DeepSeek Robustness Against Semantic-Character Dual-Space Mutated Prompt Injection
The paper introduces PromptFuzz-SC, a novel semantic-character dual-space mutation framework, demonstrating that combining both semantic and character-level attacks significantly improves the robustness evaluation of LLMs like DeepSeek against prompt injection.
