+\section{Introduction}
+
+Widely used primitives like the AES~\cite{AES} do not have perfect
+security, and can be analysed with linear
+cryptanalysis~\cite{EC:Matsui93}, differential
+cryptanalysis~\cite{JC:BihSha91}, or differential power
+analysis~\cite{C:KocJafJun99}.  We show that the One-Time-Pad is
+unconditionally secure in \autoref{sec:main}. Let's not forget
+the work by John~\cite{vonNeumann}.
+
+Note that we can tolerate ampersands~\cite{Dalheimer02} and \TeX
+character codes~\cite{Bohme10} and math in
+title~\cite{ACISP:MurPla19,ACISP:LYLF19,ACISP:WeiSteSha03,CCS:BHKNRS19,ACNS:DurHugVau20}.
