Data Agents Under Attack: Vulnerabilities in LLM-Driven Analytical Systems
Kuncan Wang, Ziting Wang, Peizhuo Lv +4
Data agents integrate LLM-driven reasoning with relational data access, executable analytical tools, and multi-step workflow orchestration, making them increasingly central to ente…
Defense against Poisoning Attacks under Shuffle-DP
Siyi Wang, Qiyao Luo, Yihua Hu +6
Differential Privacy (DP) has become the gold standard for protecting individual privacy in data analytics, and the shuffle-DP model has attracted significant attention from both a…
Secure Query Processing with Linear Complexity
Qiyao Luo, Yilei Wang, Wei Dong +1
We present LINQ, the first join protocol with linear complexity (in both running time and communication) under the secure multi-party computation model (MPC). It can also be extend…
Almost Instance-optimal Clipping for Summation Problems in the Shuffle Model of Differential Privacy
Wei Dong, Qiyao Luo, Giulia Fanti +2
Differentially private mechanisms achieving worst-case optimal error bounds (e.g., the classical Laplace mechanism) are well-studied in the literature. However, when typical data a…
