Abstract

Generator fizycznie niekopiowalnych kluczy kryptograficznych zawiera generator pierścieniowy z regulowaną szybkością (GPRS), który zawiera klucz startowy (KS) i linię opóźniającą (LO) zawierającą elementy opóźniające połączone w szereg (EO). Wyjście (o-LO) linii opóźniającej (LO) jest dołączone do wyjścia (o-GPRS) generatora z regulowaną szybkością (GPRS), a także do jej wejścia (i-LO) przez klucz startowy (KS), którego wejście sterujące dołączone jest do wejścia inicjalizacji generatora (i-GPRS). W linię opóźniającą (LO) włączony został szeregowo przynajmniej jeden sterowany element opóźniający (T), zaś wejście sterujące (S-T) sterowanego elementu opóźniającego (T) dołączone jest do wejścia sterującego (s-GPRS) generatora pierścieniowego z regulowaną szybkością (GPRS).The physically non-copyable cryptographic key generator includes a Rate Variable Rate (GPRS) ring generator that includes a start key (KS) and a delay line (LO) containing series-connected delay (EO) elements. The (o-LO) delay line (LO) output is connected to the output (o-GPRS) of the variable speed generator (GPRS) as well as to its input (i-LO) through the start key (KS) whose control input is connected to the generator initialization input (i-GPRS). At least one controllable delay element (T) is serially connected to the delay line (LO), and a control input (S-T) of the controlled delay element (T) is connected to the control input (s-GPRS) of the variable speed ring generator (GPRS).
