Abstract

La presente invención se refiere a un sistema, a un dispositivo y a un método para redistribuir de forma segura contenido de acceso condicional dentro de una red de hospitalidad. El contenido se recibe en un servidor de puerta de interconexión de redes en la red de hospitalidad, se descifra y re-codifica por el servidor de puerta de interconexión de redes y se re-distribuye en formato recodificado a uno o más dispositivos de cliente dentro de la red de hospitalidad. Los dispositivos de cliente son capaces de decodificar el contenido re-codificado, sin utilizar ningún equipo especial de acceso condicional, gracias a un secreto compartido, un algoritmo compartido y un valor públicamente accesible dentro del contenido redistribuido.
