  • Cloning a VeriChip

    Yes, just because something's subdermally implanted doesn't make it secure:

    Been reading all sorts of crazy stories about these recently. I'd hate to have a subdermally implemented security measure get compromised and then go obsolete...

    Some background:

    Realativly old news. Any ID only chip without any cryptographic functions is stupidly
    easy to clone. Johnathan's device just proves how easy it is.

    Might want to checkout http://www.spychips.com/

      Needs more HMAC-driven challenge/response

        Problem is the limited computing power on the chip, limits the kinds of crypto that can be done. Usually what happens is some half-baked proprietary scheme gets used and eventually broken, as in the case of Exxon/Mobil Speedpass tags (http://www.rfidanalysis.org)

          I would think that if these devices are RF powered, the amount of power required to compute a secure challenge/response algorithm would be the biggest concern. But of course, the energy requirements ultimately limit the computing power which is of course the ultimate bottleneck in algorithm selection.
