Information security serves as the cornerstone for ensuring stable development of today’s highly digitized era. As cryptographic primitives with high and robust encryption capabilities, physical unclonable functions (PUFs) are recognized one critical solutions to address information leakage issues. However, encoding PUFs often relies on inherent properties materials, which limits potential further enhancement their capacity (EC). In this study, we introduce a four-level scheme by leveraging stochastic characteristics free radical chemical reactions energy deposition in fabrication process silicon carbide (SiC) color centers. A multilevel multimodal PUF (MMPUF) strategy (ES) flexible substrates EC, low cost, simple fast readout was constructed. The spatially random distribution SiC vacancy (Vsi) color-center concentrations well offsets laser pyrolysis position along X- Y-axes four independent that ensure performance PUF, achieving 24×10×10 secure, stable, encoding. Furthermore, integration tags products through doping manufacturing process, rather than attachment, enhances practicality anti-counterfeiting system. proposed hierarchy based provides novel solution improving EC.
