Device for protecting electronic circuits from unauthorized access
TLDR
In this paper, the authors proposed a cover element that is made of a material that is very hard and at the same time very brittle, which can be connected to a detection circuit to detect mechanical damage.Abstract:
To improve a device for protecting electronic circuits from unauthorized access so that it can be produced inexpensively, can be handled and guarantees increased security, the invention proposes a device for protecting electronic circuits from unauthorized access with at least one hood-type cover element, which is arranged on a circuit plate covering it at least in some areas and has tracks that can be connected to a detection circuit to detect mechanical damage, wherein the cover element is made of a material that is very hard and at the same time very brittle.read more
