Mathematical Impossibility of Perfect Prompt Injection Defense in Shared-Embedding LLMs
Researchers prove that in shared-embedding sequence models without enforced control-data separation, perfect prevention of prompt injection attacks is mathematically impossible. This explains why all current defenses against prompt injection in LLM-integrated applications have been broken.
Prompt injection is the top security risk for applications using large language models, and this finding highlights a fundamental architectural vulnerability. Understanding this limitation is crucial for developing more secure AI systems or alternative architectures.
