Hierarchical Physically Unclonable Functions From CVD‐Grown Two‐Dimensional High‐Entropy Spinel Oxide Nanoflakes

Physically unclonable functions (PUFs) provide hardware‐rooted security by converting intrinsic material randomness into unique cryptographic fingerprints. However, most existing PUF systems rely on a single entropy source, limiting key capacity and adaptability for hierarchical authentication. Here, we report a hierar...
