tamper-sensing mesh of a conventional HSM is replaced by a mesh made from simple PCBs that is rotating at high speed
|

around the payload. Since the mesh is rotating at high speed, it cannot be manipulated, and the security of conventional

meshes created in bespoke manufacturing processes can be achieved using much simpler and less expensive construction
|

techniques. We present the results of a survey of approximately 30 real world tamper sensing mesh implementations. We

deduce design criteria for secure meshes and contextualize our design. We further motivate the necessity of secure

hardware by presenting an analysis of problematic aspects in the hardware security design of Germany's new national

To pave the way for practical implementations of IHSM technology, we present solutions to key engineering challenges in
|
||||
IHSM construction. We present a design and analysis of highly symmetric planar inductors for rotating wireless power
|
||||
transfer that improves self-resonant frequency by up to \qty{58}{\percent} and inductance by up to \qty{6.5}{\percent}
|
||||
in our tests. We present a high-fidelity, low-cost monitoring system for security meshes that is based on the principles
|
||||
of Time-Domain Reflectometry (TDR), reaching \qty{184}{\pico\second} time resolution. We validate our system and find
|
||||
that it is able to reliably detect several classes of advanced physical attacks. We find that our system is sensitive
|
||||
enough to detect differences between identical copies of the same mesh, suggesting PUF-like properties.

Applying IHSM technology, we analyse two use cases that are unlocked by the increased size and power dissipation

capability of IHSMs. In the first analysis, an IHSM-secured relay node for Quantum Key Distribution (QKD) systems is
