When Agents Go Rogue: Activation-Based Detection of Malicious Behaviors in Multi-Agent Systems
Haowen Xu, Xue Tan, Lei Ma +6
While enabling effective collaboration on complex tasks, LLM-based Multi-Agent Systems (MAS) face critical security challenges due to vulnerabilities at the agent and interaction l…
EMPalm: Exfiltrating Palm Biometric Data via Electromagnetic Side-Channel
Haowen Xu, Tianya Zhao, Xuyu Wang +4
Palm recognition has emerged as a dominant biometric authentication technology in critical infrastructure. These systems operate in either single-modal form, using palmprint or pal…
Generalizable and Interpretable RF Fingerprinting with Shapelet-Enhanced Large Language Models
Tianya Zhao, Junqing Zhang, Haowen Xu +3
Deep neural networks (DNNs) have achieved remarkable success in radio frequency (RF) fingerprinting for wireless device authentication. However, their practical deployment faces tw…
RevPRAG: Revealing Poisoning Attacks in Retrieval-Augmented Generation through LLM Activation Analysis
Xue Tan, Hao Luan, Mingyu Luo +3
Retrieval-Augmented Generation (RAG) enriches the input to LLMs by retrieving information from the relevant knowledge database, enabling them to produce responses that are more acc…
Enabling Practical and Privacy-Preserving Image Processing
Chao Wang, Shubing Yang, Xiaoyan Sun +2
Fully Homomorphic Encryption (FHE) enables computations on encrypted data, preserving confidentiality without the need for decryption. However, FHE is often hindered by significant…
HuntFUZZ: Enhancing Error Handling Testing through Clustering Based Fuzzing
Jin Wei, Ping Chen, Jun Dai +4
Testing a program's capability to effectively handling errors is a significant challenge, given that program errors are relatively uncommon. To solve this, Software Fault Injection…
