Unclonable Identification and True Random Number Generation Based on CRO PUF

Abstract

The problem of generating true random numbers and unique identifiers is more relevant than ever in the modern digital world. This paper analyzes the bits of a binary counter acting as a number's recorder of impulses generated by the physically unclonable functions (PUF) based on a configurable ring oscillator (CRO). The results of the conducted experiments using FPGA chips and an analytical study of the PUF CRO model show the possibility of generating unique stable identifiers and true random numbers at the same time.
