Just received a low budget brochure from SVC offering their "Secure Voice" TM software for $250. Used with a '386 minimum, a Sound Blaster board, and a 14.4K V.42 modem they claim to do compression and DES encryption (triple DES with a '486). "You talk into your computer, the computer digitizes your voice, encrypts it, transmits it through the high speed modem over the open phone lines to the other end, where it is decrypted, and can be heard." They indicate you need one "Secure Voice" for each end so I'd guess they have it copy protected. "No BS Updates: ... As a purchaser, you are entitled to free software updates for the life of this product. We keep no records of who purchases our products, so to receive your update, send us your original disk and a SASE."
