• Abstract: This letter explores the positive side of the adversarial attack for the security-aware semantic communication system. Specifically, a pair of matching pluggable modules is installed: one after the semantic transmitter and the other before the semantic receiver. The module at transmitter uses a trainable adversarial residual network (ARN) to generate adversarial examples, while the module at receiver employs another trainable ARN to remove the adversarial attacks and the channel noise. To mitigate the threat of semantic eavesdropping, the trainable ARNs are jointly optimized to minimize the weighted sum of the power of adversarial attack, the mean squared error of semantic communication, and the confidence of eavesdropper correctly retrieving private information. Numerical results show that the proposed scheme is capable of fooling the eavesdropper while maintaining the high-quality semantic communication.

  We develop a novel adversarial learning-based implicit semantic-aware communication architecture (iSAC) We prove that by applying iSAC, the destination user can always learn an inference rule that matches the true inference rule of the source messages. Experimental results show that the proposed iSAC can offer up to a 19.69 dB improvement over existing non-inferential communication solutions.

  This paper highlights vulnerabilities of deep learning-driven semantic communications to backdoor (Trojan) attacks. Backdoor attack can effectively change the semantic information transferred for poisoned input samples to a target meaning. Design guidelines are presented to preserve the meaning of transferred information in the presence of backdoor attacks.
