In the vanguard of safeguarding data integrity, optical encryption and anti-counterfeiting measures are indispensable. Structural color, with its inherent optical exclusivity, including tunable chromaticity and intricate high-resolution patterning, stands at the forefront of this domain. Despite its promise, the proliferation of structural color technologies in anti-counterfeiting applications is curtailed by the exorbitant production costs and the current limitations in information capacity and security. Addressing these constraints, our study delineates a novel encryption paradigm that interlaces color and digital data within a subwavelength grating matrix. This synergy is fortified by a tri-layered encryption schema, amalgamating electrical response signatures, inherent optical attributes, and the robust RSA algorithm, thereby elevating the information capacity exponentially to 10 and reinforcing multi-faceted security throughout transmission. Our approach heralds a new era in the realm of high density, secure information storage.
在保障数据完整性的前沿领域，光学加密和防伪措施不可或缺。结构色凭借其固有的光学独特性，包括可调节的色度和复杂的高分辨率图案，处于该领域的前沿。尽管前景广阔，但结构色技术在防伪应用中的推广受到高昂生产成本以及当前信息容量和安全性限制的阻碍。为解决这些限制，我们的研究描绘了一种新颖的加密范式，该范式在亚波长光栅矩阵中交织颜色和数字数据。这种协同作用通过三层加密架构得到加强，融合了电响应特征、固有光学属性和强大的RSA算法，从而将信息容量呈指数级提升至10，并在整个传输过程中增强多方面的安全性。我们的方法开创了高密度、安全信息存储领域的新纪元。
