• Abstract: Although deep generative models such as Defense-GAN and Defense-VAE have made significant progress in terms of adversarial defenses of image classification neural networks, several methods have been found to circumvent these defenses. Based on Defense-VAE, in our research we introduce several methods to improve the robustness of defense models. The methods introduced in this paper are straight forward yet show promise over the vanilla Defense-VAE. With extensive experiments on MNIST data set, we have demonstrated the effectiveness of our algorithms against different attacks. Our experiments also include attacks on the latent space of the defensive model. We also discuss the applicability of existing adversarial latent space attacks as they may have a significant flaw.

  We introduce DUCD, a universal black-box defense method that does not require access to the target model's parameters or architecture. Our approach involves querying the target model by querying it with data, creating a white-box surrogate while preserving data privacy. Experiments on multiple image classification datasets show that DUCD not only outperforms existing black-box defenses but also matches the accuracy of white-box defenses.

  We propose a new key-based defense focusing on both efficiency and robustness. We build upon the previous defense with two major improvements: (1) efficient training and (2) optional randomization. Experiments were carried out on the ImageNet dataset, and the proposed defense was evaluated against an arsenal of state-of-the-art attacks.

  Federated Learning (FL) facilitates decentralized machine learning model training, preserving data privacy, lowering communication costs, and boosting model performance through diversified data sources. FL faces vulnerabilities such as poisoning attacks, undermining model integrity with both untargeted performance degradation and targeted backdoor attacks. We define a new notion of strong adaptive adversaries, capable of adapting to multiple objectives simultaneously. MESAS is the first defense robust against strong adaptive adversaries, effective in real-world data scenarios, with an average overhead of just 24.37 seconds.

  It is becoming increasingly imperative to design robust ML defenses. Recent work has found that many defenses that initially resist state-of-the-art attacks can be broken by an adaptive adversary. We take steps to simplify the design of defenses and argue that white-box defenses should eschew randomness when possible.

  Projected Gradient Descent (PGD) attack has been demonstrated to be one of the most successful adversarial attacks. We propose Scale-Invariant Adversarial Attack (SI-PGD), which utilizes the angle between the features in the penultimate layer and the weights in the softmax layer to guide the generation of adversaries.

  In this work, we study a simple but promising defense technique, dubbed Random Noise Defense (RND) against query-based black-box attacks. It is lightweight and can be directly combined with any off-the-shelf models and other defense strategies. In this work, we present solid theoretical analyses to demonstrate that the defense effect of RND against the query-based black-box attack and the corresponding adaptive attack heavily depends on the magnitude ratio.
