Tokens Change, Structure Endures: Spectral Watermarking for Generated Speech
Watermarking is a promising tool for establishing the provenance of AI-generated speech.RAISE: Reinforcing Access Control Policy Synthesis in LLMs via Symbolic Evaluation
Translating natural-language access-control requirements into policies requires careful reasoning about permissions, constraints, and exceptions, and even frontier LLMs often produce policies that…No Free Efficiency: Revisiting the Trade-off Between Training Efficiency and Model Vulnerability
Training efficiency has become the central driver of recent progress in foundation models.Training Witnesses: Trusting the Training without Trusting the Trainer
Progress in machine learning cannot outpace our ability to verify it.The Privacy Fallacy of Crowdsourced Fine-Tuning: Extracting Proprietary Data via Topic-Based Poisoning
Supervised fine-tuning (SFT) is widely used to adapt large language models to downstream tasks.GenoTrace: Inheritable Watermarks for Genome Foundation Model Distillation
Can a genome model retain a detectable record of the synthetic sequences used to train it?GenomeOcean Anywhere: Private WebGPU Inference for Genome MoEs
Genome foundation models are most useful where sequences are generated, yet the largest models need datacenter accelerators and a place to send private DNA.CipherGenome: Homomorphic Inference for Genomic Mixture-of-Experts
Genome foundation models are growing into sparse mixture-of-experts (MoE) networks whose expert weights no longer fit on the machines that hold the sequences, yet sending a private genome to rented…Agentic Commerce Bench: Measuring Fraud Detection for Agents That Spend Money
AI agents now hold spend authority and settle payments without per-action human confirmation.Dual-Fit Imperative in Security Leadership: A Grounded Theory Investigation of CISO Role Enactment in Modern Organisations
The Chief Information Security Officer (CISO) has emerged as a strategically prominent executive role, confronting an adversarial environment, irreconcilable accountability tensions between security…SINGED: Correct Outputs Do Not Certify Safe Execution in LLM Agents
Tool-using language-model agents select and execute third-party artifacts.Checking Leakage Witnesses versus Certifying Bounded Non-Leakage
When a language-model audit finds no leak, what is needed to certify non-leakage?DegreeSpar: Structured Degree Sparsity for Efficient Secure Transformer Inference
Secure Transformer inference protects sensitive inputs but incurs substantial cryptographic overhead, with nonlinear operations such as Softmax and GeLU becoming major bottlenecks.Residual Transferability in Neural Image Watermarking
Neural image watermarks can be forged by extracting watermark-bearing residuals from released images and transferring them to unrelated content.Black-Box Auditing of Epistemic Reliability in Multi-Agent Debate Distillation
Debate distillation adapts weaker verifiers using multi-agent debate transcripts to improve their judgement in subsequent debates, but gains on monitored tasks do not establish reliability on…Reward Hacking and Agent Containment Failure: A Monte Carlo Study Based on the 2026 Hugging Face Incident
The July 2026 intrusion into Hugging Face production infrastructure showed how reward hacking can become an external cybersecurity incident when a capable agent encounters weak containment boundaries.SkillDRE: Dual-Stage Red-Team Evolution of Agent Skills via Pre-Execution and Runtime Feedback
Agent skills package instructions, executable code, and task-specific resources into reusable artifacts that agents can improve using execution feedback.CyberClear: A Benchmark for LLM Agent Systems on APT Attack Chain Provenance
Large language model agents have demonstrated promising capabilities in cybersecurity tasks, yet their ability to reconstruct complete Advanced Persistent Threat attack campaigns from complex…Hearsay: Can an Auditor Trust the Record a Deployed Agent Harness Writes?
An agent harness, the code that turns a model into an agent, writes its own record of each run, and that record is all a later reader gets when a run is disputed, investigated or audited.REFINE: A Resilient Evolution Framework for Intelligent Enterprise Alert Triage in Security Operations Centers
Security Operations Centers (SOCs) process large volumes of alerts daily.
