使用深度对抗神经网络学习安全调制

Learning Secured Modulation With Deep Adversarial Neural Networks

Hesham Mohammed, Dola Saha

摘要:

对异构设备利用无线频谱的兴趣日益增长,迫使我们重新考虑物理层安全性,以保护传输的波形不被窃听。我们提出了一个端到端的对称密钥神经加密和解密算法与调制技术,它仍然无法破译的窃听者,配备了相同的神经网络和训练相同的数据集作为预期的用户。我们将加密和调制作为一个联合问题来解决,为此我们将比特映射到复杂的模拟信号,而不坚持任何特定的加密算法或调制技术。我们通过训练,在我们信任的神经网络对之间合作学习加密和解密算法,而窃听者的模型则在相同的数据上进行对抗训练,以最大限度地减少错误。我们引入了一个离散的激活层与定义的梯度,以打击在有损信道中的噪声。我们的研究结果表明,一对受信任的用户可以在干净和嘈杂的信道中交换数据位,而训练有素的对手无法破译数据。

英文摘要:

Growing interest in utilizing the wireless spectrum by heterogeneous devices compels us to rethink the physical layer security to protect the transmitted waveform from an eavesdropper. We propose an end-to-end symmetric key neural encryption and decryption algorithm with a modulation technique, which remains undeciphered by an eavesdropper, equipped with the same neural network and trained on the same dataset as the intended users. We solve encryption and modulation as a joint problem for which we map the bits to complex analog signals, without adhering to any particular encryption algorithm or modulation technique. We train to cooperatively learn encryption and decryption algorithms between our trusted pair of neural networks, while eavesdropper's model is trained adversarially on the same data to minimize the error. We introduce a discrete activation layer with a defined gradient to combat noise in a lossy channel. Our results show that a trusted pair of users can exchange data bits in both clean and noisy channels, where a trained adversary cannot decipher the data.
