论文摘要
最近，后门攻击已成为对深神经网络（DNN）模型安全性的新兴威胁。迄今为止，大多数现有研究都集中于对未压缩模型的后门攻击。尽管在实际应用中广泛使用的压缩DNN的脆弱性尚未得到利用。在本文中，我们建议研究和发展针对紧凑型DNN模型（RIBAC）的强大和不可感知的后门攻击。通过对重要设计旋钮进行系统分析和探索，我们提出了一个框架，可以以有效的方式学习适当的触发模式，模型参数和修剪口罩。从而同时达到高触发隐形性，高攻击成功率和高模型效率。跨不同数据集的广泛评估，包括针对最先进的防御机制的测试，证明了RIBAC的鲁棒性，隐身性和模型效率的高度。代码可从https://github.com/huyvnphan/eccv2022-ribac获得
Recently backdoor attack has become an emerging threat to the security of deep neural network (DNN) models. To date, most of the existing studies focus on backdoor attack against the uncompressed model; while the vulnerability of compressed DNNs, which are widely used in the practical applications, is little exploited yet. In this paper, we propose to study and develop Robust and Imperceptible Backdoor Attack against Compact DNN models (RIBAC). By performing systematic analysis and exploration on the important design knobs, we propose a framework that can learn the proper trigger patterns, model parameters and pruning masks in an efficient way. Thereby achieving high trigger stealthiness, high attack success rate and high model efficiency simultaneously. Extensive evaluations across different datasets, including the test against the state-of-the-art defense mechanisms, demonstrate the high robustness, stealthiness and model efficiency of RIBAC.
