All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security
Advanced Materials, EarlyView.An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Error probability and error stream properties in channel with slow Rician fading
Journal of Telecommunications and Information Technology, 2003 In a radio communication channel wave parameters fluctuate randomly. The signal envelope undergoes deep fades. When binary information is transmitted through such a channel, fading causes random variation of probabilities of error associated with the ...

Modeling Application-Level Soft Error Effects for Single-Event Multi-Bit Upsets
IEEE Access, 2019 Transient errors induced by radiations cause bit-flips in flip-flops (flip-flop soft errors). Modeling the error resilience level of a target system for flip-flop soft errors is a crucial step to achieve a cost-effective error resilience solution.
