Re: graphic archive A graphical archive for paper publication is a really wonderful idea. I can keep or mirror the electronic archive on soda. One of the projects that has been discussed is getting together a presentation that we can hand out to people who will present it at local meetings. One necessary for any presentation is graphics. Here are some suggestions: 1. What the 'channel' model is. Sender, Receiver, Eavesdropper. 2. How symmetric key crypto works over a channel. [The New York Times had a good graphic of this. My favorite part was that the secret information decrypted to "... and get a quart of milk. No, make that a half gallon." An excellent subtlety to show that privacy is for everybody.] 3. How public key crypto works over a channel. 4. How key escrow works. 5. How key escrow fails to work. Not neglecting the obvious, I would suggest that any drawings such as these, in whatever form they might have been created in, also be made available in postscript. Eric
