摘要:

Nextgeneration highsecurity cryptography and communication call for nondeterministic  generation and efficient authentication of unclonable bit sequences. Physical unclonable functions using inherent randomness in material and device fabrication process have emerged as promising candidates for realizing oneway cryptographic systems that avoid duplication and attacks. However, previous approaches suffer from the tradeoffs between lowefficiency fabrication and complicated authentication. Here, allphotonic cryptographic primitives by solution printing of organic nanolaser arrays with sizedependent dual lasing emission are reported. The stochastic distribution of organic solution into discrete capillary bridges, triggered by highrate solvent evaporation, on a periodic topographical template yields organic single crystals with regulated position, alignment, and random size, which ensures high entropy. Stimulated emission from different vibrational sublevels and the intrinsic selfabsorption effect permit sizedependent dualwavelength lasing emission at wavelengths of 660 and/or 720 nm, which can be efficiently encoded into quaternary cryptographic keys with high reliability. High entropy, solutionprocessed programming and allphotonic authentication of random organic nanolaser arrays facilitate their cryptographic implementation in secure communication with high throughput, efficiency, and low cost.
