| Gestion des clés de chiffrement et système d'authentification pour les services audiovisuels |
 |
La présente Recommandation spécifie trois méthodes de gestion des clés de chiffrement:- les méthodes ISO 8732;- Diffie-Hellman;- RSA.Elles s'appliquent au chiffrement des signaux audiovisuels transmis numériquement dans la structure de trame H.221. Les messages de gestion définis dans ce texte sont transmis dans le canal du signal de commande de chiffrement (ECS, encryption control signal) H.221 dont la structure et l'utilisation sont spécifiés dans la Rec. UIT-T H.233.La révision de la Recommandation améliore la lisibilité générale du texte, lève des ambiguïtés de certains aspects touchant à l'échange de clés de longueur asymétrique et supprime les références au cryptage conformément aux Recommandations de la série T.120, sujet qui nécessite un complément d'étude. Les références à la notation ASN.1 ont été mises à jour conformément à la version la plus récente de sa spécification. |
