论文摘要
安全是许多应用程序集成电路设计的重要方面。随着高级节点的电路制造几乎不可避免地依赖于不受信任的铸造厂，IP隐私和特洛伊木马的插入正在增长威胁。提出的解决方案是使用碎屑混淆，它使用了一个可信赖和不信任的IC制造方案。通过利用两个CMOS流程，系统将获得可信赖的遗产节点的更强安全保证，同时还利用了高级不信任节点的性能和密度。对分裂芯片混淆的有效性至关重要的是发现两个IC之间的系统的最佳分区。在本文中，我们为拆分芯片混淆方案开发了一个设计流，定义了基本系统指标，并创建了一种快速评估大型设计空间的工具。我们演示了这种工具的概念，并将其应用于示例SOC。
Security is an important facet of integrated circuit design for many applications. IP privacy and Trojan insertion are growing threats as circuit fabrication in advanced nodes almost inevitably relies on untrusted foundries. A proposed solution is Split-Chip Obfuscation that uses a combination trusted and untrusted IC fabrication scheme. By utilizing two CMOS processes, a system is endowed with the stronger security guaranties of a trusted legacy node while also leveraging the performance and density of an advanced untrusted node. Critical to the effectiveness of Split-Chip Obfuscation is finding an optimum partitioning of a system between the two ICs. In this paper, we develop a design flow for the Split-Chip Obfuscation scheme, defining the essential system metrics and creating a tool to rapidly assess the large design space. We demonstrate the concept of such a tool and show its application on an example SoC.
