Title (EN) Secure Programming of Secret data
(FR) PROGRAMMATION SÉCURISÉE DE DONNÉES SECRÈTES
Abstract:
(EN) Secure Programming of Secret data A method is provided. The method comprises providing a device comprising a secure element coupled to a non-volatile memory, the non-volatile memory comprising a first cryptographic key stored therein; the secure element decrypting and authenticating first secret data using the first cryptographic key to form second secret data; and then rendering the true value of the first cryptographic key unreadable.
(FR) L'invention concerne un procédé de programmation sécurisée de données secrètes. Le procédé consiste à fournir un dispositif comprenant un élément sécurisé couplé à une mémoire non-volatile contenant une première clé de chiffrement. L'élément sécurisé déchiffre et authentifie des premières données secrètes au moyen de la première clé cryptographique, pour former des secondes données secrètes, et rend ensuite la vraie valeur de la première clé cryptographique illisible.
