Abstract
A method for defending an LLM against a jailbreaking attack includes receiving an input prompt for generating output from the LLM. The method further includes generating N versions of the input prompt, wherein generating each of the N versions includes perturbing the input prompt to generate N perturbed input prompts. The method further includes providing the N perturbed input prompts as input to the LLM, which generates N responses. The method further includes aggregating the responses by estimating a group effect of the perturbed input prompts on the LLM. The method further includes selecting, as output, one of the N responses corresponding to a perturbed input prompt that causes the LLM to generate a response that agrees with the estimated group effect.
