Abstract. Deep Neural Networks (DNNs) are widely used for prediction and classification tasks. However, they are vulnerable to a variety of threats, including model extraction, evasion and inversion attacks. Model extraction attacks steal DNN models, which is a threat to intellectual property, data privacy, and security. We propose a novel DNN architecture extraction attack called EZClone, which uses aggregate GPU profiles as a side-channel information to reconstruct DNN model from an execution. We find that EZClone can correctly predict the architecture of all PyTorch vision architectures with 100% accuracy. This is the highest accuracy achieved by any attack with the same adversarial constraints using side-channel information. Prior work has shown that once a DNN has been successfully cloned, further attacks such as model evasion or model inversion can be accelerated significantly. This talk will also discuss side-channel leakage mitigation techniques.
