Do any of you have a current list of banned mathematics topics handy? I was reading a number theory book (Rosen) and got worried that I might be stumbling into some of the areas forbidden to private citizens. I have e-mail in to Professor Denning, author of the Index, for guidance on what mathematics is and is not allowed, but she has not yet responded. Meanwhile, until I hear from her or get a special waiver, I've put the book away. I'm hoping that Rosen's introductory text is not treated as "crypto paraphernalia," even though it's sold over the counter at Computer Literacy, Stacey's, and other such "head shops." --Tim, getting more worried after the arrests at Amateur Crypto BBS, where the owners received an unsolicited data packet from Tennessee and were then prompty arrested by the Data Police -- ..........................................................................
