Abstract

A találmány szerinti kriptorendszerben (1) rendszerparaméterek egyhalmazát hozzák létre; (2) letéti hatóságok útján kriptográfiaikulcsokat generálnak, és a letéti hatósági nyilvános kulcsokatközzéteszik; (3) egyedi tanúsító hatósági paramétereket tesznek közzéaz egyes tanúsító hatóságok útján; (4) az említett rendszerparaméterekalapján egy felhasználói algoritmussal egy nyilvános/titkos kulcspártgenerálnak mindegyik felhasználónál; (5) egy bizonyítékot generálnakmindegyik felhasználónál arról, hogy a felhasználó nyilvános/titkoskulcspárját az említett felhasználói algoritmussal generálták, és hogyaz említett felhasználó titkos kulcsa visszaállítható a letétihatóságok által; (6) egy tanúsító hatóság útján ellenőrzik az említettbizonyíték érvényességét; (7) egy tanúsító hatóság útján hitelesítikaz említett felhasználó nyilvános kulcsát, és ha a bizonyítékérvényes, erről egy nyilvánosan elérhető tanúsítványt készítenek; és(8) miközben a kriptorendszer felhasználói alkalmazzák a felhasználóikulcsokat és tanúsítványokat, (9) megfelelő felhatalmazás esetén aletéti hatóságok útján visszaállítják egy felhasználó titkos kulcsátvagy az említett titkos kulcsnak megfelelő nyilvános kulccsaltitkosított információt.
