Beamforming and Trajectory Optimization for Aerial RIS-Aided Secure ISAC via Model Predictive Control

Zhendong Li, Zesheng Zhang, Zhou Su et al. · 2026

This paper proposes a novel aerial reconfigurable intelligent surface (RIS)-aided secure integrated sensing and communication (ISAC) architecture. An unmanned aerial vehicle (UAV)-mounted RIS establishes virtual line-of-sight links to bypass blockages, serving legitimate users while sensing potential eavesdroppers. To …

SparLeak: Privacy Leakage from Sparse Attention in LLM Inference on Shared GPUs

Fahao Chen, Linkang Du, Jinhao Zhou et al. · 2026

Sparse attention is widely used to accelerate long-context inference in modern large language models (LLMs), but its input-dependent execution behavior introduces previously unexplored privacy risks. We identify a new GPU micro-architectural side channel, termed Sparsity-Induced Memory Access (SIMA), which arises from …
