Abstract

Un combinador de division de clave criptografica, la cual incluye un numero de generadores de division de clave para generar divisiones de claves criptograficas y un aleatorizador de division de clave para aleatorizar las divisiones de claves criptograficas. Cada uno de los generadores de divisiones de claves genera divisiones de claves de los datos de siembra. Los generadores de divisiones de claves pueden incluir un generador de division aleatoria para generar una division de clave aleatoria con base en los datos de referencia. Otros generadores de divisiones de claves pueden incluir un generador de divisiones de simbolos para generar una division de simbolo con base en los datos de etiqueta, un generador de division de consola para generar una division de clave de consola con base en los datos de mantenimiento, y un generador de division biometrica para generar una division de clave biometrica con base en los datos biometricos. Ademas, todas las divisiones se pueden basar en los datos estaticos, los cuales se pueden actualizar, por ejemplo por medio de modificar un divisor del numero primo de los datos de estatica. Los datos de etiqueta se pueden leer a traves de un medio de almacenamiento, y pueden incluir los datos de autorizacion del usuario. Los datos de etiqueta pueden estar asociados con las categorias y subcategorias de etiquetas de los destinatarios, las cuales son significativas para un usuario que especifica o determina quienes se pretende que sean los receptores o el receptor de la informacion u objeto criptograficado. Una configuracion asociada con un objeto de componente del software puede usar divisiones de clave las cuales determinan cuales metodos y propiedades estan permitidos y el acceso de control a la direccion de la memoria para aquellos metodos y propiedades permitidos. La clave criptografica que resulta puede ser, por ejemplo, un flujo de simbolos, cuando menos un bloque de simbolo, o una matriz de clave.
