摘要: L'invention concerne un procede de chiffrement d'une trame ou super DVB-S2 comportant au moins premier type modulee avec une premiere modulation M 1 et deuxieme 2 , caracterise en ce qu'il comporte les etapes suivantes : The invention relates to a method of encrypting frame or superframe comprising at least first modulated with and second 2, characterized in that it comprises the steps of: • inserer sein la DVB-S2, nombre dummy trames « n » structure longueur afin d'obtenir ST meme duree T definie, pour plusieurs configurations donnees, taille est definie dans le champ 29 du mot code PLS etant composee d'un PLHeader n-1 slots 90 symboles complexes, inserting number frames "n" length obtain same duration defined, for multiple data patterns, size is defined field ​​29 word frame, composed complex symbols, appliquer algorithme sur ainsi obtenue. apply an encryption algorithm on obtained.
