A Model Stealing Attack Against Multi-Exit Networks

ICASSP 2025accepted

Compared to traditional neural networks with a single output channel, a multi-exit network has multiple exits that allow for early outputs from the model's intermediate layers, thus significantly improving computational efficiency while maintaining similar main task accuracy. Existing model stealing…

RepeatLeakage: Leak Prompts from Repeating as Large Language Model Is a Good Repeater

AAAI 2025technical

With the development of large language models (LLMs), numerous online applications based on these models have emerged. As system prompts significantly influence the performance of LLMs, many such applications conceal their system prompts and regard them as intellectual property. Consequently, numero…

DataElixir: Purifying Poisoned Dataset to Mitigate Backdoor Attacks via Diffusion Models

AAAI 2024technical

Dataset sanitization is a widely adopted proactive defense against poisoning-based backdoor attacks, aimed at filtering out and removing poisoned samples from training datasets. However, existing methods have shown limited efficacy in countering the ever-evolving trigger functions, and often leading…
