Abstract

EN ESTE DOCUMENTO SE DESCRIBEN MÉTODOS, SISTEMAS, Y DISPOSITIVOS PARA ENTREGAR DATOS PROTEGIDOS A UN ENTORNO DE EJECUCIÓN CONFIABLE (TREE) ANIDADO, QUE INCLUYE UN TRUSTLET EJECUTÁNDOSE SOBRE KERNEL SEGURO, ASOCIADO CON UN SOLICITANTE POTENCIALMENTE NO CONFIABLE. EN UN ASPECTO, UNA CABEZA DE PROTOCOLO DE DIRECCIONAMIENTO, U OTRO INTERMEDIARIO ENTRE UN SOLICITANTE Y UN SISTEMA DE GESTIÓN DE CLAVES U OTRO ALMACÉN DE DATOS PROTEGIDOS, PUEDE RECIBIR UNA SOLICITUD DE DATOS PROTEGIDOS DE UN SOLICITANTE POTENCIALMENTE NO CONFIABLE, Y UNA DECLARACIÓN DE AFIRMACIÓN DEL KERNEL SEGURO. LA CABEZA DE PROTOCOLO DE DIRECCIONAMIENTO PUEDE CIFRAR UNA CLAVE DE CIFRADO DE TRANSFERENCIA CON UNA SEGUNDA CLAVE DE CIFRADO DERIVADA DE LA DECLARACIÓN DE AFIRMACIÓN. LA CABEZA DE PROTOCOLO DE DIRECCIONAMIENTO PUEDE RECUPERAR LOS DATOS PROTEGIDOS, Y CIFRAR LOS DATOS PROTEGIDOS CON LA CLAVE DE CIFRADO DE TRANSFERENCIA Y UNA ETIQUETA DE AUTENTICACIÓN, QUE UNE EL SOLICITANTE CON EL ID DE TRUSTLET. LA CABEZA DE PROTOCOLO DE DIRECCIONAMIENTO PUEDE PROPORCIONAR LA CLAVE DE CIFRADO DE TRANSFERENCIA CIFRADA, LOS DATOS PROTEGIDOS CIFRADOS, Y LA ETIQUETA DE AUTENTICACIÓN CIFRADA AL SOLICITANTE.
