As Perry pointed out, there is no limit to how much you can take out if you report it. The trouble is, though it is legal to take out less than $10,000 without reporting it, you can't perform a series of such transactions in order to ultimately move out an amount greater than $10k. They call it *structuring*, and it 'taint legal. Of course, structuring may be difficult to detect, so as a practical matter, you might get away with it. (If, however, you are found with $9500 in cash, they still might seize it under our wonderful new "fruits of drug dealing" laws.) But in any event, there are better ways to accomplish the same result. My favorite *fun* solution would be to buy $80,000 in travellers cheques and then *burn* them. I leave the rest of the transaction as an exercise for the student.

This results in >much better "randomness" than some keystroke timing techniques. True. You get even better entropy if you turn off the mic (or unplug it) and run the sampled audio output into compress -- assuming your mic is like mine and lets a bit of electronic noise sneak through every byte or two. The fan noise sounds random to us but it's relatively simple, in Fourier space. The same applies to fluorescent light noise. Although it's simple, it can defeat compress - so you end up with low entropy per byte. - Carl

Triple-DES strength (was Re: Monitor radiation overlooking.)

I suspect that you will get several comments about the proof that DES isn't a group. That doesn't apply here since you have not claimed that f() is DES -- only that it's DES-like. I would expect the strength of triple-DES to show up in Diff.Cryp. attacks, but maybe not. Meanwhile, I stick to my sci.crypt suggestion: compress|des|tran|des|tran|des If you could get more details from your KGB friend about that attack, there are one or two people here who would be very interested. :-) - Carl

Re:Glitches in PGP messages

To all who responded to my question about some truncation of lines in PGP messages, my thanks. It did indeed turn out to be a CR/LF problem. The problem being that there were none in the entire message! I looked at the messages I had been getting in my text editor and found the text to be one long line. I surmise that this has something to do with why PGP then truncates at line 16 of the ciphertext every time, interesting. My friend uses a program called POPMAIL to post with, which I now advise people to avoid. It seems to be hard to hack with a Mac. Thanks to y'all again. Scott G.

MacUser Security 1.1

I came across the following in the comp.sys.mac.etc faq under security: > If > you need to protect sensitive data I recommend that you encrypt it > with software such as MacUser Security 1.1. Does anyone know anything about this program and whether or not it is worth a damn? Would this be more on-topic at sci.crypt or comp.security? Walter Mitty <na26540(a)anon.penet.fi>
