And now for something different regarding crypto: In studying for my FCC Technician's license I ran across FCC 97.113 (Sub-part 113 of Part 97 of Title 47 Code of Federal Regulations), which prohibits the use of codes or ciphers to obscure the meaning of a message. Besides preventing me from using Pig Latin in voice communications, this *seems* to prohibit the use of any deliberate encryption (as opposed to compression) of data transmitted via radio, such as the computer packet -> radio -> Internet gateways. The data highway may be encryption-tolerant today, but the off-ramps are murder. :-) M ----------------------------------------------------------------------------- Michael S.
