Conversation Reconstruction Attack Against GPT Models

In recent times, significant advancements have been made in the field of large language models (LLMs), represented by GPT series models. To optimize task execution, users often engage in multi-round conversations with GPT models hosted in cloud environments. These multi-round conversations, potentially replete with private information, require transmission and storage within the cloud. However, this operational paradigm introduces additional attack surfaces. In this paper, we first introduce a specific Conversation Reconstruction Attack targeting GPT models. Our introduced Conversation Reconstruction Attack …
