Abstract

Generator fizycznie niekopiowalnych kluczy kryptograficznych ma układ chaotyczny (UCH), który ma dwa generatory pierścieniowe z przełączanymi ścieżkami propagacji (GPSP, GPSP'), których wyjścia (o-GPSP, o-GPSP') dołączone są do wejść (i1-DF, i2-DF) detektora fazy (DF), którego wyjście (o-DF) dołączone jest do wejść sterujących generatorów pierścieniowych z przełączanymi ścieżkami propagacji (s-GPSP, s-GPSP') przez układ sterujący (US) oraz do wyjścia (o-UCH) układu chaotycznego (UCH). Wyjście (o-UCH) układu chaotycznego (UCH) dołączone jest 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 przełączanymi ścieżkami propagacji (i-GPSP, i-GPSP') oraz do jednego wejścia układu rejestrująco-porównującego (i-URP), którego drugie wejście (z-URP) dołączone jest do wyjścia drugiego generatora pierścieniowego z przełączaną ścieżką propagacji (o-GPSP').The physically non-copyable cryptographic key generator has a chaotic system (UCH) that has two ring generators with switchable propagation paths (GPSP, GPSP ') whose outputs (o-GPSP, o-GPSP') are connected to the inputs (i1-DF, i2 -DF) phase detector (DF), whose output (o-DF) is connected to the control inputs of ring generators with switched propagation paths (s-GPSP, s-GPSP ') through the control system (US) and to the output (o-UCH ) chaotic system (UCH). The output (o-UCH) of the chaotic system (UCH) is connected to the output (o-PUF) of the generator of physically non-copyable cryptographic keys (PUF) through the registration-comparison system (URP). The generator has an input (i-UCH) connected simultaneously to the initialization inputs of ring generators with switched propagation paths (i-GPSP, i-GPSP ') and to one input of the recording-comparison system (i-URP), whose other input (z-URP ) is connected to the output of the second ring generator with switched propagation path (o-GPSP ').
