Abstract
An apparatus embodiment includes an integrated circuit (IC) and breach-detection circuitry. The IC includes data storage circuitry, a power grid configured to distribute power to the data storage circuitry, and a plurality of nodes distributed over at least one sensitive region of the IC. The breach-detection circuitry monitors power grid integrity at the at least one sensitive region of the IC and detects an event indicative of a breach by an external probe at a portion of the at least one sensitive region in response to floating node detection or a change in voltage at one of the plurality of nodes.
