摘要:

最近的工作表明了对抗性机器学习对为射频机器学习(RFML)应用开发的深度神经网络(DNN)的影响。虽然这些攻击已被证明是成功地破坏窃听者的性能,但它们无法完全支持成功的预期通信的主要目标。为了解决这个问题,最近开发了一种通信感知攻击框架,通过DNN的新用途智能地创建对抗性通信信号,可以在逃避和预期通信的对立目标之间实现更有效的平衡。鉴于前向纠错(FEC)编码在大多数部署的系统中几乎无处不在地使用以纠正出现的错误,将FEC并入该框架中是该先前工作的自然扩展,并且将允许在更不利的环境中改进性能。因此,这项工作提供了贡献的框架,通过改进的损失函数和设计考虑因素,将固有的知识使用的FEC码内发送的信号。性能分析表明,FEC编码改进了通信感知对抗攻击,即使没有假设编码方案的明确知识,并且允许在平衡逃避和预期通信的相反目标方面优于现有技术的改进性能。

英文摘要:

Recent work has shown the impact of adversarial machine learning on deep neural networks (DNNs) developed for Radio Frequency Machine Learning (RFML) applications. While these attacks have been shown to be successful in disrupting the performance of an eavesdropper, they fail to fully support the primary goal of successful intended communication. To remedy this, a communications-aware attack framework was recently developed that allows for a more effective balance between the opposing goals of evasion and intended communication through the novel use of a DNN to intelligently create the adversarial communication signal. Given the near ubiquitous usage of forward error correction (FEC) coding in the majority of deployed systems to correct errors that arise, incorporating FEC in this framework is a natural extension of this prior work and will allow for improved performance in more adverse environments. This work therefore provides contributions to the framework through improved loss functions and design considerations to incorporate inherent knowledge of the usage of FEC codes within the transmitted signal. Performance analysis shows that FEC coding improves the communications aware adversarial attack even if no explicit knowledge of the coding scheme is assumed and allows for improved performance over the prior art in balancing the opposing goals of evasion and intended communications.
