论文摘要

DNN容易受到对抗性示例的影响,这对安全至关重要的系统提出了极大的安全问题。在本文中,提出了一种新颖的基于自适应的物理攻击(AP-PA)框架,旨在生成在物理动力学和变化尺度上具有自适应的对抗斑块,并且可以通过这些斑点可以隐藏特定目标。此外,对抗性贴片还具有针对同一班级所有目标的攻击效果,并在目标外(无需涂抹目标对象),并且在物理世界中足够强大。此外,设计了新的损失,以考虑更多可检测到的对象的可用信息,以优化对抗贴片,这可以显着提高贴片的攻击效果(分别在白色盒子和黑盒子设置中,平均精度下降到最高87.86%和85.48%)和优化的效率。我们还建立了第一个全面,连贯和严格的基准之一,以评估对抗斑块对空中检测任务的攻击功效。最后,进行了几个按比例缩放的实验进行身体进行,以证明详细的对抗斑块可以在动态物理环境中成功欺骗空中检测算法。该代码可在https://github.com/jiaweilian/ap-pa上找到。

DNNs are vulnerable to adversarial examples, which poses great security concerns for security-critical systems. In this paper, a novel adaptive-patch-based physical attack (AP-PA) framework is proposed, which aims to generate adversarial patches that are adaptive in both physical dynamics and varying scales, and by which the particular targets can be hidden from being detected. Furthermore, the adversarial patch is also gifted with attack effectiveness against all targets of the same class with a patch outside the target (No need to smear targeted objects) and robust enough in the physical world. In addition, a new loss is devised to consider more available information of detected objects to optimize the adversarial patch, which can significantly improve the patch's attack efficacy (Average precision drop up to 87.86% and 85.48% in white-box and black-box settings, respectively) and optimizing efficiency. We also establish one of the first comprehensive, coherent, and rigorous benchmarks to evaluate the attack efficacy of adversarial patches on aerial detection tasks. Finally, several proportionally scaled experiments are performed physically to demonstrate that the elaborated adversarial patches can successfully deceive aerial detection algorithms in dynamic physical circumstances. The code is available at https://github.com/JiaweiLian/AP-PA.
