Multi-Mode Configurable Magnetic Antenna Array for Detecting and Defending Against Malicious Attacks on Semiconductor Integrated Circuits

A computer-implemented method comprising:

• receiving, by one or more processors, frequency spectrum data based on induced voltage measured of an integrated circuit, the spectrum data received from a magnetic antenna array embedded within the integrated circuit, the magnetic antenna array comprising a wire grid, wherein the wire grid comprises (i) a wire grid spanning two metal layers comprising horizontal wires and vertical wires, (ii) a switch at each intersection of the horizontal wires and the vertical wires, wherein each switch comprises a transmission gate, and (iii) one or more sensing areas;
• determining, by the one or more processors, one or more spectrum signatures in the spectrum data by comparing the spectrum data with spectrum data without active hardware Trojans;
• for each of the spectrum signatures, analyzing, by the one or more processors, one or more frequency components of a spectrum signature in a time domain based on a magnitude change as a function of time;
• and
• determining, by the one or more processors, an identification of one or more hardware Trojans by comparing the one or more frequency components of the spectrum signature with frequency components of one or more known hardware Trojans.

An integrated circuit comprising:

• a target circuit;
• and
• a magnetic antenna array embedded within the target circuit, the magnetic antenna array comprising one or more antenna loops formed by a plurality of connections between a plurality of intersecting horizontal and vertical wires, the magnetic antenna array configured to reduce magnetic field leakage by:
• detecting a magnetic field leakage of a target circuit by configuring the magnetic antenna array to operate in a detection mode;
• inversely amplifying the one or more antenna loops based on the magnetic field leakage;
• and
• canceling the magnetic field leakage by configuring the magnetic antenna array in a cancelation mode that injects electrical currents into the one or more antenna loops of the magnetic antenna array.
