Abstract
An apparatus with an anti-tamper architecture includes a substrate and a layer of a pyrotechnic composite arranged on a surface of the substrate. The pyrotechnic composite includes a metal and a metal oxide, and the layer has a thickness of about 1 micrometer to about 10 millimeters. A reaction of the pyrotechnic composite is an exothermic reaction and at least partially fractures the substrate after the reaction is initiated.
