Hardware‐Intrinsic Encryption Using Spectrally Multiplexed Nitrogen Vacancy Spin Ensembles in Nanodiamonds
Secure encryption lies at the heart of data protection across virtually every sector of modern society. Physical unclonable functions (PUFs) provide an indispensable root of trust for ensuring this security. However, existing PUFs remain limited by two key constraints: a trade‐off between cryptographic capacity and...
