Abstract

Abstract: Recently, deep learning has been introduced as an interesting alternative to perform side-channel attacks, which are nowadays well-known threats to secure systems in the electronic equipment. However, these end-to-end devices can limit their adoption in the complex power traces due to lack of transparency. In this work, we propose a new deconvolution architecture to evaluate the security of secure systems, which combines gradient calculation and deconvolutional operation. First, we use the U-Net-like structure to classify to verify the positive impact of the deconvolution on classification. Next, we propose a gradient deconvolution network (GDN), which combines gradient calculation and model training firstly. The result of gradient calculation locates the leakage and transfers the information to the model to get a better training effect. Finally, we evaluate our methodology with the public datasets and provide visualization of Points of Interest (POIs). Graphical abstract: Highlights: Deconvolution operation was used as a part of the classifier in side-channel attacks. The gradient map can be displayed and improve the model training effect. A structure combines gradient calculation and deconvolution operation was proposed.
