A Compact Probe for EM Side-Channel Attacks on Cryptographic Systems
Frank T. Werner, Antonije R. Djordjevic, Alenka G. Zajic · 2019
A shielded loop probe designed for evaluating EM side-channels attacks on cryptographic systems is described. This probe is compact and is sensitive enough to measure extremely weak signals that usually comprise EM side-channels. Furthermore, this probe can greatly suppress the influence of the electric field on its measurements. At its center frequency, the probe has a sensor factor of -0.17 dB S/m and electric field suppression ratio of 30.18 dB.
