Before Agents Act: Assurance-Aware Semantic Scheduling for Evidence Acquisition in Distributed Systems
Tool-using agents can initiate consequential infrastructure changes, yet evidence required for admission may expire while other checks run or depend on a shared fault domain.Coherence Rather Than Error Rate Governs Privacy in Multi-Tenant Quantum Computing
Multi-tenant computing enables providers of commercial cloud quantum processors to rent disjoint sectors of a device to independent users.Quantum Security of XOR of Permutations via Fourier Analysis
The XOR of two or more independent random permutations (XoP) is the prototypical pseudorandom function built from permutations achieving security beyond the birthday bound.CoDeL: Co-Evolutionary Defense against Indirect Prompt Injection in LLM-based Agents
Large language model (LLM)-based agents increasingly rely on external tools and content, exposing them to indirect prompt injection (IPI).How to Tame a Multi-Headed Hydra? Adaptive Multi-Category Safety Steering for Large Language Models
As large language models (LLMs) become increasingly widespread, preventing unsafe responses to harmful prompts is essential for their safe deployment.SEAD: A State-Based Perspective on Attack and Defense in Tool-Using Agents
Language-model agents increasingly use tools to act on external systems.Optimizing and Securing the Modern Watermarking Channel for Images
To comply with recent regulations requiring traceable generated content, modern watermarking has adopted multi-bit post-hoc watermarking schemes.CoSec: Benchmarking Agent Security in Communities
LLM agents operate in persistent collaborative environments involving multiple users, communities, memories, files, and tools.Physics-Attested Federated Learning: Securing Collaborative Anomaly Detection in Critical Water Infrastructure
Federated learning enables industrial operators to train shared intrusion detection models without disclosing proprietary operational telemetry.DGF-Bench: A Benchmark for Simulating and Auditing Deception Against Multi-Agent Governance Boards
Tool-using language-model agents can review enterprise projects as governance boards do: they read the evidence, apply written rules and decide whether the project may proceed.JevVibe: Efficient Classification-Guided Secure Code Generation
Large language models can generate functionally correct code that still contains security weaknesses, motivating repair pipelines that first diagnose a weakness type before deciding how to fix it.Before Acting, Change the State: Prospective State Intervention for Web Agents under Deceptive Interfaces
LLM-based Web agents can autonomously complete user tasks, yet deceptive interfaces can steer them toward outcomes that conflict with users' interests.SmartMemory: Detecting On-chain-off-chain Communication Inconsistency for Smart Contract via Memory-based Agent
Smart contracts underpin decentralized finance, where growing demand for on-chain/off-chain communication(OFC) has driven diverse applications such as cross-chain bridges, real-world asset…Cyclotomic Cosets: Hidden Subgroup and Quantum Sieving Algorithm for Prime-Power Moduli
The Learning With Errors (LWE) problem is a fundamental assumption in post-quantum cryptography.Still There, No Longer Seen: Exposing Compression-Induced Risk in Large Vision-Language Models
Visual token compression reduces the inference cost of Large Vision-Language Models (LVLMs).When Valid Tool Calls Change Meaning: Formation-Consistent Dispatch for LLM Agents
Tool-enabled agents form calls from model-visible interfaces, while hosts later select their implementation.Trajectory-Level Security Debt in LLM Coding Agents
LLM coding agents can traverse hundreds of intermediate code states before submitting a solution.TANGO: Watermarking Masked Diffusion Language Models in Token Pairs
Masked-diffusion language models fill in masked positions in parallel and in no fixed order.Zero Knowledge Proofs in Quantum Networks
Zero-knowledge proofs (ZKPs) enable the verification of a statement without revealing any information beyond its validity and constitute a fundamental primitive in cryptography and information theory.Planarian: Managing Agent State with Statepoints
LLM agents solve complex tasks by iteratively changing files, invoking local tools, and interacting with remote services, which modifies state across their local environment and remote services.
