Abstract

La presente invención se refiere a una autoridad de dominio 13 para el uso en una jerarquía de autoridades de dominio en un sistema criptográfico jerárquico. La autoridad de dominio 13 comprende un generador de claves secretas de usuario 21 para generar una clave secreta de usuario basada en una clave secreta de dominio y una o más representaciones de atributos, para obtener una clave secreta de usuario asociada con un conjunto de atributos que corresponden a las representaciones de atributos y en donde la clave secreta de dominio se basa en una clave secreta de dominio de una autoridad de dominio de origen o una clave secreta de raíz de una autoridad de raíz de la jerarquía de autoridades de dominio y en donde las representaciones de atributos son independientes de la jerarquía. Un descifrador hace uso de la clave secreta de usuario. Un cifrador genera un texto cifrado que es descifrable por el descifrador.
