Abstract:
1. In a multilayered securing structure for the protection of cryptographic keys and codes contained therein from being compromised by external tampering, a method comprising the steps of: providing at least one of the layers of said multilayered securing structure with secure network circuits; contacting said secure network circuits with an electrically conductive material for obstructing tampering attempts to the secure network circuits, wherein the electrically conductive material obstructs tampering by being impervious to x-rays and the electrically conductive material obstructs tampering by destroying cryptographic information within secure cryptographic circuits when the electrically conductive material is damaged; and interfacing said electrically conductive material of said secure network circuits to the secure cryptographic circuits with apertures through said multilayered securing structure filled with a non solderable electrically conductive material, wherein said electrically conductive material comprises an electrically conductive constituent creating embedded resistive patterns distinct from and protective of said secure cryptographic circuits.
