Title (EN) SECURE MEMORY CARD WITH LIFE CYCLE PHASES
(FR) CARTE MEMOIRE SECURISEE A PHASES DE CYCLE DE VIE
Abstract: front page image
(EN)A secure memory card with encryption capabilities comprises various life cycle states that allow for testing of the hardware and software of the card in certain of the states. The testing mechanisms are disabled in certain other of the states thus closing potential back doors to secure data and cryptographic keys. Controlled availability and generation of the keys required for encryption and decryption of data is such that even if back doors are accessed that previously encrypted data is impossible to decrypt and thus worthless even if a back door is found and maliciously pried open.
(FR)L'invention concerne une carte mémoire sécurisée à capacité de chiffrement comprenant divers états de cycle de vie permettant l'essai du matériel et du logiciel de la carte dans certains de ses états. Les mécanismes d'essai sont désactivés dans certains autres états, fermant ainsi les portes dérobées éventuelles afin de sécuriser les données et les clés cryptographiques. La disponibilité et la génération commandée des clés nécessaires au chiffrement et au déchiffrement des données font que, même si les portes dérobées sont accessibles, les données préalablement chiffrées sont impossibles à déchiffrer et donc sans valeur, y compris si une porte dérobée est trouvée et ouverte par malveillance.
