Abstract

SE DESCRIBEN UNOS METODOS Y APARATOS PARA ASEGURAR QUE PROGRAMAS QUE COMPRENDEN AL MENOS UNA DE ENTRE SEÑALES DE DATOS, DE AUDIO Y DE VIDEO, QUE SON SOLICITADOS POR UN CLIENTE DE UN SUMINISTRADOR DE SERVICIOS (SP) (110), VIA UN SISTEMA (10) DE SERVICIOS DE INFORMACION INTERACTIVOS, QUE TRANSMITE LOS PROGRAMAS SOLICITADOS EN PAQUETES PORTADORES DEL PROGRAMA A UNA UNIDAD DE CAJA ADOSADA AL APARATO DE TELEVISION (STU) (90) ASOCIADO CON UN CLIENTE (130), Y QUE SON ACCESIBLES SOLAMENTE PARA CLIENTES AUTORIZADOS (130). EL APARATO ESTA SITUADO ENTRE EL SP (110) Y LA STU (90) Y COMPRENDE: UN MEDIO PARA RECIBIR LOS PAQUETES PORTADORES DEL PROGRAMA EN UN PRIMER PROTOCOLO DE RED DESDE UN PRIMER ENLACE DE DATOS (40) Y LA RETIRADA DE LOS PAQUETES DEL PRIMER PROTOCOLO DE RED; UN MEDIO PARA AÑADIR ACCESO CONDICIONAL A LOS PAQUETES PORTADORES DEL PROGRAMA; Y UN MEDIO PARA REENCAPSULAR LOS PAQUETES PORTADORES DEL PROGRAMA EN UN SEGUNDO PROTOCOLO DE RED Y EMITIR LOS PAQUETES PORTADORES DEL PROGRAMA POR UN SEGUNDO ENLACE DE DATOS (50). SE DESCRIBEN UNOS METODOS Y APARATOS PARA APLICAR UN ACCESO CONDICIONAL QUE COMPRENDEN PAQUETES PORTADORES DEL PROGRAMA SELECCIONADO CIFRADO CON UNA PRIMERA CLAVE; EL CIFRADO DE LA PRIMERA CLAVE, CON UNA SEGUNDA CLAVE; Y, EL CIFRADO DE LA SEGUNDA CLAVE SEGUN UN ALGORITMO DE CIFRADO DE CLAVE PUBLICA USANDO UNA CLAVE PUBLICA CORRESPONDIENTE A UNA CLAVE PUBLICA ALMACENADA DENTRO DE LA STU (90) ASOCIADA CON EL CLIENTE (130).
