Enhancing LLM-Based Vulnerability Detection via Representation-Aware Logical Ensemble

Automated vulnerability detection in C source code is a long-standing challenge, as traditional static analysis tools often trade precision for scalability and struggle with complex vulnerability patterns. Recently, large language models (LLMs) have shown promising results; yet, most approaches rely on a single code re...

What is the Difference Between Me and You? Benchmarking the Quality Gap Between Human-Written and AI-Generated Code

This work compares human-written and AI-generated code at scale, characterize structural complexity and statistical naturalness, and map static-analysis findings onto Orthogonal Defect Classification for defects and the Common Weakness Enumeration for vulnerabilities, making authors and languages directly comparable.

Beyond Fixed Fault Models: Comparing LLM-Based and Rule-Based Fault Injection in OpenStack

It is shown that LLM-based fault injection extends the behavioral coverage of fixed fault models without establishing general superiority, and that practical adoption still requires controlled generation, runtime validation, system-level oracles, and reproducible experimental provenance.
