Abstract

L'invention concerne un procédé de chiffrage de contenu, ledit procédé consiste à chiffrer une première pluralité de blocs de contenu séparés afin d'obtenir une deuxième pluralité de blocs de contenu chiffré une fois ; à échanger au moins une partie du contenu stocké dans un premier ensemble de blocs de la deuxième pluralité de blocs de contenu chiffré une fois avec au moins une partie du contenu stocké dans un deuxième ensemble de blocs de la deuxième pluralité de blocs du contenu chiffré une fois afin de générer une troisième pluralité de blocs du contenu chiffré une fois ; et à chiffrer la troisième pluralité de blocs de contenu chiffré afin de générer une quatrième pluralité de blocs de contenu chiffré deux fois.
