Here, we report crystallization\u2010driven helical CP nanowires (NWs) that enable circularly polarized light (CPL)\u2013addressable ferroelectric physically unclonable functions (PUFs).

We demonstrate that the PMMA corona of the NWs mediates the interfacial interaction with the ferroelectric matrix, transcribing supramolecular helicity into helicity\u2010dependent remanent polarization, establishing handedness\u2010selective polarization landscapes under CPL excitation. These stochastic spatial polarization states serve as robust multiscale entropy sources, yielding 256\u2010bit identifiers with near\u2010ideal bit uniformity (\u223c0.5) and inter\u2010device Hamming distance distributions (\u223c0.4). By stabilizing supramolecular chirality as remanent polarization within an interpenetrated hybrid network, this work establishes a hybrid optoelectric PUF platform that significantly expands the dimension of secure encoding in soft polymer electronics.\n
