In contrast to -traditional meshes, they use a large number of individual traces. Their concept promises a very high degree of -protection, but is limited in area covered and component height, as well as the high cost of the advanced analog -circuitry required for monitoring. A core component of their design is that they propose its use as a PUF to allow for -protection even when powered off, similar to a smart card---but the design is not limited to this use. +traditional meshes, they use a large number of individual traces (more than 30 in their example).

In~\cite{tobisch2020}, Tobisch et al.\ describe a construction technique for a hardware security module that is based on a WiFi transceiver inside a conductive enclosure. In their design, a reference signal is sent into the RF cavity formed |
