我们设计了一种新的基于聚类的感染节点选择算法,以进一步减少所需的攻击预算。 Yu Sheng, Rong Chen, Guanyu Cai, and Li Kuang. 2021. Backdoor attack of graph neural networks based on subgraph trigger. In International Conference on Collaborative Computing: Networking, Applications and Worksharing. Springe...
这里只谈及了将具有trigger的输入误分类,而对于没有backdoor trigger的输入而言,该模型会按照其原本的label进行分类,换句话说,backdoor不会影响那些不具有触发器的输入数据的分类结果。这是backdoor attacks的一大特点。 问题的提出 问题提出的背景: backdoor attack属于poisoning attack的一种形式。这类攻击对于模型自身...

security. It has armed guards at the front door, sophisticated locking mechanisms and biometric access controls that make it impossible to access without proper authorization. However, a backdoor that bypasses these measures, such as a large ventilation shaft, makes the vault vulnerable to attack. ...
What is a backdoor attack? A backdoor attack is a clandestine method of sidestepping normal authentication procedures to gain unauthorized access to a system. Typically, executing a backdoor attack involves exploiting system weaknesses or installing malicious software that creates an entry point for ...
a major security threat to deep learning. A backdoor attack implants a backdoor trigger into a target model via data poisoning so as to control the model’s predictions at test time. Different from image classification models on which most of existing backdoor attacks have been developed and ...
Look, Listen, and Attack: Backdoor Attacks Against Video Action Recognitionarxiv.org/abs/2301.00986 目前文章尚未开源,但整体的结构比较清晰,可以先存着。 Abstract 深度神经网络(dnn)容易受到一种称为“后门攻击”的攻击,这种攻击会在后门触发器和攻击者感兴趣的目标标签之间建立联系。后门DNN在干净的测试图...
何为后门攻击(Backdoor attack、Trojan attack特洛伊木马攻击) 在针对强化学习的后门攻击中,用户会使用攻击者事先训练好的带有后门的策略网络。 在攻击者没有触发后门时,智能体的的表现出正常的行为,直到它被触发。当攻击者触发了网络中的后门时,智能体会表现出异常的行为。例如,在自动驾驶汽车的案例中,汽车在大多数...
hidden trigger backdoor attack 贡献:一种新颖的干净标签后门攻击方法,该方法在特征空间中优化与目标图像接近的有毒图像,以增加不可见性;讨论了动态后门攻击。 方法:以良性样本训练;产生干净标签的投毒样本;使用生成的中毒样本和良性样本微调模型。 3)Optimized Attacks: ...
