Entropy Distribution as a Fingerprint for Hallucinations in Generative Models

Researchers propose Calibrated Entropy Score (CES), a novel method for detecting hallucinations in large language models using entropy distribution patterns from a single forward pass. The technique achieves performance comparable to computationally expensive multi-sample methods while requiring only black-box access to token logits, with formal mathematical guarantees for detection accuracy.

DualSentinel: A Lightweight Framework for Detecting Targeted Attacks in Black-box LLM via Dual Entropy Lull Pattern

Researchers introduce DualSentinel, a lightweight framework for detecting targeted attacks on Large Language Models by identifying 'Entropy Lull' patterns - periods of abnormally low token probability entropy that indicate when LLMs are being coercively controlled. The system uses dual-check verification to accurately detect backdoor and prompt injection attacks with near-zero false positives while maintaining minimal computational overhead.
