Abstract
A system for generating a tamper detection signal indicating tampering with one or more circuits of an integrated circuit (IC) includes a tamper detection module, and wire-pairs connected to the tamper detection module and arranged in a winding configuration to form a wire-mesh. The wire-mesh is placed a predefined distance from the circuits. The tamper detection module generates and provides serial bit-streams to the wire-pairs for detecting a breach in the wire-mesh by an external probe.
