SYSTÈME ET PROCÉDÉ DE DISTRIBUTION DE VALEUR RÉCUPÉRABLE D'INFORMATIONS SECRÈTES

摘要

A method-performed by a computer is provided by which secret reconstructible value distribution system is provided. The method includes generating n secret reconstructible values based on an original secret used to process predetermined information, wherein the original secret can be reconstructed using at least k secret reconstructible values among the generated n secret reconstructible values and n>=k>=2 is established, storing the generated n secret reconstructible values in the corresponding n physical storage devices, and deleting the generated original secret.
