SECURELY TRANSFERRING THE AUTHORIZATION OF CONNECTED OBJECTS

For securely transferring an authorization of connected objects, a supervision server (SS): receives a report (Rp) on authentication, authorization and accounting of a connected object (CO), said report containing the IP address at which the connected object can be reached a persistent identifier of the connected object, determines a manufacturer of the connected object by means of said persistent identifier, identifies at least one pre-established trust domain associated with said manufacturer, by means of a secure policy associated with said manufacturer, the trust domain defining a set of credentials or certificates and mechanisms for communication between the supervision server (SS) and an application server (AS), producing an authorization state of the connected object by means of the received report (Rp), instructs a network device (ND) to be programmed with rules that are identified in the secure policy associated with the manufacturer and that admit the IP address of the connected object, the network device (ND) allowing access to the application server (AS), transmits a message to the application server (AS) via the identified trust domain, the message containing the authorization state of the connected object.
