Abstract

Método para controlar la integridad y la autenticidad de un conjunto de datos recibidos (M1 a Mn) en una unidad de decodificación de televisión de pago compuesta por un descodificador (IRD) y una unidad de seguridad (SC) así como por medios de comunicación (NET, REC) con un centro de gestión, comprendiendo las etapas siguientes:- calcular una información de control (Hx) representativa del resultado de una función dada unidireccional y libre de colisiones, aplicada a todos o parte de los datos (M1 a Mn),- encriptar la información de control (Hx) mediante una primera clave (k1) dada por la unidad de seguridad- establecer la conformidad de la información de control (Hx) por parte de los datos de gestión (R) provenientes del centro de gestión mediante uno de los medios de comunicación.<EMI FILE="00056183_1" ID="1" IMF=JPEG >
