+Creative Commons Legal Code
+
+CC0 1.0 Universal
+
+    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
+    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
+    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+    HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+    surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+    warranties of any kind concerning the Work, express, implied,
+    statutory or otherwise, including without limitation warranties of
+    title, merchantability, fitness for a particular purpose, non
+    infringement, or the absence of latent or other defects, accuracy, or
+    the present or absence of errors, whether or not discoverable, all to
+    the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+    that may apply to the Work or any use thereof, including without
+    limitation any person's Copyright and Related Rights in the Work.
+    Further, Affirmer disclaims responsibility for obtaining any necessary
+    consents, permissions or other rights required for any use of the
+    Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+    party to this document and has no duty or obligation with respect to
+    this CC0 or use of the Work.

+\maketitle
+
+% use optional argument because the \LaTeX command breaks the PDF keywords
+\keywords[\publname, TCHES, LaTeX]{\publname \and TCHES \and \LaTeX}
+
+\begin{abstract}
+  This document is a quick introduction to the \LaTeX{} class for the
+  \publname{}.
+\end{abstract}
+
+\section*{Introduction}
+
+The \texttt{iacrtans} \LaTeX{} class will be used by the new
+``\publname'' journal.  The class is based on standard \LaTeX{}
+classes and packages (mainly the \texttt{article} class with
+\texttt{amsmath}), and should be similar in use to the \texttt{llncs}
+class used for Springer's proceedings.  The \LaTeX{} source of this
+documentation is meant as an example to show basic usage of the class.
+
+Since we are now preparing the zero-th issue of the journal, the class
+is still in development and feedback and comments are welcome.
+
+\subsection*{\textcolor{red!70!black}{FAQ:} Converting \texttt{llncs} papers to \texttt{iacrtrans}}
+
+If you have a paper typeset with the \texttt{llncs} class, conversion
+should be relatively easy.  The following steps should be sufficient
+in most cases (for the submission version):
+\begin{enumerate}
+\item Replace \verb+\documentclass{llncs}+ with\\ \verb+\documentclass[submission,spthm]{iacrtrans}+;
+\item Replace \verb+\bibliographystyle{splncs03}+ with
+  \verb+\bibliographystyle{alpha}+;
+\item Add a \verb+\keywords{}+ command before the abstract, with
+  keywords separated by \verb+\and+;
+\item Remove commands that might override the class style, such as
+  \verb+\pagestyle{...}+ or \verb+\thispagestyle{...}+,
+  change of margins (\emph{e.g.}  with the \texttt{geometry} package),
+  change of fonts, ....
+\item See also \autoref{sec:biblio} for information about how to
+  typeset the bibliography.
+\end{enumerate}
+
+\section{Main Commands}
+
+\subsection{Title page}
+
+The following commands are used to input informations for the title page.
+
+\paragraph{\texttt{\textbackslash title}} to define the title.
+
+A shorter running title can be given as optional argument.
+
+\paragraph{\texttt{\textbackslash subtitle}} to give an optional
+subtitle.
+
+\paragraph{\texttt{\textbackslash author}} to define the author list.
+
+Author names must be delimited by \verb+\and+ macros.  If there is one
+different affiliation for each author, authors and affiliations will be
+numbered automatically.  Otherwise, each author name must be followed by
+\verb+\inst{...}+ with the corresponding affiliation(s).
+
+A shorter list of authors for the running head can be given as
+optional argument.
+
+\paragraph{\texttt{\textbackslash institute}} to give author's affiliation(s).
+
+If there are several affiliations, they must be separated by
+\verb+\and+ macros, and will be numbered automatically.
+
+\paragraph{\texttt{\textbackslash keywords}} to give a list of
+keywords.
+
+Individual keywords should be separated by the \verb+\and+ macro.
+
+If there are fragile commands in the keywords, use the optional argument
+to give a text-only version of the keywords; this will be used for the
+PDF meta-data.
+
+\paragraph{\texttt{\textbackslash email}} should be used inside the
+\verb+\institute+ argument to typeset author's email address(es).  An
+optional argument can be given for the hyperlink, if different from the
+displayed email.  For instance, you can group emails as follows:\\
+\verb+\email[alice@foo.com,bob@bob.com]{{alice,bob}@foo.com}+
+
+\paragraph{\texttt{\textbackslash thanks}}
+can be used inside the \verb+\title+,
+\verb+\author+ or \verb+\institute+ argument to generate a footnote with additional
+information, if needed.
+
+\paragraph{\texttt{\textbackslash maketitle}} is used to actually
+typeset the title.
+
+\paragraph{The \texttt{abstract} environment} should be used to typeset the abstract.
+
+Note that the keywords should be given before starting the abstract environment.
+
+
+\subsection{Theorems}
+
+The \texttt{iacrtrans} class uses the \AmS{} packages to typeset
+math.  In particular, it loads the \texttt{amsthm} package, and
+predefines the following environments:
+\begin{center}
+  \ttfamily
+\begin{tabular}{l@{\hspace{1cm}}l@{\hspace{1cm}}l}
+theorem     & definition & remark \\
+proposition & example    & note   \\
+problem     & exercise   & case   \\
+lemma       & property   &        \\
+conjecture  & question   &        \\
+corollary   & solution   &        \\
+claim       &            &        \\
+\end{tabular}
+\end{center}
+
+Note that the \texttt{proof} environment automatically adds a QED
+symbol at the end of the proof (unless you give option
+\texttt{[spthm]} to the \texttt{iacrtrans} class).  If the QED symbol
+is typeset at a wrong position, you can force its position with
+\verb+\qedhere+.
+
+\section{Class options}
+\label{sec:options}
+
+\subsection{Publication type}
+
+The class supports four publication types, selected with the
+following class options:
+
+\begin{description}
+\item[\texttt{[final]}] for final papers (default mode)
+\item[\texttt{[preprint]}] for preprints (without copyright info)
+\item[\texttt{[submission]}] for submissions (anonymous, with line numbers)
+\item[\texttt{[draft]}] is similar to preprint, but activates draft
+  mode for the underlying \texttt{article} class (which shows overfull hboxes), and other packages
+  (\emph{e.g.} \texttt{graphicx}, \texttt{hyperref}).
+\end{description}
+
+\subsection{Other Options}
+
+\paragraph{\texttt{[spthm]}}
+provides theorem environments that emulates
+\texttt{llncs} class's \texttt{sptheorem}:
+\begin{itemize}
+\item A \texttt{\textbackslash spnewtheorem} wrapper is provided
+  around \AmS{} \texttt{\textbackslash newtheorem}.  Note that the
+  styling options are ignored; you should use standard
+  \texttt{amsthm} commands for fine control.
+\item The \AmS{} \texttt{proof} environment will not automatically add a
+  QED symbol at the end of the proof.
+\end{itemize}
+
+\paragraph{\texttt{[floatrow]}}
+uses the \texttt{floatrow} package to customize floats rather than the
+plain \texttt{float} package.  In particular, this allows to typeset
+floats side by side as shown in this example:
+\begin{verbatim}
+\documentclass[floatrow]{iacrtrans}
+\usepackage[demo]{graphicx}
+\begin{document}
+
+\begin{figure}
+  \begin{floatrow}
+    \ffigbox{\includegraphics[width=0.4\textwidth]{1.png}}
+    {\caption{This is caption 1.}}
+    \ffigbox{\includegraphics[width=0.4\textwidth]{2.png}}
+    {\caption{This is caption 2.}}
+  \end{floatrow}
+\end{figure}
+
+\end{document}
+\end{verbatim}
+
+The row will be divided equally according to the number of figures, but
+you can ask each figure to take its natural space instead with
+\verb+\ffigbox[\FBwidth]+.  For more advanced use, see the
+\texttt{floatrow} documentation.
+
+
+\paragraph{\texttt{[nohyperref]}}
+disables the automatic loading of
+\texttt{hyperref}.  Use this is if your document fails to compile with
+\texttt{hyperref} for some reason.
+
+The \texttt{iacrtrans} class automatically loads \texttt{hyperref}
+after all other packages.  If you need some packages to be loaded
+\emph{after} \texttt{hyperref}, you should load \texttt{hyperref}
+explicitly at the correct position, but not use the \texttt{[nohyperref]} option.
+
+\section{Typesetting the Bibliography}
+\label{sec:biblio}
+
+% Borrowed from btxdoc.tex
+\def\BibTeX{{\rm B\kern-.05em{\sc i\kern-.025em b}\kern-.08em
+    T\kern-.1667em\lower.7ex\hbox{E}\kern-.125emX}}
+
+Having good bibliographic references is very important for the
+visibility of the journal.  Since we don't have a commercial editor,
+authors need to make sure themselves that references are standardized
+and clean.  We strongly encourage authors to use \BibTeX{} for the
+bibliograpy, using bibliographic data
+from \url{http://www.dblp.org} or \url{https://cryptobib.di.ens.fr/}.
+
+We are still working on a good solution for the bibliography, and we
+expect to have more specific instructions when producing the final
+version of the papers, including a dedicated \BibTeX{} style.
+
+
+\section{Further instructions}
+
+\paragraph{\LaTeX{} distribution, and worklow.}  \LaTeX{}
+distributions are available on a variaty of platforms.  In particular,
+we recommand the \href{https://www.tug.org/texlive/}{TeX Live}
+distribution, which is updated regularly, include a large number of
+packages, and is available on many platforms.
+\begin{description}
+\item[Linux:] A LaTeX installation is included in most Linux
+  distributions.  Alternatively,
+  \href{https://www.tug.org/texlive/}{TeX Live} can be installed
+  easily without root access.
+\item[Windows:] There are also good \LaTeX{} distributions for Windows,
+  such as \href{http://www.miktex.org/}{MikTeX} and
+  \href{https://www.tug.org/texlive/}{TeX Live}.
+\item[MacOSX:] On MacOSX, TeX Live is available inside
+  \href{http://www.tug.org/mactex/}{MacTeX}.
+\end{description}
+
+
+We recommand the use of \texttt{pdflatex} because it generally
+supports more features than \texttt{latex} and \texttt{dvips}
+(\texttt{xelatex} and \texttt{lualatex} are also missing some advanced
+features from \texttt{pdflatex}).
+
+\paragraph{Internal references.}
+
+We recommend the use of \verb+\autoref+ from \texttt{hyperref}
+(automatically loaded by the class).  For instance,
+\verb+\autoref{sec:options}+ links to \autoref{sec:options}.
+
+\paragraph{Pictures.}
+
+We recommend the use of the \texttt{tikz} package to render pictures.
+
+In particular, a large variety of crypto pictures made with
+\texttt{tikz} is available at \url{http://www.iacr.org/authors/tikz/}.
+
+\paragraph{External pictures.}  The \texttt{graphicx} is loaded by the
+class, and is recommended for external figures.
+
+If possible, external figures should be in a vector format: you can
+use PDF files when compiling with \texttt{pdflatex}, and EPS files
+when compiling with \texttt{latex}, and \texttt{dvips}.  Note that the
+\verb+\includegraphics+ command will automatically select a file with
+the right extension, so if you write \verb+\includegraphics{figure}+
+and have two files \texttt{figure.pdf} and \texttt{figure.eps}, it
+should work with both workflow.
+
+\paragraph{Floats.}
+
+Figure captions should be below the figures, and table captions above
+the tables.  The \texttt{float} package loaded by the class should
+take care of this automatically.  If want to have several figures side
+by side, see the \texttt{[floatrow]} option.
+
+\paragraph{Tables.}
+
+We recommend the \texttt{booktabs} package to typeset tables.
+
+\paragraph{Algorithms.}
+
+We recommend the \texttt{algorithm}, \texttt{algorithmcx} packages for
+algorithms (in particular, \texttt{algpseudocode} for pseudo-code).
+
+
+\section{For the Editor}
+
+The following commands should be used by the editor to prepare the final
+version:
+
+\paragraph{\texttt{\textbackslash setfirstpage}} to set the first page number.
+
+\paragraph{\texttt{\textbackslash setlastpage}} to set the first page
+number (optional).
+
+\paragraph{\texttt{\textbackslash setvolume}} to set the volume number.
+
+\paragraph{\texttt{\textbackslash setnumber}} to set the edition number.
+
+\paragraph{\texttt{\textbackslash setDOI}} to set the DOI.
+
+
+\section{Further information}
+
+More general information can be found in the following documents:
+\begin{itemize}
+\item General \LaTeX{} documentation, such as the
+  \href{http://mirrors.ctan.org/info/lshort/english/lshort.pdf}{(not
+    so) short introduction to \LaTeXe};
+% \item The \texttt{article} class
+%   \href{http://mirrors.ctan.org/macros/latex/doc/clsguide.pdf}{documentation};
+\item The \AmS-\LaTeX{}
+  \href{http://mirrors.ctan.org/macros/latex/required/amslatex/math/amsldoc.pdf}{documentation}
+  and \texttt{amsthm} \href{ftp://ftp.ams.org/pub/tex/doc/amscls/amsthdoc.pdf}{documentation};
+\item Documentation of the \LaTeX{} packages used in the class (see below).
+\end{itemize}
+
+\subsection{Packages used}
+
+The class is based on the standard \texttt{article} class, and loads
+the following packages:
+\begin{itemize}
+\item \texttt{geometry}, \texttt{secsty}, \texttt{fancyhdr}, \texttt{mathtools},
+  \texttt{float}, \texttt{microtype}, \texttt{lastpage}
+\item \texttt{amsmath}, \texttt{amssymb}, \texttt{amsthm}
+\item \texttt{graphicx}
+\item \texttt{hyperref}, \texttt{hyperxmp}, \texttt{etoolbox}, \texttt{xcolor} (unless
+  the \texttt{[nohyperref]} option is used)
+\item \texttt{lineno} (in \texttt{[submission]} mode)
+\item \texttt{floatrow,caption} (with option \texttt{[floatrow]})
+\end{itemize}
+
+\section*{Thanks}
+
+We would like to thank people who helped design and improve the
+class:
+Anne Canteaut,
+Jérémy Jean,
+Bart Preneel,
+Christian Rechberger,
+Tyge Tiessen,
+Friedrich Wiemer.
+

+\section{Introduction}
+
+In the power grid, as in many other engineered systems, we can observe an ongoing diffusion of information systems into
+industrial control systems. Automation of these control systems has already been practiced for the better part of a
+century.  Throughout the 20th century this automation was mostly limited to core components of the grid. Generators in
+power stations are computer-controlled according to electromechanical and economic models. Switching in substations is
+automated to allow for fast failure recovery. Human operators are still vital to these systems, but their tasks have
+shifted from pure operation to engineering, maintenance and surveillance\cite{crastan03,anderson02}.
+
+With the turn of the century came a large-scale trend in power systems to move from a model of centralized generation,
+built around massive large-scale fossil and nuclear power plants, towards a more heterogenous model of smaller-scale
+generators working together. In this new model large-scale fossil power plants still serve a major role, but two new
+factors come into play. One is the advance of renewable energies. The large-scale use of wind and solar power in
+particular from a current standpoint seems unavoidable for our continued existence on this planet. For the electrical
+grid these systems constitute a significant challenge. Fossil-fueled power plants can be controlled in a precise and
+quick way to match energy consumption. This tracking of consumption with production is vital to the stability of the
+grid. Renewable energies such as wind and solar power do not provide the same degree of controllability, and they
+introduce a larger degree of uncertainty due to the unpredictability of the forces of nature\cite{crastan03}.
+
+Along with this change in dynamic behavior, renewable energies have brought forth the advance of distributed generation.
+In distributed generation end-customers that previously only consumed energy have started to feed energy into the grid
+from small solar installations on their property. Distributed generation is a chance for customers to gain autonomy and
+shift from a purely passive role to being active participants of the electricity market\cite{crastan03}.
+
+To match this new landscape of decentralized generation and unpredictable renewable resources the utility industry has
+had to adapt itself in major ways. One aspect of this adaptation that is particularly visible to ordinary people is the
+computerization of end-user energy metering. Despite the widespread use of industrial control systems inside the
+electrical grid and the far-reaching diffusion of computers into people's everyday lives the energy meter has long been
+one of the last remnants of an offline, analog time. Until the 2010s many households were still served through
+electromechanical Ferraris-style meters that have their origin in the late 19th
+century\cite{borlase01,ukgov04,bnetza02}.  Today under the umbrella term \emph{Smart Metering} the shift towards fully
+computerized, often networked meters is well underway. The roll out of these \emph{Smart Meters} has not been very
+smooth overall with some countries severely lagging behind. As a safety-critical technology, smart metering technology
+is usually standardized on a per-country basis. This leads to an inhomogenous landscape with--in some instances--wildly
+incompatible systems.  Often vendors only serve a single country or have separate models of a meter for each country.
+This complex standardization landscape and market situation has led to a proliferation of highly complex, custom-coded
+microcontroller firmware. The complexity and scale of this--often network-connected--firmware makes for a ripe substrate
+for bugs to surface.
+
+A remotely exploitable flaw inside a smart meter's firmware\footnote{
+    There are several smart metering architectures that ascribe different roles to the component called \emph{smart
+    meter}. Not all systems are susceptible to attacks to the same degree, with the German implementation being almost
+    immune as far as energy availability is concerned. For clarity, we use \emph{smart meter} to describe the entire
+    system at the customer premises including both the meter and if present a gateway.
+} could have consequences ranging from impaired billing functionality to an existential threat to grid
+stability\cite{anderson01,anderson02}. In a country where meters commonly include disconnect switches for purposes such
+as prepaid tariffs a coördinated attack could at worst cause widespread activation of grid safety systems by repeatedly
+connecting and disconnecting megawatts of load capacity in just the wrong moments\cite{wu01}.
+
+Mitigation of these attacks through firmware security measures is unlikely to yield satisfactory results. The enormous
+complexity of smart meter firmware makes firmware security extremely labor-intensive. The diverse standardization
+landscape makes a coördinated, comprehensive response unlikely.
+
+In this paper, instead of focusing on the very hard task of improving firmware security we introduce a pragmatic
+solution to the--in our opinion likely--scenario of a large-scale compromise of smart meter firmware. In our proposal
+the components of the smart meter that are threatened by remote compromise are equipped with a physically separate
+\emph{safety reset controller} that listens for a reset command transmitted through the electrical grid's frequency and
+on reception forcibly resets the smart meter's entire firmware to a known-good state.  Our safety reset controller
+receives commands through Direct Sequence Spread Spectrum (DSSS) modulation carried out on grid frequency through a
+large controllable load such as an aluminum smelter. After forward error correction and cryptographic verification it
+re-flashes the meter's main microcontroller over the standard JTAG interface.  Note that our modulation technique is one
+\emph{changing grid frequency itself}.  This is fundamentally different in both generation and detection from systems
+such as traditional PLC that superimpose a signal on grid voltage, but leave grid frequency itself unaffected.
+
+In this thesis, starting from a high level architecture we have carried out extensive simulations of our proposal's
+performance under real-world conditions. Based on these simulations we implemented an end-to-end prototype of our
+proposed safety reset controller as part of a realistic smart meter demonstrator. Finally we experimentally validated
+our results and we will conclude with an outline of further steps towards a practical implementation.
+
+This work contains the following contributions:
+\begin{enumerate}
+    \item We introduce Grid Frequency Modulation (GFM) as a communication primitive. % FIXME done before in that one paper
+    \item We elaborate the fundamental physics underlying GFM and theorize on the constrains of a practical
+        implementation.
+    \item We design a communication system based on GFM.
+    \item We carry out extensive simulations of our systems to determine its performance characteristics.
+    \item We show the simple grid voltage recorder design we used to capture data for our simulations.
+    \item We introduce a new, simplified method to determine grid frequency from a capture of the grid voltage waveform
+        that is simple to implement on constrained embedded devices.
