论文摘要
物理上无统治的功能（PUF）是一种嵌入式硬件安全措施，可提供防止伪造的保护。在这里，我们介绍了使用一系列随机磁化的微米大小的铁磁条（Micromagnets）作为PUF的工作。我们采用钻石中氮呈（NV）中心的4 $ $ m厚的表面层来对阵列中每个微型磁体的磁场进行成像，然后使用图像分析技术提取每个微型网络的磁极性。在评估了Micromagnet阵列PUF的随机性和NV读数的敏感性之后，我们通过讨论可能提高安全性和磁性读数的未来增强功能来得出结论。
A physically unclonable function (PUF) is an embedded hardware security measure that provides protection against counterfeiting. Here we present our work on using an array of randomly-magnetized micron-sized ferromagnetic bars (micromagnets) as a PUF. We employ a 4 $μ$m thick surface layer of nitrogen-vacancy (NV) centers in diamond to image the magnetic fields from each micromagnet in the array, after which we extract the magnetic polarity of each micromagnet using image analysis techniques. After evaluating the randomness of the micromagnet array PUF and the sensitivity of the NV readout, we conclude by discussing the possible future enhancements for improved security and magnetic readout.
