Zusammenfassung:A conductor on glass security layer may be located within a printed circuit board (PCB) of a crypto adapter card or within a daughter card upon the crypto adapter card. The conductor on glass security layer includes a glass dielectric layer that remains intact in the absence of point force loading and shatters when a point load punctures or otherwise contacts the glass dielectric layer. The conductor on glass security layer also includes a conductive security trace upon the glass dielectric layer. A physical access attempt shatters a majority of the glass dielectric layer, which in turn fractures the security trace. A monitoring circuit that monitors the resistance of the conductive security trace detects the resultant open circuit or change in security trace resistance and initiates a tamper signal that which may be received by one or more computer system devices to respond to the unauthorized attempt of physical access.
