    Llama3.1-8B-Instruct, Gemma-7B-Instruct, Qwen2.5-7B-Instruct and others9
    AbstractReSA 用最大熵 IRL 从对齐模型行为恢复代理安全奖励,并在解码时反转以诱导有害输出。

    ReSA 是一种对抗攻击:从对齐模型的可观察行为恢复代理安全奖励,再在解码时把该奖励反过来用。。

    CGMIA:用成员推理攻击检测代码生成基准的数据泄漏

    提出 CGMIA,检测代码生成基准样本是否泄漏进训练集

    Published
    Attacker
    Gray-box
    Evaluated models
    Qwen2.5-Coder (3B), CodeGemma (2B), DeepSeek-Coder (1.3B) and others5
    AbstractCGMIA 融合相似度、通过率、困惑度与 CodeBERT,在模拟泄漏上优于八个 MIA 基线。

    CGMIA 用成员推断检测代码生成基准是否泄入 LLM 训练集,使评测不依赖对训练语料的直接访问。

    研究提出 Q-Skew:利用 token 级记忆不对称对微调扩散语言模型做成员推断

    提出 Q-SKEW,利用 token 级记忆不对称推断微调扩散语言模型的成员

    Published
    Attacker
    Gray-box
    Evaluated models
    LLaDA-8B-Base, LLaDA-8B-Instruct, Dream-Base-7B and others4
    AbstractQ-SKEW 用 token 损失差的右偏区分微调 DLM 成员,并可辅助 PII 排序。

    Q-SKEW 是针对微调扩散语言模型的 gray-box 成员推断指标,依据是 token 记忆增益随掩码率下降而增大、成员序列因此右偏。。
