Abstract

A találmány tárgya eljárás tartalmat hordozó digitális adatoknak egyforrásból (1, 10) digitális távközlési csatornán át egy vevőhöz (2,12) továbbítására, amely digitális adatokat legalább egy vezérlőszóval (CW) összezavarják. A forrásban (1, 10) a következő lépésekethajtják végre: (a) a forrás (1, 10) által átmenetileg tárolt efemerkódoló kulcsot (KCW, R) állítanak elő, (b) a vezérlő szót (CW) ezenkódoló kulcs (KCW, R) felhasználásával kódolják, (c) a vevőhöz (2, 12)továbbítják - az összekevert digitális adagokat és - a kódolt vezérlőszót (CW), amely utóbbit a forrás (1, 10) és a vevő (2, 12) közöttkódolt távközlési csatornán (21) át továbbítják, (d) a vevő (2, 12)által kezdeményezett és a forrás (1, 10) hitelesítésére irányulóműveletére (22) válaszolnak és ha a forrást (1, 10) a vevő (2, 12)hitelesíti, akkor a kódoló kulcsot (KCW, R) továbbítják a vevőhöz (2,12), (e) törlik a kódoló kulcsot (KCW, R). A találmány tárgya továbbáeljárás tartalmat hordozó digitális adatoknak egy forrásból (1, 10)digitális távközlési csatornán át egy vevőhöz (2, 12) továbbítására,amely digitális adatokat legalább egy vezérlő szóval (CW)összezavarják. A vevőben (2, 12) a következő lépéseket hajtják végre:(i) fogadják az összekevert digitális adatokat (j) fogadják egy kódolókulcs (KCW, R) felhasználásával kódolt vezérlő szót (CW) , amelyet aforrás (1, 10) és a vevő (2, 12) között kódolt távközlési csatornán(21) át továbbítanak, (k) a forrást (1, 10) hitelesítő műveletet (22)hajtanak végre és ha a vevő (2, 12) hitelesíti a forrást (1, 10),akkor - veszik és átmenetileg tárolják a kódoló kulcsot (KCW, R) - akódoló kulcs (KCW, R) segítségével dekódolják a vezérlő szót (CW), - adekódolt vezérlő szó (CW) segítségével a digitális adatokathelyreállítva azokat felhasználó számára bemutatható jellé alakítjákát, és - törlik a kódoló kulcsot (KCW, R).
