Conceitos essenciais
Semantic communication networks (SemComNet) represent a promising paradigm for enabling intelligent multi-agent interactions, but face significant security and privacy threats that hinder its widespread adoption.
Resumo
This paper provides a comprehensive survey of SemComNet, focusing on its architecture, security, and privacy aspects.
The authors first introduce a three-layer architecture for SemComNet, comprising the control layer, semantic transmission layer, and cognitive sensing layer. The control layer manages shared knowledge bases, schedules tasks, and allocates resources. The semantic transmission layer enables efficient semantic-oriented information delivery among agents. The cognitive sensing layer integrates human-like cognitive processing to perceive the environment, infer agent intents, and accumulate knowledge.
The authors then outline a taxonomy of security and privacy threats across the three layers of SemComNet. At the control layer, threats include sponge examples attacks, knowledge base poisoning, and desynchronization of knowledge bases. The semantic transmission layer faces risks such as semantic data poisoning, semantic adversarial attacks, and semantic jamming. The cognitive sensing layer is vulnerable to threats like false data injection, free-riding, and impersonation attacks.
The paper reviews existing defense approaches and discusses their potential for establishing a secure, trustworthy, and privacy-preserving SemComNet. Finally, the authors present future research directions, including reliable SemComNet, trust management, data and knowledge security, secure personalized service provision, green SemComNet architecture, explainable semantic models, SemComNet orchestrated with generative AI, endogenous secure SemComNet, and adaptive SemComNet design.
