Boa: First System to Solve LLM Jailbreak Oracle Problem
Researchers have introduced the jailbreak oracle problem, a formalization to assess LLM vulnerability to jailbreak attacks by determining whether a response exceeding a specified likelihood threshold can be generated. Solving this problem is computationally challenging due to exponential search space growth. They present Boa, the first system designed to efficiently solve the jailbreak oracle problem using a two-phase search strategy: breadth-first sampling to identify easily accessible jailbreaks, followed by depth-first priority search guided by fine-grained safety scores. This work addresses a critical security gap as LLMs are increasingly deployed in safety-critical applications.
