LLM Defense Framework

A comprehensive framework for enhancing LLM security through post-processing defenses and statistical guarantees.

Overview

This project implements a novel approach to LLM security focusing on:

• Post-processing defense mechanisms
• Statistical guarantees through one-class SVM
• Adaptive policy updates
• Multimodal security evaluation

Components

1. Sampling Methods

• Speculative decoding optimization
• Tree-based sampling
• Nucleus sampling with guarantees

2. Defense Mechanisms

• Content filtering with statistical guarantees
• Policy adaptation framework
• Real-time verification

3. Evaluation Framework

• Comprehensive security benchmarks
• Performance metrics
• Statistical validation
