I Know What You See: Power Side-Channel Attack on Convolutional Neural Network Accelerators

no code implementations5 Mar 2018 Lingxiao Wei, Bo Luo, Yu Li, Yannan Liu, Qiang Xu

Deep learning has become the de-facto computational paradigm for various kinds of perception problems, including many privacy-sensitive applications such as online medical image analysis.

Towards Imperceptible and Robust Adversarial Example Attacks against Neural Networks

no code implementations15 Jan 2018 Bo Luo, Yannan Liu, Lingxiao Wei, Qiang Xu

Previous adversarial example crafting methods, however, use simple metrics to evaluate the distances between the original examples and the adversarial ones, which could be easily detected by human eyes.
