Abstract

Semantic communications in 6G networks promise to revolutionize data transmission by focusing on the meaning of information rather than raw bits, enabling efficient and context-aware applications such as autonomous vehicles, telemedicine, and industrial automation. However, the semantic nature of data introduces significant privacy and security challenges, including semantic leakage, adversarial attacks, and trust gaps in multi-party communications. To address these challenges, this paper propose a secure semantic communication framework that enforces zero-trust attestation via zkSNARKs, implements cross-layer encryption, validates semantic integrity with XAI concept alignment, and ensures quantum resilience through lattice-based orchestration. Evaluations on 6G environment show SG-SHIELD reduces attack surfaces and block command injections without compromising URLLC requirements. By securing the transition from interconnection to intelligent interconnection, it provides the foundational trust layer for privacy-preserving, attack-resistant 6G semantic ecosystems.
