One of the problems with Philip Zimmermann's very worthy voice encryption project is the lack of support for PC laptops, notebooks and palmtops that lack soundcards. If anyone involved in this project is listening, please consider creating a version that will work well with the PCMCIA "Wavejammer" card or some other peripheral soundcard substitute. Cogon Electronics Inc., as has been discussed in this group, markets a voice encryption program called Aquafone that employs Diffie-Hellman+triple DES. The current version uses a push-to-talk feature like a CB radio, but the company plans a fully duplexed version in March. Like the Zimmermann project, the Aquafone uses a standard soundcard. The company reports mixed results using Wavejammer cards. The audio quality afforded by the Wavejammer is noticeably inferior to that of a soundcard. Seems the audio digitization algorithms would have to be tweaked to optimize the fidelity using the Wavejammer. BTW, please don't misconstrue this as an advertisement for Wavejammer or Aquafone. I fully expect Phil's voice encryption software to become the de facto telephonic standard just as PGP became the Internet standard. Cogon's Aquafone, while commendable, has the disadvantage of employing DES. I presume Phil will select a more resilient conventional algorithm. Cogon also lacks Phil's cachet as certified by his fans at Justice and Customs. And, of course, the Zimmermann software will be freeware. Likewise, I mention Wavejammer because that is the only PCMCIA substitute for a soundcard with which I am familiar. If someone can suggest other solutions to the sound card deficiency in PC laptops and notebooks -- short of buying a Mac or restricting one's selection to the few PC portables that have internal soundcards -- please do. I don't regularly monitor this group, so I would greatly appreciate any replies by e-mail. This is an important problem to solve. After cryptanalysis, traffic analysis is the biggest threat to secure telephony. A readily portable PC armed with Phil's voice encryption program represents a real dilemma for traffic analysts since one or both targeted parties are no longer tied to specific telephones. I am neither a telecommunications expert nor a programmer. I am a civil liberties activist. Periodically, from the safety of the United States, I must communicate with people whose courage and idealism puts them in jeopardy of hostile parties. PGP is quite popular in such circles. As you might expect, Phil's voice encryption software is awaited with equal enthusiasm. ------------------------------------------------------------------------- To find out more about the anon service, send mail to help@anon.penet.fi.
