论文摘要
最近,随着深度学习在遥感图像(RSI)字段中的应用,与传统技术相比,RSI的分类精度已得到显着提高。但是,即使是最先进的对象识别卷积神经网络也被普遍的对抗扰动(UAP)所欺骗。 UAP的研究主要限于普通图像,并且尚未研究RSI。为了探索RSIS UAP的基本特征,本文提出了一种新的方法,将编码器 - 编码器网络与注意力机制结合起来,以生成RSIS的UAP。首先,前者用于生成UAP,该UAP可以更好地学习扰动的分布,然后将后者用于找到RSI分类模型所关心的敏感区域。最后,生成的区域用于微调扰动,从而使模型分类较少,而扰动较少。实验结果表明,UAP可能会使分类模型错误分类,并且我们提出的方法对RSI数据集的攻击成功率高达97.09%。
Recently, with the application of deep learning in the remote sensing image (RSI) field, the classification accuracy of the RSI has been dramatically improved compared with traditional technology. However, even the state-of-the-art object recognition convolutional neural networks are fooled by the universal adversarial perturbation (UAP). The research on UAP is mostly limited to ordinary images, and RSIs have not been studied. To explore the basic characteristics of UAPs of RSIs, this paper proposes a novel method combining an encoder-decoder network with an attention mechanism to generate the UAP of RSIs. Firstly, the former is used to generate the UAP, which can learn the distribution of perturbations better, and then the latter is used to find the sensitive regions concerned by the RSI classification model. Finally, the generated regions are used to fine-tune the perturbation making the model misclassified with fewer perturbations. The experimental results show that the UAP can make the classification model misclassify, and the attack success rate of our proposed method on the RSI data set is as high as 97.09%.
