Abstract
Provided is a method for masking a sensitive signal by injecting noise into planes of a printed circuit board (PCB). The method comprises detecting, by a secondary integrated circuit (IC), a noise signal on a shared plane of a PCB that includes the secondary IC. The noise signal may be analyzed to determine the characteristics of the noise signal. A masking signal may be generated based on the characteristics. The masking signal may then be injected onto the shared plane.
