 \section{The History of Tamper Sensing Meshes}
 
+Tamper-sensing meshes can be implemented in many different ways. Their design offers various degrees of freedom from the
+precise conductor layout, through the manufacturing technology of the mesh and how it is wrapped around the payload
+during manufacturing up to its monitoring circuitry. As a result, manufacturers across application domains from
+datacenter appliance HSMs through card payment terminals have historically used patents on parts of their tamper-sensing
+mesh implementations as a means to prevent copying of their designs~\cite{

+conductor to cover a surface traces back as far as at least 1870~\cite{
+    ImprovementProtectingSafes1870,
+    ImprovementElectromagneticEnvelopes1870}, when it was applied to the protection of bank vaults from robbers
+attempting to dig, drill and saw through the vault's floor and walls. Even multi-layer, orthogonal tamper-sensing meshes
+are documented as far back as 1902~\cite{suttonElectricallyprotectedStructure1902}. Using printed circuits instead of
+wires for this purpose occurs in literature as soon as printed circuit technology finds widespread commercial adoption
+in the 1960ies~\cite{hamPrintedcircuitTypeSecurity1971}. The history of more HSM-like devices begins in the 1990ies with
+the widespread adoption of cryptography in commercial applications~\cite{
