Abstract:
1. A security module for protecting circuit components from unauthorized access, the module comprising: a substrate composed of a plurality of layers including a first layer, the first layer of the substrate for supporting circuit components to be protected; a cover member having side portions and a lid portion, the side portions defining a surface for abutting the first layer of the substrate, and the lid portion being disposed over and spaced from the first layer of the substrate when the circuit components are supported on the substrate and the cover member is abutted to the substrate, the cover member composed of a plurality of layers; and a sensor comprising at least one conduction path disposed in at least one of the layers below the first layer of the substrate, at least one conduction path disposed in at least one of the layers of the cover member, and a plurality of vias disposed in the side portions of the cover member, each via comprising an electrically conductive material connecting at least one conduction path in the layers of the cover member to the surface of the cover member.
