Looking at the landscape of computer security solutions, we are presented with a wide variety of vendors and products
that may give the impression that hardware security is a solved problem. Vendors sell various claims rangning from
\emph{``You don't need hardware security, just do it in the cloud!''}~\cite{

\textbf{Design Defects:}
\begin{itemize}
\item Incomplete mesh coverage
\item Meshes not overlapping at edges leaving gaps for probe insertion
\item Gaps at mesh-PCB interfaces
\item Thermoformed cavities with enlarged structure size at corners
\end{itemize}
\textbf{Obscurity Failures:}
\begin{itemize}
\item In one case, an opaque lacquer was easily removed with acetone (without damaging the mesh!)
\item Trace patterns visible through cover layers due to surface unevenness

abstract = {Germany is currently rolling out an opt-out, nation-scale database of the medical records of the majority of~its population, with low-income people being disproportionally represented among its users. While there has~been considerable criticism of the system coming from civil society, independent academic analysis of the system by~the cryptography and information security community has been largely absent. In this paper, we aim to raise awareness~of the systems existence and, based on the systems public specifications, highlight several concerning cryptographic engineering decisions. Our core observations is that the systems most sensitive long-term user keys are derived~by a rudimentary, home-grown centralized key escrow mechanism. This mechanism relies on a per-use salt and only 256~bit of entropy, shared globally across millions of users. Furthermore, the systems specification mandates only level~3 compliance with the obsolete FIPS 140-2 security standard, which requires “hard, opaque potting”, but lacks active tamper sensing. As a result, the system remains vulnerable to attacks by nation states and other well-funded adversaries.},
