-
-Paper abstract
---------------
-
-    Security Meshes are patterns of sensing traces covering an area that are used in Hardware Security Modules (HSMs)
-    and other systems to detect attempts to physically intrude into the device's protective shell. State-of-the-art
-    solutions manufacture meshes in bespoke processes from carefully chosen materials, which is expensive and makes
-    replication challenging. Additionally, state-of-the-art monitoring circuits sacrifice either monitoring precision or
-    cost efficiency. In this paper, we present an embeddable security mesh monitoring circuit constructed from low-cost,
-    standard components that utilizes Time Domain Reflectometry (TDR) to create a unique fingerprint of a mesh. Our
-    approach is both low-cost and precise, and enables the use of inexpensive standard Printed Circuit Boards (PCBs) as
-    security mesh material. We demonstrate a working prototype of our TDR circuit costing less than 10 € in components
-    that achieves both time resolution and rise time better than 200 ps—a 25 × improvement over previous work. We
-    demonstrate a simple classifier that detects several types of advanced attacks such as probing using an oscilloscope
-    probe or micro-soldering attacks with no false negatives.
-
-Repo structure
---------------
-
-``main_pcb``
-    KiCad design files, exports and manufacturing files for the main circuit board. This board contains the measurement
-    circuit, and has a connector for test coupons to be inserted. Data is read out throught the SWD interface using an
-    SWD adapter. The board is a 6-layer PCB. The circuit is described in detail in the paper. It is based around a
-    ``STM32G474RE`` ARM microcontroller.
-
-``test_coupons``
-    KiCad design files, exports and manufacturing files for the test coupon PCBs. The coupons are four-layer boards.
-    Each coupon contains four test meshes, two on each side, that can be connected through four SFP form factor board
-    edge connectors at the coupon's corners.
-
-``firmware``
-    Source code for the board firmware as well as tooling for running the experiments. The firmware is written in C, and
-    you'll need a standard ARM GCC/binutils toolchain to build it. The experiment tool is a python script that connects
-    to the board through GDB and exposes a local web server for controlling the board, monitoring the measurements in
-    real time, and capturing data.
-
-``analysis``
-    All raw data, as well as the Jupyter notebooks used for analysis and plotting. By running these notebooks, you can
-    re-run the analysis, and re-export all plots in the paper. The raw data is contained in JSON files, one per
-    measurement series. Each JSON file contains some metadata describing the experiment and the settings used during the
-    experiment, a set of calibration runs with the target specimen disconnected using the board's routing switches, and
-    a full set of 12 measurement arrays consisting of a mean and standard deviation for each data point. To save space,
-    batches of these JSON files are aggregated into zip archives. The analysis Jupyter notebooks will automatically load
-    and decode the data from these zip archives when run.
-
-``paper``
-    The source of the paper, as well as exports of all plots.
-
-Running the analysis
---------------------
-
-To re-run the analysis, first install `Jupyter Lab <https://jupyter.org/>`__ and the `numpy <https://numpy.org/>`__ and
-`scipy <https://scipy.org/>`__ python packages. If you're running in a virtualenv or on a weird platform like Windows or
-MacOS, make sure that jupyter and pip agree where your python lives and the packages get installed in the right place.
-
-Afterwards, just run ``jupyter lab`` in the ``analysis/jupyter_notebooks`` directory. You can then open any of the
-notebooks through the left side panel and re-run the analysis within. Make sure you run all of the setup code at the top
-of the notebook once before trying to run the analaysis code in the cells below. The analysis code only uses standard
-scientific python packages that you probably already have installed. If you get an ``ImportError``, make sure the
-packages listed in the file ``analysis/jupyter_notebooks/requirements.txt`` are installed.
-
-The notebooks will display the plots and results inside Jupyter Lab and will also automatically export the plots to the
-``paper`` directory of your clone of the git repository.
-
-PCB Designs
------------
-
-This repo includes both the raw CAD files of the PCBs, as well as exported manufacturing data for easier viewing if you
-don't have KiCad installed. The schematics are included as PDF exports.
-
-The PCB designs were prepared in the open source KiCad_ EDA tool. Note that for some files you might need to download a
-KiCad nightly build depending on how new your KiCad version is.
-
-PCB design folder structure
-...........................
-
-``foobar.{kicad_pro,kicad_sch,kicad_pcb,etc.}``
-    The KiCad source files of the PCB. Open the ``.kicad_pro`` file in KiCad, then you can open the schematics and board
-    layout from there.
-
-``fab/gerbers.zip``
-    Gerber exports of the board layouts. You can open these in any Gerber viewer such as gerbv_. These files are
-    essentially vector graphics exports of the board layout. They show what copper, silkscreen etc. you see on the
-    board, but they don't include any semantic information such as component values. You can send this zip directly to a
-    PCB manufacturer and they will be able to manufacture these boards for you. The order parameters are included in the
-    gerber files on the ``User.Comments`` layer.
-
-``fab/{bom.csv,pos.csv}``
-    Bill of materials and component placement coordinate files for board manufacturing. If you want a contract
-    manufacturer to solder these boards for you, you need to give them these two files in addition to the gerbers. The
-    BOM tells them what exact parts and how many of them you need, the position file tells them where to put them on the
-    board. We had JLCPCB make the PCBs, and we also had them solder most of the parts. Some parts we soldered after the
-    fact by hand because JLC didn't have them in stock, and getting them to order and solder them for us would have been
-    pretty expensive.
-
-    If you want to solder the main PCB yourself, you need some prior experience in fine SMD work and a decently setup
-    electronics lab with a microscope, a hot air reworks station, etc.
-
-    Note: **The PCB revision here does not have a functional driver IC!** For our lab experiments we microsoldered
-    the four different driver ICs by hand to avoid having to spin multiple copies of this expensive PCB. For some basic
-    measurements, you can just omit the driver IC included in the design and bridge it. This will drive the mesh
-    directly from the ``74LVC2G157`` gates, which is enough for some basic measurements.
-
-``schematics/*.pdf``
-    PDF export of the schematics of the board.
-
-Firmware
---------
-
-The firmware and associated scripts are contained in the ``firmware`` directory.
-
-Building the firmware
-.....................
-
-If you have an ARM GCC toolchain installed, you can build the firmware by running ``make`` in this directory. During
-build, the makefile exports some diagnostic information about the build artifacts. For that to work, you have to have
-the `cxxfilt python package <https://pypi.org/project/cxxfilt/>`__ installed. If the package can't be found, the
-firmware will still be built, but you will get a crash in the makefile during the analysis step that runs after the
-build was successful.
-
-Running experiments
-...................
-
-To run an experiment, you need a measurement board and a test coupon. You also need the following software installed on
-your machine:
-
-* ``openocd``
-* ``arm-none-eabi-gdb`` (another ABI arm gdb should work too)
-* The python packages listed in ``firmware/requirements.txt``
-
-To build the firmware, you additionally need a ARM toolchain installed. By default, the makefile assumes gcc/gnu
-binutils, but you can override that if you prefer to use LLVM.
-
-To run an experiment, connect the board to power via USB, and to your computer through an SWD debug adapter. We used
-cheap STLinkV2 clones, if you have a different adapter you'll have to modify the ``.gdbinit`` script accordingly. After
-connecting the board, open three terminal windows running the following three commands one per window, in this order.
-
-1. ``openocd -f openocd.cfg``
-2. ``arm-none-eabi-gdb build/main.elf``
-3. ``python adc_serve.py``
-
-This will connect to the board and start the realtime control and measurement web interface. You can open the web
-interface at the location printed by ``adc_serve.py`` on startup.
-
-If you're cheap like us and use a STLinkV2 clone SWD adapter, it may be that openocd takes a few (maybe up to five or
-so) attempts to start up and connect to the microcontroller. After starting, the GDB terminal should start printing a
-few lines of output every 30 seconds or so when it saves a measurement series. If GDB starts to hang, it might be that
-you bumped a cable or accidentially shorted something on the board. To re-start, you first kill gdb (Ctrl+C, then
-Ctrl+D, then Ctrl+D again), then you stop openocd (Ctrl+C, kill it if it doesn't stop in a few seconds), then you
-restart them in the order above. You don't have to restart the web interface, just adjust any of the knobs to overwrite
-the default control settings again.
-
-Firmware Folder Structure
-.........................
-
-``src/main.c``
-    The source code of the mainboard firmware. This firmware captures data into internal buffers, which are read out
-    from the host through SWD.
-
-``openocd.cfg``
-    OpenOCD script for connecting to the debug adapter. We used cheap STLinkV2 clones from aliexpress. If you use a
-    different debug adapter, you will have to modify this file accordingly to tell OpenOCD how to connect to the board.
-    The port numbers given here and in the ``.gdbinit`` must match up.
-
-``.gdbinit``
-    GDB script running the data extraction. This script will continuously dump the measurement data into ``/tmp`` every
-    time a measurement series has been completed. Note that this file will be hidden on unixes. Also note that you will
-    have to explicitly allowlist this file's absolute path on your computer in your ``$HOME/.gdbinit`` the first time
-    you run it because gdb refuses to run unknown ``.gdbinit`` files for security.
-
-``adc_serve.py``
-    Real-time monitoring and data capture tool. Before running this, first make sure you have gdb attached to the board
-    using the ``.gdbinit``. The tool communicates with the gdb script through files in ``/tmp``. It exposes a web
-    interface that displays the captured data in real time, allows you to change the board's measurement settings, and
-    allows you to export measurement series.
-
-``make_barcodes.py``
-    This is a helper script we used to create barcode labels for all ~120 test specimens to simplify the measurement
-    workflow. We had a barcode reader hooked up to the computer running the measurements, so you could just scan a
-    specimen's barcode to capture a data series registered to that board in the web interface.

-    Build files for the firmware. These are mostly generic to this type of microcontroller and are included here so the
-    firmware source is self-contained.
