近年来，使用各种平台实现了一种唯一的不可克隆芯片ID。在这篇文章中，我们研究了多态门作为一种新的机制在已经包含一些多态门的系统中实现唯一的芯片ID。所提出的解决方案利用了这样一个事实，即由于制造的不同，即使对于相同管芯上的相邻栅极，多态栅极(由Vdd控制)的开关时间也略有不同。为了在我们之前的研究中开发的可重构多态REPOMO32芯片上生成48位ID，我们应用了部分重新配置。我们获得了94.44%的稳定BITS，这与现有的方法相当接近。DOI：http://dx.doi.org/10.5755/j01.itc.42.1.925
A unique unclonable chip ID has been implemented using various platforms in the recent years. In this paper, we investigate the use of polymorphic gates as a new mechanism for implementing a unique chip ID in systems already containing some polymorphic gates. The proposed solution exploits the fact that switching time of polymorphic gates (controlled by V dd ) is slightly different even for neighboring gates on the same die because of fabrication variations. We applied a partial reconfiguration in order to generate 48-bit IDs on the reconfigurable polymorphic REPOMO32 chip that we have developed in our previous research. We achieved 94.44% stable bits which is reasonably close to existing approaches. DOI: http://dx.doi.org/10.5755/j01.itc.42.1.925
