Post-Quantum Secure Semantic Communication With Discrete Latent Representations

Summary

This paper proposes PQSC, a post-quantum secure semantic communication framework that integrates learning with errors (LWE) encryption into a VQ-VAE-based SemCom system. The authors report that PQSC resists quantum attacks and chosen-plaintext attacks, and that it consistently outperforms baseline methods across datasets, channel conditions and SNR levels. Channel coding and modulation are simulated with Nvidia Sionna.
