| Sistema de autenticación y de gestión de las claves de criptación para los servicios audiovisuales |
 |
Esta Recomendación describe tres métodos de gestión de claves de criptación:- ISO 8732;- Diffie-Hellman; y- RSA.Los métodos se aplican a la criptación de señales audiovisuales transmitidas digitalmente con la estructura de trama H.221. Los mensajes de gestión descritos se transmiten por el canal de señal de control H.221, cuya estructura y utilización se definen en la Rec. UIT-T H.233.Esta revisión de la Recomendación mejora la redacción del texto, suprime las ambigüedades de algunos aspectos relativos al intercambio de claves de longitud asimétrica y suprime las referencias a la criptación MLP de las Recomendaciones de la serie T.120, ya que el tema queda en estudio. Además, se han actualizado las referencias a ASN.1 de acuerdo con la versión más reciente de su especificación. |
