新的“安全头部”防御提高了大型语言模型对抗提示注入的鲁棒性

研究人员开发了一种名为安全头部(Heads of Security, HoS)的新型防御机制,旨在提高大型语言模型(LLM)对抗提示注入攻击的鲁棒性。HoS通过学习重新分配受信任和不受信任的token之间的注意力,使模型能够在不执行恶意指令的情况下处理外部信息。在Llama 3.3 70B Instruct和GPT OSS 20B上的评估表明,HoS在抵抗自适应攻击方面显著优于SecAlign++和ASIDE等现有防御方法,同时在效用和智能体基准测试中也保持了强大的性能。 AI

影响 这项研究引入了一种新颖的防御机制,可以显著增强LLM在实际应用中的安全性和可靠性。
