Re. the digital wiretapping "compromise." As a telecom professional I absolutely resent and will resist any attempts to mandate backdoors into my PBXs. No compromise on that. Period. We've all heard the arguements many times: vast surveillance power, diminution of privacy, potential major security problems... I'd like to suggest something of a compromise which doesn't have these risks. Common carriers (local and long distance telcos) are currently required to provide access to line terminals when presented with a court order for a wiretap. This access could reasonably be extended to requiring the telco to connect a demultiplexer in the case of digital transmission, or some kind of appropriate signal splitter in the case of fiber optics. The agency requesting the tap would of course pay the bill for materials and labor. Now this gets law enforcement their demultiplexed signal path so they can tap only the intended target line, but it preserves the existing structure which prevents law enforcement "hacking," since no backdoors would be involved. For PBXs (this is my department), a slightly distasteful but acceptable compromise would be to have interconnect companies (the folks who install your PBX or key system) register with the local operating telcos, providing the interconnect company's name and contact information on the telco record for each subscriber. So for instance, General Widgets has XYZ Telecom install a new PBX; XYZ Telecom is required to inform the local operating company that they have just acquired General Widgets as a client. Now if a law enforcement agency gets a court order for a tap, they go to the local telco and ask who the interconnect company is for that subscriber. (We're talking here about a scenario in which one or a small number of extensions in a phone system are believed to be used for criminal purposes, so law enforcement has to tap those extensions only and not everyone who is on that phone system.) Now law enforcement visits the interconnect company and presents them with the court order, which requires the interconnect company to provide access to the line terminals of the suspect extension(s), and/or provide a demultiplexer etc. if needed (at law enforcement's expense of course)... and of course, under penalty of contempt of court, refrain from disclosing the situation to the client. Now this gets law enforcement their legitimately needed access to suspect extensions on PBXs, prevents interconnect companies from blowing the whistle to their clients, and still preserves privacy protections since there is no backdoor into the system. Now here is why I think the FBI wants backdoors: Recall that under the "war on drugs" etc., a ruling was handed down (I can't recall which branch of govt originated this) which says that a wiretap may be conducted for up to 72 hours for "investigational purposes" without a court order; and the material recorded may then be used to go and get a court order for a continuing wiretap. This places authority in the hands of law enforcement agencies to conduct taps any time they suspect someone of something, and then go see the judge after the fact. Now without backdoors, law enforcement has to depend on the goodwill of telcos to get access, and is kind of stuck when it comes to PBXs and key systems. I'm willing to bet there is a pretty substantial amount of "investigational" tapping going on, and that the FBI is interested in vastly expanding it. The compromises I'm proposing don't address this investigational tapping, and that's just fine, since that ought to be challenged in court or defeated one way or another. -gg@well
