Inspired by biological diversity and uniqueness, the concept of bionic optical physical unclonable functions (PUFs) is proposed. Production is simple, low-cost, green and environmentally friendly. The extracted binary codes from bionic PUFs are random, unclonable, and robust enough for applications in entity authentication and encrypted communication.
