    Abstract: 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.

    Abstract: An optical electromagnetic radiation (EM) emitter and receiver are located upon a printed circuit board (PCB) layer and are connected to an optical security pathway. A predetermined reference flux is determined, the reference flux being the expected EM transmitted by the optical security pathway and received by the receiver. When the PCB is subject to an unauthorized access thereof (e.g., drilled, sawed, cut, etc.), the optical EM transferred by optical security pathway is altered. An optical monitoring device that monitors the flux of the optical EM received by the receiver detects a change in flux, in relation to the reference flux, and passes a tamper signal to one or more computer system devices to respond to the unauthorized access. For example, one or more cryptographic adapter card or computer system functions or secured crypto components may be disabled.
