The Power of Interaction in Locally Edge-Private Subgraph Counting
We study (non-induced) subgraph counting under interactive local edge differential privacy (LEDP).Quantum Advantage has Few Complexity Implications
We consider the complexity implications of proofs of quantumness and (quantum verifier) oblivious state preparation.From Claws to Conferences: Device-Independent Key Agreement Beyond Non-Signaling
Device-independent conference key agreement (DI-CKA) allows a group of users to establish a common secret key without trusting the internal operation of their quantum devices.Exploring the Privacy--Size Tradeoff for Differentially Private Self-Attentive Variational Autoencoders
Data tends to be most useful when it is shared, and the data most worth sharing is often the data that privacy obligations restrict.Assurance-Conditioned Continuous Authorization for Autonomous AI Agents
Autonomous software agents can act through tools, delegate work, and change their models or execution environments while earlier authorizations remain in flight.AQUA - A Modular Authentication Quality Modeling Framework
Authentication solutions are the key design, architectural, and implementation decisions that implement authentication security controls.Trinetra.Q: Statistical and Behavioral Detection of Attacks on the Quantum-Error-Correction Layer and Classical Control Stack of Quantum Computing Systems
Most quantum-computer security work targets physical-layer attacks on qubits, while two surfaces remain inadequately defended: the quantum-error-correction (QEC) syndrome-and-decoder pipeline, and…Accessed, never disclosed: Silent access to protected health information by medical artificial intelligence agents
Medical artificial intelligence agents should retrieve patient identifiers only when a task requires them, the data-minimization principle behind the HIPAA minimum necessary standard for protected…Malware Clustering in the Wild: Taxonomy, Challenges, and Evaluation Metrics
As malware continues to grow in volume, diversity, and sophistication, clustering has emerged as a critical technique for analyzing large malware corpora.Networked Synthetic Social Engineering on the Web
Several genuine AI services may repeat one unsupported source, and correcting that source may leave later reports unchanged.Ranked but Not Stopped: Detecting Prompt-Injection Hijacks from Typed Decision Models' Output Probabilities
Programs that use a language model as a classifier act on its most probable label.When Neither Side Confirms: Destructive Tool Approval Across MCP Servers and Hosts
LLM agents call tools that delete data or move money through the Model Context Protocol (MCP).Explicit permutations of $(\mathbb{Z}/4\mathbb{Z})^m$ with uniformly bounded differential uniformity
Symmetric primitives over Galois rings need nonlinear components whose differentials with respect to ring addition are controlled.StateFence: Task-State Protection Against Evidence-Chain Contamination in Blue-Team LLM Agents
Indirect prompt injection creates a distinctive risk for blue-team Large Language Model (LLM) agents in Security Operations Centers (SOCs).The Customer Never Sees the Goal: Measuring and Detecting Vulnerability-Targeted Manipulation in LLM Assistants
Companies deploy large language model (LLM) assistants on their websites to advise customers.Movable Antenna-Assisted Secret Key Generation over Temporally Correlated Channels
Physical-layer key generation (PLKG) exploits reciprocal channel dynamics to generate symmetric keys, addressing the key distribution problem in wireless communications.Rethinking Neural Decompilation: Candidate Selection as the Hidden Bottleneck
Reverse engineering obfuscated binaries is a core task in malware analysis and software security auditing.Do Agents Still Follow the Rules? Benchmarking Rule Compliance under Agent Context Compaction
LLM agents compact long histories to fit their context windows, but the compacted context must still carry the operating rules that govern later actions.TrafficInstruct: A Multi-Task Network Traffic Dataset and Benchmark for Instruction Tuning
Instruction tuning for multi-task network traffic analysis requires data with clearly defined sources, supervision targets, and evaluation conditions.An Empirical Evaluation of Signing and Verification Performance of Verifiable Credential Formats: A Cross-Language Benchmark of SD-JWT VC, W3C VCDM, and mdoc
We compare the signing and verification performance of three Verifiable Credential (VC) formats--SD-JWT VC; the W3C Verifiable Credentials Data Model 2.0 with a Data Integrity cryptosuite (W3C…
