Title
(EN) BOOTSTRAPPING WITH COMMON CREDENTIAL DATA
(FR) AMORÇAGE AVEC DONNÉES COMMUNES DE JUSTIFICATIFS
Abstract
(EN)
According to the present techniques there is provided a computer implemented method of bootstrapping a device by a bootstrap server, the method comprising: receiving, at the bootstrap server from the device as part of a bootstrap process, common credential data including a trust indicator to indicate that the common credential data is common for a group of devices;obtaining, at the bootstrap server, resource credential data based on or in response to the common credential data, the resource credential data to enable the device to authenticate with a resource; transmitting, from the bootstrap server to the device, the resource credential data.
(FR)
La présente invention concerne un procédé, mis en œuvre par ordinateur, d'amorçage d'un dispositif par un serveur d'amorçage, le procédé comportant les étapes consistant à: recevoir au niveau du serveur d'amorçage, en provenance du dispositif, dans le cadre d'un processus d'amorçage, des données communes de justificatifs incluant un indicateur de confiance servant à indiquer que les données communes de justificatifs sont communes à un groupe de dispositifs; obtenir au niveau du serveur d'amorçage, des données de justificatifs de ressources d'après les données communes de justificatifs ou en réaction à ces dernières, les données de justificatifs de ressources servant à permettre au dispositif de s'authentifier auprès d'une ressource; transmettre, du serveur d'amorçage au dispositif, les données de justificatifs de ressources.
