镧系元素（III）离子掺杂的沸石的随机图案用于创建防篡改光学认证系统。安全数据加密严重依赖于单向函数，而复制保护依赖于难以复制的功能。提出了一种基于物理单向函数或物理不可克隆函数（PUF）的镧系发光的光学认证系统。它们不能被复制，因此能够实现牢不可破的加密。此外，如果将具有唯一PUF的标签嫁接到产品上，则PUF将防止伪造。我们已经开发了一个认证系统，包括一个硬件阅读器，图像分析，认证软件和物理密钥，我们证明作为一个防伪系统。物理密钥是由玻璃上的聚合物膜中的标签剂的随机图案制成的PUF，其可以在掺杂到各个标签剂中的特定镧系元素（III）离子的选择性激发之后成像。这种形式的激发选择成像确保通过使用至少两种镧系元素（III）离子掺杂剂，随机图案不能被复制，因为当使用任何其他发射体时激发选择将失败。使用开发的读取器和软件，随机图案被读取和数字化，这允许存储数字图案。该数字图案或数字密钥可用于防伪中的物理密钥认证或任何消息的加密。产生的PUF密钥的名义编码容量高达73600。虽然所实现的认证系统的编码容量减少到6 × 10104，但它足以完全防止产品的伪造。
Random patterns of lanthanide(III) ion–doped zeolites were used to create a tamper-proof optical authentication system. Secure data encryption relies heavily on one-way functions, and copy protection relies on features that are difficult to reproduce. We present an optical authentication system based on lanthanide luminescence from physical one-way functions or physical unclonable functions (PUFs). They cannot be reproduced and thus enable unbreakable encryption. Further, PUFs will prevent counterfeiting if tags with unique PUFs are grafted onto products. We have developed an authentication system that comprises a hardware reader, image analysis, and authentication software and physical keys that we demonstrate as an anticounterfeiting system. The physical keys are PUFs made from random patterns of taggants in polymer films on glass that can be imaged following selected excitation of particular lanthanide(III) ions doped into the individual taggants. This form of excitation-selected imaging ensures that by using at least two lanthanide(III) ion dopants, the random patterns cannot be copied, because the excitation selection will fail when using any other emitter. With the developed reader and software, the random patterns are read and digitized, which allows a digital pattern to be stored. This digital pattern or digital key can be used to authenticate the physical key in anticounterfeiting or to encrypt any message. The PUF key was produced with a staggering nominal encoding capacity of 73600. Although the encoding capacity of the realized authentication system reduces to 6 × 10104, it is more than sufficient to completely preclude counterfeiting of products.
