One Pipeline Does Not Fit All: TAILOR, a Type- and State-Aware Framework for CVE Reproduction
Ji He, Huang Zhang, Lijie Zheng +2
Growing vulnerability disclosure and widespread software reuse increase security teams' need for reproducible evidence to diagnose vulnerabilities, validate patches, and build regr…
Know the Normal, Track the Attack: Context-Grounded and Stateful LLM Investigation over System Provenance
Lijie Zheng, Ji He, Ying Wang +2
Provenance-based intrusion detection systems (PIDSs) identify suspicious activity in audit streams, but their outputs remain difficult to turn into coherent attack narratives. Dire…
Not All Relations Are Equal: Relation-Balanced and Calibrated Graph Learning for Provenance-Based Intrusion Detection
Lijie Zheng, Ji He, Zhiwei Zhang +3
Provenance-Based Intrusion Detection Systems (PIDSs) detect Advanced Persistent Threats (APTs) by analyzing system interactions. However, existing methods largely treat relations u…
CT-OpenMax: A Novel Open-Set WiFi RF Fingerprinting Method via Center Constrained Learning and Confidence-Guided Tail Modeling
Yuanyu Zhang, Junjie Yang, Ji He +3
Radio frequency fingerprinting (RFF) enables device authentication from transmitter-specific hardware imperfections, but practical deployment requires cross-environment open-set re…
IriSig-Spoof: A Real-World Benchmark for Time-Robust Satellite RF Fingerprinting and Spoofing Detection
Shichang Guo, Yuanyu Zhang, Shuangrui Zhao +3
Low Earth orbit (LEO) satellite Internet is becoming critical communications infrastructure, yet its open wireless links remain vulnerable to satellite impersonation and signal spo…
GalSAS-SDR-SIM: An End-to-End Simulation Platform for Galileo Signal Authentication Service

Practical Spoofing Attacks against Galileo OSNMA with Time-Synchronization Manipulation
Haiyang Wang, Yuanyu Zhang, Yangke Tan +4
Galileo launched the Open Service Navigation Message Authentication (OSNMA) to defend against spoofing attacks. This paper identifies an artificially manipulated time synchronizati…
Covert Multicast in UAV-Enabled Wireless Communication Systems With One-hop and Two-hop Strategies
Wenhao Zhang, Ji He, Yuanyu Zhang
This paper delves into the time-efficient covert multicast in a wireless communication system facilitated by Unmanned Aerial Vehicle (UAV), in which the UAV aims to disseminate a c…
On Achievable Covert Communication Performance under CSI Estimation Error and Feedback Delay
Jiaqing Bai, Ji He, Yanping Chen +2
Covert communication's effectiveness critically depends on precise channel state information (CSI). This paper investigates the impact of imperfect CSI on achievable covert communi…
Covert Communication in Hybrid Microwave/mmWave A2G Systems with Transmission Mode Selection
Wenhao Zhang, Ji He, Yulong Shen +1
