Abstract

Generator fizycznie niekopiowalnych kluczy kryptograficznych ma dwa generatory pierścieniowe z regulowaną szybkością (GPRS, GPRS'), których wyjścia (o-GPRS, o-GPRS') dołączone są do wejść (i1-DF, i2-DF) detektora fazy (DF), którego wyjście (o-DF) dołączone jest do wejść sterujących generatorów pierścieniowych z regulowaną szybkością (s-GPRS, s-GPRS') przez układ sterujący (US) oraz do wyjścia (o-PUF) generatora fizycznie niekopiowalnych kluczy kryptograficznych (PUF) przez układ rejestrująco-porównujący (URP). Generator ma wejście (i-UCH) dołączone jednocześnie do wejść inicjalizujących generatorów pierścieniowych z regulowaną szybkością (i-GPRS, i-GPRS') oraz do jednego wejścia układu rejestrująco-porównującego (i-URP), którego drugie wejście (z-URP) dołączone jest do wyjścia drugiego generatora pierścieniowego z regulowaną szybkością (o-GPRS').The physically non-copyable cryptographic key generator has two adjustable speed ring generators (GPRS, GPRS ') whose outputs (o-GPRS, o-GPRS') are connected to the inputs (i1-DF, i2-DF) of the phase detector (DF), whose output (o-DF) is connected to the control inputs of adjustable speed ring generators (s-GPRS, s-GPRS ') through the control system (US) and to the output (o-PUF) of the physically non-copyable cryptographic keys (PUF) by recording and comparison system (URP). The generator has an input (i-UCH) connected simultaneously to the initialization inputs of adjustable-speed ring generators (i-GPRS, i-GPRS ') and to one input of the recording-comparison system (i-URP), whose other input (z-URP) it is connected to the output of a second ring generator with adjustable speed (o-GPRS ').
