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…
GLST: Defending Confidence-Driven V2X Collaborative Perception Against Stealthy Multi-Attacker Feature Injection
Ji He, Ying Wang, Lijie Zheng +3
Collaborative perception (CP) improves autonomous-driving perception by enabling connected vehicles to exchange intermediate features via V2X. Confidence-driven sparse communicatio…
From Intent to Infrastructure: LLM-Driven Agent Compilers for ISAC Networks
Lijie Zheng, Xudong Zhong, Baoquan Ren +3
Integrated sensing and communications (ISAC) is moving from proof-of-concept demonstrations to system-level deployment in sixth-generation (6G) networks. Because sensing and commun…
LLM-Aided Joint Secrecy Precoding and Trajectory for RSMA-Based Heterogeneous UAV Networks
Lijie Zheng, Ji He, Shih Yu Chang +1
This paper investigates secure communications in rate-splitting multiple access (RSMA) enabled heterogeneous UAV networks, where multiple UAVs collaboratively serve ground terminal…
