Subject: Any cypherpunks building encrypted phone?

Hello everyone! I'd like to know if anyone on the list has made any attempt to construct a true encrypted phone, something at the level of the AT&T DES phone. I think that it ought not to be too difficult to build a couple, using existing modems and basic hardware design. If all the commercial phones are going to be Clipper-based, we'll have to build the real ones ourselves.

I am working on that exact problem. It is not really that trivial. The encryption has to handle a lot of data real time. I have a license agreement for IDEA and am working on RSA. I am thinking of using tripple DES rather than IDEA because of the cost of the IDEA license. Two questions. One: Does anyone know of a good source of DES chips? Two: How much would you pay for a good encrypted phone? -----BEGIN PGP SIGNATURE----- Version: 2.3a iQCVAgUBLa4m2FVkk3dax7hlAQF4vwP+KppgEM/05FsVJoonnDQrLKcaRJxqvt8y CgJ5OgaFNwAdsJJyQ25SfxaaubP/Q/Ncz3os2ECdxFDGiVOk97tg6DvTfXA5QoSw hFYuKb+7W/KK455I8WdZkeX6O6T/cLDqe94pcJSLSKo2mqwuGUaZ3jdKLAthPtOE DjqkjZettOM= =34Dg -----END PGP SIGNATURE----- -------------------------------------------------- Lance Cottrell who does not speak for CASS/UCSD loki@nately.ucsd.edu PGP 2.3 key available by finger or server.
