re automatic online encryption of data from andersom spot colorado edu marc anderson also how about a box that you plug your phone into which would allow encrypted voice communications with someone who has a similar box digitizing input speech transmitting and decrypting on the other end i don t know how a public key system could work in this regard but it might heh heh i posted this just before reading all the clinton chip messages i guess they beat me to it anyway i think it would be a great idea to develop such a product perhaps in the underground as it would otherwise probably become illegal pretty quickly here it s really very feasible and shouldn t be too expensive all that s needed is a box with a phone jack on one side a dsp in the middle to do codec functions of speech compressed bytestream and an rs on the other side you d plug your phone into it plug the rs into your computer and have a good old fashioned normal modem on your other rs port the cpu in the middle would do the encryption with a version of pgp modified to work on a byte stream with v bis or better modems to carry the bytestream it should work quality would only be marginally lower than a normal telephone at the very highest price you could use one of those voice mail compatible modems to do the digitisation that puts an upper bound of about on the cost of such a box in practice you really ought to be able to get the price well below i could do it now in software on my cheap nasty home risc box acorn archimedes with the digitising microphone i bought for pounds if i knew how to write good speech compression software which i don t the reason it won t work of course is that hardly anyone will have one the only consumer equipment to have encryption will use the wiretap chip economics i m afraid however we can get about kcps throughput on the internet even with the bottleneck of a v bis modem when we get isdn for all ha ha ha and the new nren it might then be trivial to run compressed speech over a tcp ip connection on the internet perhaps we should start thinking now of a standard to keep voice on the internet compatible for everyone and side step the clipper stuff and use internet for all our phone calls in future joking g
