Center node: "communication without interception defense against deep learning based modulation detection"
  Abstract: We consider a communication scenario, in which an intruder, employing a deep neural network (DNN), tries to determine the modulation scheme of the intercepted signal. Our aim is to minimize the accuracy of the intruder, while guaranteeing that the intended receiver can still recover the underlying message with the highest reliability. This is achieved by constellation perturbation at the encoder, similarly to adversarial attacks against DNN-based classifiers. In the latter perturbation is limited to be imperceptible to a human observer, while in our case perturbation is constrained so that the message can still be reliably decoded by the legitimate receiver which is oblivious to the perturbation. Simulation results demonstrate the viability of our approach to make wireless communication secure against DNN-based intruders with minimal sacrifice in the communication performance.
