Abstract

Sistema que provee una unidad criptográfica que genera claves secretas a las que no puede acceder directamente el software ejecutado por un controlador. La unidad criptográfica puede incluir un dispositivo restrictor, una máquina de estados finitos, un generador de numeros aleatorios conectado en comunicacion y una memoria. La memoria almacena valores generados por el generador de numeros aleatorios. El dispositivo restrictor y la máquina de estados finitos incluyen logica de hardware que restringe el acceso o los cambios en el contenido de la memoria.
