一句话:提出基于 fuzzing 的查询高效黑盒攻击 DeepSearch,能更有效找到图像分类器的对抗输入。
深度神经网络在图像分类任务上表现优异,但容易受到对抗攻击;现有生成对抗输入的方法包括白盒与黑盒攻击。本文提出 DeepSearch,一种基于 fuzzing 的新型黑盒攻击,专用于图像分类器,并强调查询效率。尽管方法简单,实验表明 DeepSearch 在寻找对抗输入方面比当前先进的黑盒方法更有效,同时能够生成相比这些方法更隐蔽的对抗输入。该工作为黑盒对抗攻击提供了一种简洁且高效的方案。
Although deep neural networks have been very successful in image-classification tasks, they are prone to adversarial attacks. To generate adversarial inputs, there has emerged a wide variety of techniques, such as black- and whitebox attacks for neural networks. In this paper, we present DeepSearch, a novel fuzzing-based, query-efficient, blackbox attack for image classifiers. Despite its simplicity, DeepSearch is shown to be more effective in finding adversarial inputs than state-of-the-art blackbox approaches. DeepSearch is additionally able to generate the most subtle adversarial inputs in comparison to these approaches.
