(FR) PROCEDE SECURISE DE PARTAGE RETARDE DE DONNEES ENTRE UN UTILISATEUR EMETTEUR ET PLUSIEURS UTILISATEURS DESTINATAIRES, AVEC CREATION LOCALE D'UN CONTENEUR.
Abstract
(FR) Procédé de partage de fichiers (2) entre un utilisateur (A) émetteur et plusieurs utilisateurs (Bk) destinataires, qui comprend trois phases : - Ecriture : ○ Créer au niveau de l'utilisateur (A) émetteur un conteneur (6) de fichiers, associé aux utilisateurs (Bk) destinataires ; ○ Pendant un délai (T1) d'écriture, permettre à l'utilisateur (A) émetteur l'accès en écriture au conteneur (6) ; - Archivage : ○ Transmettre le conteneur (6) à un système (1) informatique distant ; ○ Copier le conteneur pour chaque utilisateur (Bk) destinataire et crypter chaque copie à l'aide de la clé (ZBk) publique du destinataire ; ○ Pendant un délai (T2) d'archivage, stocker chaque conteneur (6Bk) crypté ; - Partage : permettre à chaque utilisateur (Bk) destinataire de télécharger le conteneur (6Bk) crypté en vue de le décrypter à l'aide de sa clé (BkZ) privée.
