Title
(EN) STORAGE OF CRYPTOGRAPHIC KEY ON A DIGITAL PAYMENT DEVICE (DPD)
(FR) STOCKAGE DE CLÉ CRYPTOGRAPHIQUE SUR UN DISPOSITIF DE PAIEMENT NUMÉRIQUE (DPD)
Abstract
(EN)
A Digital Payment Device (DPD) including a Digital Transaction Processing Unit (DTPU), wherein the DPD includes a first cryptographic key stored in a secure storage area of the DPD, wherein the first cryptographic key matches a second cryptographic key stored on the DTPU, the second cryptographic key being associated with a security domain of the DTPU, wherein the first cryptographic key enables encryption for a digital object, such that the digital object is authenticatable against the second cryptographic key.
(FR)
L’invention concerne un dispositif de paiement numérique (DPD) qui comprend une unité de traitement de transaction numérique (DTPU), le DPD comprenant une première clé cryptographique stockée dans une zone de stockage sécurisée du DPD, la première clé cryptographique correspondant à une seconde clé cryptographique stockée sur la DTPU, la seconde clé cryptographique étant associée à un domaine de sécurité de la DTPU, la première clé cryptographique permettant un chiffrement pour un objet numérique, de telle sorte que l'objet numérique peut être authentifié par rapport à la seconde clé cryptographique.
