阅读说明：本技术 用于沿任意路径扫描物理不可克隆功能的物理签名数据的手持棒设备和方法 (Handheld wand device and method for scanning physical signature data for physically unclonable functions along arbitrary paths ) 是由 斯科特·理查德·卡斯尔 罗伯特·亨利·麦森肯斯 布兰特·丹尼斯·尼斯托姆 于 2020-03-06 设计创作，主要内容包括：通过将预磁化或后磁化颗粒模制到树脂内来创建独特的物理不可克隆功能对象。颗粒基于随机颗粒大小、位置、极性旋转、磁化水平、颗粒密度等形成独特的物理“指纹”。本发明解决的是用于准确地测量PUT的特别地包括在PUT上的足够分立的点处的磁场的X、Y和Z分量的物理指纹以允许对身份的有把握地识别的设备。描述了一种用于沿着任意路径测量磁场的手持棒。(Unique physically unclonable functional objects are created by molding pre-magnetized or post-magnetized particles into a resin. The particles form a unique physical "fingerprint" based on random particle size, location, polarity rotation, magnetization level, particle density, and the like. The present invention addresses a device for accurately measuring the physical fingerprint of the PUT, specifically comprising X, Y and the Z component of the magnetic field at sufficiently discrete points on the PUT to allow for the confident identification of an identity. A hand-held wand for measuring a magnetic field along an arbitrary path is described.)
