The majority of machine learning methodologies operate with the assumption that their environment is benign. However, this assumption does not always hold, as it is often advantageous to adversaries to maliciously modify the training (poisoning attacks) or test data (evasion attacks). Such attacks can be catastrophic given the growth and the penetration of machine learning applications in society. Therefore, there is a need to secure machine learning enabling the safe adoption of it in adversarial cases, such as spam filtering, malware detection, and biometric recognition. This paper presents a taxonomy and survey of attacks against systems that use machine learning. It organizes the body of knowledge in adversarial machine learning so as to identify the aspects where researchers from different fields can contribute to. The taxonomy identifies attacks which share key characteristics and as such can potentially be addressed by the same defence approaches. Thus, the proposed taxonomy makes it easier to understand the existing attack landscape towards developing defence mechanisms, which are not investigated in this survey. The taxonomy is also leveraged to identify open problems that can lead to new research areas within the field of adversarial machine learning. 相似文献

侧信道攻击是一种强有力的物理安全分析方法,密码芯片侧信道攻击的安全评估一般都是在生产后期进行的,但生产后期进行侧信道攻击安全评估具有费时、容易出错及费用高昂等缺陷。为了提高效率,有必要在设计阶段进行侧信道攻击安全评估,这需相应的侧信道仿真工具支持。针对侧信道攻击需要相应的侧信道仿真工具支持的特点,提出一种侧信道攻击仿真环境的设计方案。该方案采用软硬件协同设计的思想,通过泄露仿真机制和安全分析策略相分离的方法,用构件技术来建立侧信道攻击的仿真环境,能在密码芯片的设计阶段对侧信道攻击进行仿真分析。与现有的PINPAS仿真环境相比,该环境具有灵活、高效的特点。 相似文献

In this paper, the synchronization of complex dynamical networks (CDNs) under ‘successful’ but recoverable attacks is studied by utilizing the framework of switching systems. ‘Successful’ attacks refer to a class of attacks that break a network into a group of isolated clusters. Recoverable attacks refer to a class of attacks that the network can recover from after a period of time. To facilitate the investigation of the synchronization of a CDN under ‘successful’ but recoverable attacks, the attack frequency and the average recovering time are introduced. By using a piecewise Lyapunov function, the upper bounds of the attack frequency and the average recovering time are obtained to ensure that the whole network can achieve global synchronization under attacks. 相似文献
