Toward Polymorphic Backdoor against Semantic Communication via Intensity-Based Poisoning
Xiao Yang, Yuni Lai, Gaolei Li +4
Semantic Communication (SC) backdoor attacks aim to utilize triggers to manipulate the system into producing predetermined outputs via backdoored shared knowledge. Current SC backd…
Alkaid: Resilience to Edit Errors in Provably Secure Steganography via Distance-Constrained Encoding
Zhihan Cao, Gaolei Li, Jun Wu +3
While provably secure steganography provides strong concealment by ensuring stego carriers are indistinguishable from natural samples, such systems remain vulnerable to real-world…
SemCovert: Secure and Covert Video Transmission via Deep Semantic-Level Hiding
Zhihan Cao, Xiao Yang, Gaolei Li +3
Video semantic communication, praised for its transmission efficiency, still faces critical challenges related to privacy leakage. Traditional security techniques like steganograph…
From Bi-Level to One-Level: A Framework for Structural Attacks to Graph Anomaly Detection
Yulin Zhu, Yuni Lai, Kaifa Zhao +5
