随着增材制造（AM）变得越来越普遍，其供应链转向严重依赖云资源的分布式商业模式。尽管这种模式有无数好处，但它引起了人们对全球化进程可信度的严重关切，因为存在着几类可能破坏其安全保障的网络安全攻击。在这项工作中，我们专注于3D设计的知识产权（IP）的保护，并介绍了混淆CADe，这是一种新的保护方法，防止伪造，通过嵌入特殊功能的CAD模型。引入的特征干扰设计的完整性，有效地将高质量制造限制到仅一组独特的处理设置和条件;在所有其他条件下，打印的工件遭受质量差、过早失效和/或故障。
As additive manufacturing (AM) becomes more pervasive, its supply chains shift towards distributed business models that heavily rely on cloud resources. Despite its countless benefits, this paradigm raises significant concerns about the trustworthiness of the globalized process, as there exist several classes of cybersecurity attacks that can undermine its security guarantees. In this work, we focus on the protection of the intellectual property (IP) of 3D designs, and introduce ObfusCADe, which is a novel protection method against counterfeiting, by embedding special features in CAD models. The introduced features interfere with the integrity of the design, effectively restricting high quality manufacturing to only a unique set of processing settings and conditions; under all other conditions, the printed artifact suffers from poor quality, premature failures and/or malfunctions.
