Abstract

El objetivo de la presente invención es limitar el impacto de las violaciones de seguridad que son los emuladores del módulo de seguridad. Este objetivo se alcanza mediante una unidad procesadora de dataos de acceso condicional digitales de audio / video, encriptados mediante palabras de control, responsable de procesar los mensajes de seguridad que contienen por lo menos un criptograma relacionado con una palabra de control y una instrucción relacionada con la palabra de control, caracterizado porque incluye medios para recibir por lo menos dos microprogramas mediante mensajes de seguridad, ejecutables por el módulo de seguridad; comprendiendo el módulo de seguridad medios para almacenar por lo menos dos microprogramas y medios para recibir una instrucción contenida en el mensaje de seguridad, para seleccionar el microprograma indicado por la instrucción, para ejecutar el microprograma con al menos el criptograma como parámetro de ejecución; permitiendo esta ejecución que el cálculo de la palabra de control sea enviado de nuevo a la unidad procesadora de audio / video.
