Why isn't there a cypherpunk-ish voice crypto system? I would have to guess that it has to do with compression. Compression, lack of CPU and baud rate and money for gadgets. Well I have been fooling around and I think we can get a punk-phone up real quick. My system: 286-12 2400 baud modem sound blaster With just this I can get poor quality recognition of speech, In realtime. With a 9600 baud modem and nothing more than CVD for compression algorithm, fairly decent speech is a snap for the dumbest CPU. Surely the crypto is a lead pipe certainty in realtime. I would like to see this minimal secure phone system SOON: hardware: 286 9600 BPS (7680 bits of data/sec) sound blaster software: CVD "push to talk" (one at a time, please) xor against prng If we got this up, then people could improve on it, add "real" crypto auto detection of faster cpu for "real compression" etc. My point is we have to have something to improve on. My 2400 baud 286 compression is poor quality, very poor. But interesting, it shows what can be done with nothing. If the general feeling is that it would not be too disruptive i could post a reconstructed speech snippet UU Encoded on this list. (.VOC)
