随着先进物理克隆和网络窃取技术的 proliferate，实现绝对硬件级信息安全已成为全球性的重大挑战。传统架构系统从根本上存在脆弱性，因为确定性存储和加密硬件在物理上是分离的，使敏感数据暴露于截获风险。虽然物理不可克隆函数（PUFs）提供稳健的认证，但将其与高密度数据写入集成在统一的纳米尺度介质中仍难以实现。在此，我们提出一种内在安全的一体化架构，将高维数据编码与多尺度物理加密不可分割地融合在单个纳米金刚石（NDs）中。通过精确的聚焦电子束辐照，我们实现了单纳米颗粒缺陷工程，能够在单个NDs内进行确定性的36进制数据写入。关键的是，这一定制存储层被永久锁定在介质固有的随机性中，将宏观空间PUFs与通过光探测磁共振（ODMR）提取的严格不可复制的原子尺度量子指纹相结合。通过将确定性存储无缝嵌入不可克隆的物理环境，我们的方法从根本上消除了分离硬件的脆弱性，为防篡改存储芯片、零信任网络和下一代数据保险库提供了无条件安全的固态基础。
英文摘要
As advanced physical cloning and cyber-extraction techniques proliferate, achieving absolute hardware-level information security has become a paramount global challenge. Conventional architectures systems are fundamentally vulnerable because deterministic memory and cryptographic hardware are physically decoupled, exposing sensitive data to interception. While physical unclonable functions (PUFs) offer robust authentication, integrating them with high-density data writing within a unified nanoscale medium remains elusive. Here, we present an intrinsically secure all-in-one architecture that inextricably fuses high-dimensional data encoding with multiscale physical encryption within single nanodiamonds (NDs). Through precise focused-electron-beam irradiation, we achieve single-nanoparticle defect engineering, enabling deterministic base-36 data writing within individual NDs. Crucially, this customized memory layer is permanently locked within the medium's inherent stochasticity, combining macroscopic spatial PUFs with strictly irreproducible atomic-scale quantum fingerprints extracted via optically detected magnetic resonance (ODMR). By seamlessly embedding deterministic memory into an unclonable physical environment, our approach intrinsically eliminates the vulnerabilities of separated hardware, providing an unconditionally secure solid-state foundation for tamper-proof memory chips, zero-trust networks and next-generation data vaults.
