Lest this seem a little too reassuring, I would like to quote one of the members of the industry committee that established the standards for authentication and "privacy" for the new generation of digital cellular telephones. I asked why the government was so strongly opposed to the secure encryption of the over-the-air part of a cellular call when they could still go to the telephone company and tap the land side of the call where it connects with the regular public telephone network. The response? A warrant would be required to gain the telephone company's assistance, and warrants were considered to be "too impractical" in many cases. Draw your own conclusions. Professor Denning ought to spend some time in the real world before making proposals that implicitly trust the government to follow its own rules. Phil
