Abstract
Apparatus, method and program product may detect an attempt to tamper with a microchip by detecting an unacceptable alteration in a measured capacitance associated with capacitance structures proximate the backside of a microchip. The capacitance structures typically include metallic shapes and may connect using through-silicon vias to active sensing circuitry within the microchip. In response to the sensed change, a shutdown, spoofing, self-destruct or other defensive action may be initiated to protect security sensitive circuitry of the microchip.
