Look Ma, No-Hands Fasteners! 200

Posted by CowboyNeal
from the assembly-liners dept.
theodp writes "Inspired by a daughter who suffered a serious infection from an IV feeding apparatus, the Trib reports an Australian architect has developed high-tech bolts and latches, which can be operated remotely without being touched. The first commercial applications are intended for aircraft, allowing crews to quickly reshape interiors to maximize payload space. BTW, smart fasteners hit Slashdot's radar almost two years ago."

    Now, I think this is really nifty, but... its easily hacked. Why? Because anything transmitted over open air can be hi-jacked. They claim otherwise, but I find it hard to belive that a unit thats small and simple enough to replace standered fixing devices (like bolts) would be smart enough to handle and nearly unbreakable encryption scheme.

      I wouldn't think that it would be too hard to key them with, say, 1,000 keys, 128 bits per key. That's 16,000 bytes, and 3.4 * 10^38 odds against you per guess. (I'll wager I don't need quite so many bits per key.)

      The procedure is this: (1) Listen for my address to be spoken. (2) Listen for fasten/unfasten command. (3) Listen for password.

          The scenario is that these mechanics are working on these aircraft in a controlled physical environment. So your attack makes no sense: If someone's using one of these devices to attack your bolts, you just look for the device. It's a freakin' lighthouse, and shouldn't be hard to locate.

        Capitalism is an equal opportunity for wealth.

        You seem not to realise that the quote above is the direct outcome of the one below. The ultimate purpose of Capitalism, from a perspective of a powerful participant, such as a multi-national corporation, is to enslave everybody who can be enslaved by making them dependant on your products and destroy or marginalize the rest, by any means one can get away with. An ability to deprive the consumers of control of the things they supposedly own, or ensuring that such things have built-in obsolesence and are as disposable as possible, to be replaced with even less controllable and more disposable "goods", are perfectly valid strategies from a purely capitalist perspective, where greed and bottom line are the only overriding concerns and where definitions of the nature of "private property" are simply naive holdovers from earlier, simpler times and easily circumvented by technological chickanery.

    From the article:
    "What Rudduck developed are fasteners analogous to locks in doors, only in this case messages are sent electronically to engage the parts to lock or unlock. A quick electrical charge triggered remotely by a device or computer may move the part to lock, while another jolt disengages the unit.

    Instead of nuts and bolts to hold two things together, these fasteners use hooks, latches and so-called smart materials that can change shape on command."


    This sounds like nothing more than radio controlled solenoids, similar to what we see in remotely controlled apartment building entrance doors and in automobile power locks. A solenoid is just a coil that is electro-magnetized on demand to push or pull a metal bar through it's center. This bar usually moves something attached to it or touches a contact to close a high current circuit loop, like in a car starter motor. My guess is that the solenoid in a "smart fastener" would push open a latch or release some hooks.

    So why all the talk about "smart materials", "intelligent bolts", and materials that "change shape on demand"? It sounds like a bunch of pie in the sky market speak to me, not unlike what is heard in articles written by corporate PR agencys. Such articles are often given to lazy, disinterested journalists as neat & easy pre-packaged stories.

    This story has no substance - buzzwords are rampant and technical detail is non-existant. Yet the slashdot editors are proudly proclaiming they broke the story 2 years ago. Even worst, the story is being pitched as using exotic technology that allows self-threading bolts of some kind. The same false pitch was used last time as well. I bet this sort of "mistake" generates lots of $$$^H^H^H click thoughs though.

Examples: piezo buzzers and liquid crystals.

    When I read the article, I was concerned not with the ease with which a third party could hack the radio signals, but with the problems this technology could cause for regular users who want to take apart their consumer products. If, as the article predicts, these RF fasteners make visible screws and bolts a thing of the past, to be replaced by internal, remote-controlled fasteners, the main result will not be opening up new avenues for design, but limiting users' ability to take apart their devices. In this dystopian future, only qualified service representatives might be authorized to use the coded signals to open up the case on a PC or a phone, for example. Or the fasteners could be rigged to electronically keep track of "tampering" or "unauthorized access."

You worked at the company, so figureing out the codes should be a no-brainer, they are probably as easy to hack as RFID.
