% Related Work in Intro nach vorne
% Im Abstact kurz auf related work eingehen.
% Related work: Bullets zu lang
% Bullet-Listen sind uneven
% Capacitive PUFs: bei Limitaitons zitieren, welche der Arbeiten gemeint ist.
% Bei Diss-Citations in der bib dazu schreiben, dass das ne Diss ist.
% 2.2 / 2.3 Wie related? Warum interessant? In Intro erwähnen?

Security meshes continue to be the state of the art for tamper sensing in in applications where sophisticated physical
attacks such as attempts at drilling or sawing through the device's enclosure to place probes must be prevented. Common
applications for such meshes include Hardware Security Modules (HSMs) used to store and process cryptographic keys while
applying certain security standards such as
FIPS-140-2\cite{usnationalinstituteofstandardsandtechnologySecurityRequirementsCryptographic2002} or ISO/IEC
24759\cite{ISOIEC24759}, as well as card payment terminals where PCI PTS HSM
24759\cite{ISOIEC24759}. Other applications include as card payment terminals where PCI PTS HSM
standards\cite{pcisecuritystandardscouncilPaymentCardIndustry2021} are applicable. Security meshes usually consist of
two or more conductive traces that are laid out in a meandering pattern to cover a surface, and which are monitored
electrically to detect attempts at penetrating this surface. While commercial designs often only monitor for short
circuits or breaks in the mesh traces, monitoring this coarse is incapable of detecting even less sophisticated attacks
attempting to circumvent part of the mesh, thus requring the mesh to be made from a special material that is difficult
to manipulate without breaking it.

breaks in the mesh traces and are incapable of detecting attacks that circumvent part of the mesh, thus requring the
mesh to be made from a special material that is difficult to manipulate without breaking it. Cretaing such meshes
is expensive and requires specialized technology.
To enable the use of less expensive, commodity materials such as Printed Circuit Boards (PCBs), mesh integrity must be
monitored with higher fidelity. In this paper, we present a low-cost monitoring circuit for security meshes based on a
