Title (EN) DEVICES AND METHODS FOR KEY ATTESTATION WITH MULTIPLE DEVICE CERTIFICATES
(FR) DISPOSITIFS ET PROCÉDÉS D'ATTESTATION DE CLÉ AVEC MULTIPLES CERTIFICATS DE DISPOSITIF
Abstract:
(EN) According to an aspect, a device with key attestation features is provided. The device comprises an operating system stored in its memory, the operating system comprising a secure environment including a trusted application, and two or more device certificates, each associated with a device key pair, stored in the memory of the device. The trusted application is configured to handle key pair generation requests and key pair attestation requests to read an indication of a preferred device certificate. An attestation certificate that is generated in response to the key pair attestation request is then signed using one of the two or more device certificates with its associated device key pair based on the indication of a preferred device certificate.
(FR) Un aspect de l'invention concerne un dispositif avec des caractéristiques d'attestation de clé. Le dispositif comprend un système d'exploitation stocké dans sa mémoire, ledit système d'exploitation comprenant : un environnement sécurisé comprenant une application de confiance ; et au moins deux certificats de dispositif, chacun étant associé à une paire de clés de dispositif, stockés dans la mémoire du dispositif. L'application de confiance est configurée pour gérer des demandes de génération de paire de clés et des demandes d'attestation de paire de clés afin en vue de lire une indication d'un certificat de dispositif préféré. Un certificat d'attestation qui est généré en réponse à la demande d'attestation de paire de clés est ensuite signé en utilisant l'un des au moins deux certificats de dispositif avec sa paire de clés de dispositif associée d’après l'indication d'un certificat de dispositif préféré.
