摘要:

各种机器学习方法对对抗性示例的脆弱性最近在文献中进行了探索。使用这些脆弱方法的电力系统面临着对抗性示例的巨大威胁。为此,我们首先提出了一个信号特定的方法和一个通用的信号不可知的方法来攻击电力系统使用生成的对抗性的例子。本文还提出了基于可传递特征的黑盒攻击和上述两种方法,并对它们进行了评价。然后,我们采用对抗训练来保护系统免受对抗攻击。实验分析表明,我们的信号特定的攻击方法相比,FGSM(快速梯度符号法)提供更少的扰动,我们的信号不可知的攻击方法可以产生干扰欺骗大多数自然信号的概率很高。此外,基于通用信号无关算法的攻击方法比基于特定信号算法的攻击方法具有更高的黑盒攻击的传送率。此外,结果表明,所提出的对抗性训练提高了电力系统对抗性的例子的鲁棒性。

英文摘要:

Vulnerability of various machine learning methods to adversarial examples has been recently explored in the literature. Power systems which use these vulnerable methods face a huge threat against adversarial examples. To this end, we first propose a signal-specific method and a universal signal-agnostic method to attack power systems using generated adversarial examples. Black-box attacks based on transferable characteristics and the above two methods are also proposed and evaluated. We then adopt adversarial training to defend systems against adversarial attacks. Experimental analyses demonstrate that our signal-specific attack method provides less perturbation compared to the FGSM (Fast Gradient Sign Method), and our signal-agnostic attack method can generate perturbations fooling most natural signals with high probability. What's more, the attack method based on the universal signal-agnostic algorithm has a higher transfer rate of black-box attacks than the attack method based on the signal-specific algorithm. In addition, the results show that the proposed adversarial training improves robustness of power systems to adversarial examples.
