Abstract
(EN) In one embodiment, a method for securely distributing secret keys for hardware devices is disclosed. A distributor server transmits to a provider server an order for hardware devices. Each hardware device has a unique identifier and at least one secret key for authentication. The provider server sends a database associated with the distributor, for each of the hardware devices, the unique identifier and an unencrypted version of the at least one secret key. In response to an order received by the distributor from a customer for a portion of the hardware devices, the distributor server provides the database the unique identifiers and an associated customer order identifier, and the distributor server provides a customer server the unique identifiers. In response to the customer logging into the database and providing the order information, the database provides the customer the unencrypted keys for the hardware devices to allow authentication.
(FR) Dans un mode de réalisation, l'invention concerne un procédé de distribution sécurisée de clés secrètes pour des dispositifs matériels. Un serveur de distribution transmet à un serveur de fournisseur une commande de dispositifs matériels. Chaque dispositif matériel possède un identifiant unique et au moins une clé secrète pour l'authentification. Le serveur de fournisseur envoie une base de données associée au distributeur, pour chacun des dispositifs matériels, l'identifiant unique et une version non chiffrée de ladite clé secrète. En réponse à une commande d'un client, reçue par le distributeur, pour une partie des dispositifs matériels, le serveur de distribution fournit à la base de données les identifiants uniques et un identifiant de commande de client associé, et le serveur de distributeur fournit à un serveur de client les identifiants uniques. En réponse au fait que le client se connecte à la base de données et fournit les informations de commande, la base de données fournit au client les clés non chiffrées pour les dispositifs matériels afin de permettre l'authentification.
