Title (EN) APPLICATION CERTIFICATE
(FR) CERTIFICAT D'APPLICATION
Abstract:
(EN) A method for a device comprises enrolling a specified application installed on the device into a chain of trust provided by a private key infrastructure. In the chain of trust, a child certificate is attested as valid by an attestor associated with a parent certificate in the chain of trust. Enrolling includes generating an application certificate 20-A for verifying that the specified application is installed on the device 2. The application certificate is a descendant certificate of the device certificate associated with the device and the chain of trust.
(FR) La présente invention concerne un procédé pour un dispositif, consistant à intégrer une application spécifiée installée sur le dispositif dans une chaîne de confiance fournie par une infrastructure de clé privée. Dans la chaîne de confiance, la validité du certificat enfant est attestée par un certificateur associé à un certificat parent dans la chaîne de confiance. L'intégration consiste à générer un certificat d'application (20-A) permettant de vérifier que l'application spécifiée est installée sur le dispositif (2). Le certificat d'application est un certificat descendant du certificat de dispositif associé au dispositif et à la chaîne de confiance.
