Abstract

Au moins une clé de déchiffrement périmée (Sn) pour déchiffrer des données chiffrées asymétriquement est recouvrée dans un terminal (T) après une génération d'un couple cryptographique clé de chiffrement/clé de déchiffrement mémorisé dans un support cryptographique, tel qu'une carte à puce (CP). La clé de déchiffrement périmée est mémorisée dans une base de données (BL) accessible à un usager du terminal, ladite clé étant préalablement chiffrée en fonction de la nouvelle clé de chiffrement générée. Dans le terminal relié au support cryptographique, la clé de chiffrement périmée chiffrée est déchiffrée en fonction de la clé de déchiffrement mémorisée dans le support cryptographique afin de déchiffrer les données chiffrées en fonction de la clé de déchiffrement périmée ainsi déchiffrée.
