To motivate our research, we showed on the German national digital health record +system how hardware security is hard to achieve in practice. Besides some minor cryptographic oddities, our analysis +revealed at least one essential specification mistake that negates the hardware security of the system by unnecessarily +introducing a poorly protected HSM. In the following chapters, we first introduced IHSM technology, then provided deep +analyses of two of its engineering challenges, mesh monitoring and power transfer. We propose a low-cost TDR-based mesh +monitoring system that exceeds the capabilities of all previous systems from academic or from patent literature by +monitoring large meshes while simultaneously providing detailed results. Our TDR-based mesh monitoring system is of +independent interest, since it can also be integrated into traditional HSM designs. Besides improved mesh monitoring, we +also proposed a new, generalized design for high-frequency PCB inductors with low parasitic capacitance. Our design +provides better bandwidth and lower parasitic capacitance compared to the state of the art without increasing +implementation cost. We concluded our thesis with two chapters elaborating on two new use cases that are made possible +by IHSM technology due to its ability to protect large payloads that have high power consumption. +We believe that with the research presented in this thesis, we substantially advanced the physical security field. In +particular, we belive that by publishing our research including its artifacts under open-source licenses, we provide the +basis for future research in tamper-sensing technology, a field that remains under-served in today's academic landscape.
