Closed-World Resolution Against Tool Hallucination in LLM Agents
Tool-augmented large language model (LLM) agents fail in a way no tool-selection or tool-security method addresses: they call tools that do not exist and pass arguments no schema declares.Beyond Private Training: The New Landscape of AI Privacy
Retrieval-augmented systems increasingly rely on vector indexes that may retain deleted items in their search graph.Safety Beyond the Interface: Detecting Harm via Latent States in Large Language Models
Autonomous systems increasingly rely on Large Language Models (LLMs) yet the safety infrastructure surrounding these models introduces latency and compute overhead.Not All Relations Are Equal: Relation-Balanced and Calibrated Graph Learning for Provenance-Based Intrusion Detection
Provenance-Based Intrusion Detection Systems (PIDSs) detect Advanced Persistent Threats (APTs) by analyzing system interactions.A Cyber Range Evaluation of Autonomous Network Incident Response Agents
We test the performance of agents for automated network intrusion response in a cyber range intended for human operator training.The MAL Simulator: Cyber Operations Simulation based on Attack & Defense Graphs
We have developed the MAL Simulator, a cyber operation simulator based on the Meta Attack Language (MAL).What Breaks Local Watermarks? A Robustness Benchmark for Local Invisible Image Watermarking
Local image watermarking embeds an invisible signal into selected image regions rather than spreading it across the entire image, enabling payload recovery from specific objects or regions without…OptiPrime: Optimizing Private Inference through Protocol-Hardware Co-design
Private deep neural network (DNN) inference based on hybrid homomorphic encryption (HE) and multi-party computation (MPC) can protect user data with a formal guarantee, but at the cost of…TasmScan: Continuation-Aware Taint Analysis for TVM Bytecode with Savelist Abstraction
The Open Network (TON), with a peak market capitalization exceeding $20 billion and over 175 million activated on-chain addresses, relies on the TVM (TON Virtual Machine) to execute smart contracts.Cross-Domain Inference for Human Localization: Applying Wi-Fi RSSI Data to CSI-Trained Models
Wi-Fi signal data can be used to compromise the privacy of individuals.Can We Stop The Ads? Taxonomy and Characterization of Smartphone Splash Ads and Existing Countermeasures
Splash ads are full-screen advertisements that pop up and appear as the first interaction page when users start an app, often tricking users into unknowingly activating certain trigger mechanisms…RobResilience: Implementing and Evaluating a Resilience Framework for Cyber-Physical Embodied Systems
In embodied cyber-physical systems, active cyberattacks pose an immediate threat not just to data, but to physical integrity and human safety.Intrinsic-Dimensional Wasserstein Guarantees for Private Synthetic Measures
We study an $\varepsilon$-differentially private synthetic measure for $n$ points in $[0,1]^d$ by applying the existing PrivTree algorithm to construct an adaptive binary partition and then…Making AI-Assisted Claims Independently Challengeable: Publication Authority and a Protocol for Falsifiable Publication Records
AI-assisted claims can appear authoritative when evidence, analysis, human authorization, presentation, and correction history refer to different states.Physics-Constrained Digital Twins for Sensor Integrity in Urban Pedestrian Flow: Detecting Stealthy False Data Injection with Conformal Guarantees
City pedestrian counting systems now feed economic indicators, planning decisions and safety operations, yet the twins built on top of them treat the incoming stream as ground truth.Trust propagation and structural containment in Multi-agent LLM pipelines
Multi-agent LLM systems increasingly automate tasks involving agents with different levels of privilege, creating a security risk in which a compromised low-privilege agent can influence a…Tight Lower Bounds for Differentially Private Continual Counting
The Binary Tree Mechanism is a standard algorithm for differentially private continual counting, but its asymptotic optimality under pure differential privacy has remained unresolved since its…Reflections on Trusting Trust, Revisited: Contaminating Self-Modifying AI Coding Agents with Poisoned Benchmarks
Thompson's "Reflections on Trusting Trust" showed that a compiler can be poisoned to reinsert its own backdoor, so that even recompiling clean source reproduces the Trojan.Investigating Adversarial Robustness of Heterogeneous Cooperative Perception
Heterogeneous cooperative perception (CP) enables connected vehicles with diverse sensor setups to share spatial awareness via compact feature maps, where receivers reconcile these maps using…ActGuard: Pre-execution Action Auditing against Indirect Prompt Injection in LLM Agents
Large language model (LLM) agents interact with external environments through tool invocation, but tool outputs can also expose them to indirect prompt injection (IPI) attacks.
