Abstract:In this work, we investigate a practical consideration for Electromagnetic (EM) side-channel analysis, namely, positioning EM probe at the best location for an efficient attack, requiring fewer traces to reveal the secret key of cryptographic engines. We present Multi-Layer Perceptron (MLP) based probe positioning and EM analysis method, defining it as a classification problem by dividing the chip surface scanned by the EM probe into virtual grids, and identifying each grid location by a class label. The MLP, trained to identify the location given a single EM trace, achieves 99.55\% accuracy on average for traces captured during different acquisition campaigns.
