An Efficient Method for Localization of Magnetic Field Sources That Produce High-Frequency Side-Channel Emanations

Presented is a new, low-cost system for locating the strongest sources of high-frequency EM side-channel emanations on PCBs. These sources indicate the best locations to monitor or mitigate the leakage. The challenges inherent in both side-channel and high-frequency measurements are addressed through careful design of the measurement and localization system. The system is time efficient, requiring...
