Optical physical unclonable functions (PUFs) have been widely acknowledged as a desirable means in response to the increasingly severe challenges of information security owing to their noncontact attributes and nonlinear response. Currently, dynamic PUFs, based on fluorescent and reconfigurable PUFs, face challenges such as wide line width affecting authentication accuracy and limitations in application scenarios due to intrinsic changes in the samples. Herein, leveraging the narrow line width characteristics of lasers and the high concealment of polarization regulation, we fabricated randomly oriented perovskite microspheres and realized dynamic PUFs by modulating the polarization directions. A discussion of the properties demonstrates that the proposed PUFs exhibit a notable level of uniformity, uniqueness, and robustness regardless of whether the substrate is rigid or flexible. The proposed dynamic PUFs relying on polarization offer a novel approach to implementing dynamic PUFs, thereby fostering the advancement of high-security anticounterfeiting authentication.

依赖激光偏振的动态物理不可克隆功能
光学物理不可克隆函数(PUF)因其非接触属性和非线性响应而被广泛认为是应对日益严峻的信息安全挑战的理想手段。目前,基于荧光PUF和可重构PUF的动态PUF面临着线宽过宽影响认证精度以及样本内在变化导致应用场景受限等挑战。在此,我们利用激光的窄线宽特性和偏振调节的高隐蔽性,制备了随机取向的钙钛矿微球,并通过调制偏振方向实现了动态PUF。对这些特性的讨论表明,无论基材是刚性的还是柔性的,所提出的 PUF 都表现出显着的均匀性、独特性和鲁棒性。所提出的依赖于极化的动态PUF提供了一种实现动态PUF的新方法,从而促进了高安全性防伪认证的进步。
