So for roughly $200 US, and a little software, it should be possible to put together something that would do encrypted voice communications over the network. Is there any interest in developing some sort of standard protocol and software to do encrypted, compressed voice communications over TCP/IP?
I don't know how many of you are at sites on the MBONE, or multicast backbone. There are already a few pieces of code out there for experimentation with transmission of audio and video information, in a variety of forms/encoding, and probably the most widely used tool, "vat - the Visual Audio Tool", already has provisions for carrying on encrypted audio teleconferences via IP. In fact, it's as simple as typing a key into a field, and the tool will DES en/decrypt the conference. --Strat, budding multicast weenie

Now all we need something which is a bit more general in its selection of the asymmetric encryption algorithm, and something which does public key for authentication and protection of the assymetric session key. - Ted
