    Add a layer of encryptation to your packets. The government won't like having to waste extra time decoding your Slashdot traffic, so they'll just make it against the DMCA to encrypt your packets.

    Eventually, internet traffic today will be like people traffic. I'm sure if I wore a big cloak and walked down the street, the police would be nervous of 'what I'm hiding under there' and might be so inclined to ask me about it.

    While its legal to carry a concealed weapon if you have a licence, most people don't bother. So criminals and police alike can see that people aren't hiding a rocket launcher on their person or trying to move their crate of coccaine.

    if you think this is a transparent attempt to get IETF to appear to endorse a heinous activity (as I do) then you might want to write the IESG and/or the RFC Editor (as I intend to) and object to such publication. in order to avoid flooding their normal mailboxes, perhaps someone would like to set up a mailing list?

    Let's see if I have this right.. you broadcast your packets on a public network where you already assume anyone can potentially get access to them, then you worry about what happens when the government steps in and asks to receive a copy of those packets?

    Like what, the government isn't already part of "anybody"?

    I'm far more worried about entities that are not part of the government getting a copy of my packets. Flawed though their procedures, checks and balances may be, at least the government folks have some. What procedures, checks and balances are on the criminals?

      Not really. You don't actually broadcast packets, even at layer 2. In every case, there's a specific destination to the frame. It's like the gov't spying on your mail by opening them all in the post office. And while yes, they can do this, it requires a court order and probably cause to do so (someone back me up, I'm not actually certain of this fact).

      As for private entities, packet capture is a time consuming task to perform constantly. I know for a fact that the ISP at which I work moves about a terabyte a day thru the network I maintain. It's not cost-effective (and there's not really any juicy stuff to be garnered), so they (corporations) won't do it.

      Plus, the litigious backlash should ISPs start doing this of their own volition would be prohibitively expensive.

      No, actually the Constitution does not give the judicial branch of government the power of review.

      From the Court's website (supremecourtus.gov):

      "While the function of judicial review is not explicitly provided in the Constitution, it
      had been anticipated before the adoption of that document. Prior to 1789, state courts had
      already overturned legislative acts which conflicted with state constitutions. Moreover,
      many of the Founding Fathers expected the Supreme Court to assume this role in regard
      to the Constitution; Alexander Hamilton and James Madison, for example, had underlined
      the importance of judicial review in the Federalist Papers, which urged adoption of the
      Constitution."

      John Marshall, the first Chief Justice established the precedent of judicial review, and it has since become custom as strong as written law. The court's purpose has always been to interpret and explain the laws of the country, but if they put the kibash on something as unconstitutional, it becomes by decree unenforceable under the law(the court being the embodiment of law in the country).

      Class dismissed. :)

    Of course I'm concerned that they will be hacked. . .Which is why I advocate that the design of these intercepts be standardized and subject to a public RFC process.

    *Of course* we need a mechanism for *lawful* intercepts in this society. Some capability to (shall I say it again) *lawfully* monitor bad guys on the Internet is necessary to protect the rest of us, just as it exists in every other medium including human conversation. What I'm much more concerned about is half-wit J. Edgar Hoover wanna-bes who take an ad-hoc approach to collecting information, not giving a dump about collateral damage, and coyly taking an unregulated look at any other network traffic that "just happens" to get caught in their filters.

    I suggest that this RFC is just the right way to go about it:

    1. Publicly design a logical box that does what we need it to do and no more.
    2. Force the authorities to stay inside that box.
    3. Hand them their ass if they're caught outside the box.

    As for the /. write-up, it's just (increasingly common around here) ill-informed, let's-go-occupy-the-provost's-office hyperbole.

    What the privacy movement needs are intellectuals who can process enough complex facts to actually aid in the effort to balance a society that needs to be both free and safe. Automatically shouting "free!" when someone shouts "safe!" or "safe!" when someone shouts "free!" is not a useful debate. It's not even a good start.

  14. Usual Slashdot Readership Idiocy by Anonymous Coward · · Score: 4, Informative

    Many of the comments in response to this story demonstrate that the posters have neither read the referenced RFC nor understand the problem it is trying to solve. I'll restate it for the stupid or perpetually lazy among you (i.e. most of you who've responded so far):

    Telecommunications companies in many countries must by law provide "assistance to law enforcement" on occasion. Note: in many countries, not just the United States. This assistance has traditionally been in the form of providing call intercept and tracing on voice networks. Some governments in many countries now want to do the same thing for data packets, but moreover, when data networks are used to emulate "traditional" voice services, the existing laws already apply. Just because your ISP's telecom backbone runs over ATM or IP doesn't mean that they're off the hook when it comes to lawful intercept and emergency services (e.g. E911) regulations. When voice is extended to "the edge" in packet form, little changes in that regard.

    Now, that said, this RFC proposes an architecture to support tapping data (and any application layer-services that run on it, e.g. voice) in a uniform and scalable manner. Whether you like the idea of tapping or not is immaterial and irrelevant. Service providers must obey the law. If they cannot, they go out of business, or in some cases, never get off the ground. And make no mistake; this RFC is no more about "voice" than any other data service; it describes some of the special problems with enabling the enforcement of existing wiretap laws for packet voice, yet the aim of the RFC is to solve the general problem.

    The architecture proposed makes no assumptions about the use of encryption except that no assumptions can be made about the use of encryption; i.e. deliver "tapped" packets to the LEA as packets, not transcoded or decoded into some other format.

    For example, the Iraqi government used lack of privacy (informers listening everywhere) to deny its citizens freedom of speech (anyone who was overheard saying something bad about Saddam was hauled off to prison).
