Is Semantic Communications Secure? A Tale of Multi-Domain Adversarial Attacks. (arXiv:2212.10438v1 [cs.CR])

Semantic communications seeks to transfer information from a source while
conveying a desired meaning to its destination. We model the
transmitter-receiver functionalities as an autoencoder followed by a task
classifier that evaluates the meaning of the information conveyed to the
receiver. The autoencoder consists of an encoder at the transmitter to jointly
model source coding, channel coding, and modulation, and a decoder at the
receiver to jointly model demodulation, channel decoding and source decoding.
By augmenting the reconstruction loss with …
