Gradient-based attacks are global attacks, so the norm can reflect the perturbation limit of the attack on the image. In contrast, for the COCO datasets, the background occupies far more pixels than the target pixels. The norm constraint is to constrain each pixel as a whole, whereas in ...
However, subsequent research has shown that BIM exhibits relatively lower transferability, leading to less effective black-box attacks. 2.4. Momentum Iterative Fast Gradient Sign Method Due to the fact that the basic iterative method based on FGSM computes and accumulates gradients in each step during...

IV. ADVERSARIAL ATTACKS AGAINST SNNS 在这一部分中,我们首先简要介绍输入数据格式,然后详细说明我们的攻击方法的流程、方法和算法。 Input Data Format.SNN模型处理脉冲信号是很自然的。因此,考虑到包含脉冲事件的数据集,例如N-MNIST[33]和CIFAR10-DVS[34],这是首选。在这种情况下,输入最初是一个时空模式,每个元...
In this work, we explore the implications of Gradient Inversion attacks in FL and propose a novel defence mechanism, called Pruned Frequency-based Gradient Defence (pFGD), to mitigate these risks. Our defence strategy combines frequency transformation using techniques such as Discrete Cosine Transform...
