Abstract

Procédé de certification de partage d’un fichier, procédé de confirmation de partage d’un fichier et dispositifs correspondants Un procédé de certification par un premier dispositif (A) d’un partage d’un fichier (file) à au moins un deuxième dispositif (B), est mis en œuvre par ledit premier dispositif (A) et comprend : - une réception (E2), en provenance dudit deuxième dispositif (B), d’un accusé de réception (ack_file) par le deuxième dispositif du fichier chiffré (c_file), - un stockage (E3), dans un espace de stockage numérique (BDD1), d’une première donnée (d1) chiffrée et déchiffrable par le deuxième dispositif, et dudit accusé de réception (ack_file) du fichier chiffré (c_file), - une réception (E6), en provenance dudit deuxième dispositif, d’une deuxième donnée (d2), - une vérification (E7) si la deuxième donnée (d2) est égale à la première donnée (d1), et, en cas de vérification positive, déclenchement (E8) d’une transmission à destination du deuxième dispositif (B) d’une clef de déchiffrement (k_file) du fichier chiffré (c_file).
