Post-Quantum Secure Semantic Communication With Discrete Latent Representations

This research paper proposes a post-quantum secure semantic communication (PQSC) framework that protects data transmission against both eavesdropping and future quantum computing threats. The framework combines learning with errors (LWE, a type of encryption believed to resist quantum attacks) with VQ-VAE (a neural network compression technique) to send information efficiently while keeping it secure. Experiments show this approach works better than existing methods across different network conditions and data types.
