Abstract: L'invention concerne un procédé et un appareil permettant de gérer des composants d'un code secret suivant un système de partage de secret. Ledit système divise une valeur de secret, R, en n composant de secret (R1, R2,..., Rn) et un super composant, S, de manière que R puisse être calculé à partir (i) de n'importe quel k ou de plusieurs Ri composants (k <n); ou (ii) de S et de n'importe quel composant de Ri. Les composants de secret (R1, R2,..., Rn) sont distribués à un certain nombre d'utilisateurs autorisés. Un système de partage de secret multi-seuils affecte divers utilisateurs d'un groupe à un certain nombre de classes. Chaque classe d'utilisateurs a un niveau de seuil correspondant qui indique le nombre d'utilisateurs devant se regrouper avec les composants qui leur sont affectés pour obtenir l'accès au secret partagé. Le système de partage de secret multi-seuils divise le secret en n composants, chacun ayant un niveau de seuil qui lui est affecté ( soit, le nombre des composants qui sont nécessaires pour obtenir le secret). Tout composant ayant un niveau de seuil inférieur peut répondre au rôle d'un composant ayant un niveau de seuil plus élevé. Le système multi-seuils produit un système hiérarchisé qui permet à différents groupes de personnes ayant des seuils différents de partager le secret, R.
