+ \maketitle
+
+\section{The GNU Name System In a Nutshell}
+\begin{frame}{Motivation}
+ \begin{itemize}
+ \item DNS remains a source of traffic amplification DDoS.
+ \item DNS censorship (i.e. by China) causes collateral damage in other
countries.
+ \item DNS is part of the mass surveillance apparatus (MCB).
+ \item DNS is abused for offensive cyber war (QUANTUMDNS).
+ \item DoT/DoH, DNSSEC, DPRIVE unfortunately do \textbf{NOT} fix this.
+ \end{itemize}
+\end{frame}
+
+\begin{frame}{What is the GNU Name System?\footnote{Joint work with Christian
Grothoff and Matthias Wachs}}
+ \begin{itemize}
+ \item Fully decentralized name system $\Rightarrow$ Names are not global.
+ \item Supports globally unique and secure identification.
+ \item Features query and response privacy.
+ \item Provides a public key infrastructure
+ \begin{itemize}
+ \item Each zone is associated with a cryptographic key pair.
+ \item Delegation between zones establishes trust relationship.
+ \end{itemize}
+ \item Interoperable with DNS.
+ \item Usable.\footnote{User studies conducted in ``Decentralized
Authentication for Self-Sovereign Identities using Name Systems'' (DASEIN)
project.}
+ \end{itemize}
+\end{frame}
+
+\begin{frame}{Applications}
+ \begin{itemize}
+ \item Identity management: \textbf{re:claimID}
(\url{https://reclaim-identity.io})
+ \item Social Networks: \textbf{SecuShare} (\url{https://secushare.org})
+ \item Healthcare: \textbf{Accident insurance and private health
data}.\footnote{Joint work with FH Bern, ``Decentralized Authentication for
Self-Sovereign Identities using Name Systems'' (DASEIN)}
+ \item Others: \textbf{Chat}, \textbf{Host addressing}, \ldots
+ \end{itemize}
+\end{frame}
+
+\section{Technical Overview}
+\begin{frame}{Record Storage / Retrieval}
+ \begin{itemize}
+ \item GNS stores records in a \textbf{Distributed Hash Table} (DHT).
+ \item DHTs allow us to map keys to values.
+ \item Naive approach: Map domain names to records.\\e.g.: example.com
$\Rightarrow$ A: 1.2.3.4
+ \end{itemize}
+ \begin{center}
+ \includegraphics[width=0.5\textwidth]{DHT.pdf}
+ \end{center}
+\end{frame}
+
+%\begin{frame}{Record Storage / Retrieval}
+% \begin{itemize}
+% \item GNS implements a \textbf{Private Information Retrieval} (PIR)
scheme.
+% \item DHT values (records) are signed and encrypted.
+% \item DHT keys are derived from queried name and zone.
+% \end{itemize}
+% \begin{center}
+% \includegraphics[width=0.5\textwidth]{DHT.pdf}
+% \end{center}
+%\end{frame}
+
+\begin{frame}{Secure Storage / Retrieval}
+ \begin{itemize}
+ \item \textbf{Query privacy}
+ \begin{itemize}
+ \item GNS implements a \textbf{Private Information Retrieval} (PIR)
scheme:\\
+ ``a protocol that allows a user to retrieve an item from a server in
possession of a database without revealing which item is
retrieved.''\footnote{\url{https://en.wikipedia.org/wiki/Private_information_retrieval}}
+
+ \item Queries do not reveal domain name.
+ %item DHT keys are ``blinded'' record labels and zone identity.
+ \end{itemize}
+ \item \textbf{Record confidentiality}: Values in DHT are signed and
encrypted by zone owner.
+ \item \textbf{Zone privacy}: Zones cannot be enumerated.
+ \item \textbf{Censorship and DDoS resistance}: Decentralized, resilient
directory.
+ \end{itemize}
+\end{frame}
+
+\begin{frame}{Zone Delegation}
+ \begin{itemize}
+ \item The ``NS'' equivalent in GNS is called ``PKEY''.
+ \item A ``PKEY'' record contains public zone keys.
+ \item The combination of a ``PKEY'' record value and a name allows users to
+ query records in a delegated zone.
+ \end{itemize}
+\end{frame}
+

+\section{How do we bootstrap the top-level zones?}
+\begin{frame}
+ \includegraphics[height=0.9\textheight]{deleg3.pdf}
+\end{frame}
+
+
+\begin{frame}{The GNU Name System Root}
+ ``Hyper-hyper local root'' concept:
+ \begin{itemize}
+ \item Resolver ships with initial root zone configuration.
+ \item Root zone configurable \emph{locally} at \emph{each} endpoint.
+ \item User override/extension of root at top-level or subdomain-level for:
+ \begin{itemize}
+ \item Circumvent censorship if necessary.
+ \item Private networks.
+ \end{itemize}
+ \end{itemize}
+\end{frame}
+
+\begin{frame}{Envisioned Governance Model}
+ \begin{itemize}
+ \item Non-profit organization.
+ \item Multi-stakeholder model: Board, supporting organizations, \ldots
+ \item Examples for possible stakeholders:
+ \begin{itemize}
+ \item Software and OS Distributors
+ \item Browser vendors
+ \item Governments
+ \end{itemize}
+ \item Funding options:
+ \begin{itemize}
+ \item Applications for new top-level domains.
+ \item Registrations of new top-level domains.
+ \item \ldots
+ \end{itemize}
+ \end{itemize}
+\end{frame}
+
+
+\section{Quo Vadis?}
+\begin{frame}{Roadmap}
+ \begin{itemize}
+ \item In progress:
+ \begin{itemize}
+ \item 2019-2020: Technical specification of GNS protocol, packaging
and alternative implementations.\footnote{Funded by NLnet under EU Next
Generation Internet program (\url{https://nlnet.nl/project/GNS/}).}
+ \item Continuous development and integration into applications.
+ \end{itemize}
+ \item 2020--: Establishment of governing body.
