Abstract

The embodiments of the present invention relate to apparatuses in the form of a first network unit and a device, and also relates to a method for enabling protection of a bootstrap message in a device management network system. The method comprises: receiving at the first network unit, a request to bootstrap the device; transmit a request for a bootstrap key, to a second network unit; receiving a message comprising the bootstrap key and further comprises trigger information and transmitting the trigger information to the device to trigger generation of the bootstrap key internally in the device. Thereafter a protected bootstrap message can be transmitted to the device from the first network unit, and when the device verifies and/or decrypts the bootstrap message, device management (DM) sessions can start between the device and the first network unit.

Claims20

Dependent claims

A node implementing a network application function for enabling protection of a bootstrap message, the node comprising:

one or more processing circuits and a memory, the memory containing instructions executable by the one or more processing circuits whereby the network application function is configured to:
receive an identifier of a device that is to be bootstrapped and an identifier of a subscriber associated with said device;
send to a boostrapping server function a request for a bootstrap key that is associated with the identifier for said subscriber and that will protect a bootstrap message to be sent to the device to provision the device with the ability to initiate a management session with a device management (DM) network system over an IP connection, wherein said management session configures the device with settings that the device requires in order for the device to support one or more services, wherein the request for the bootstrap key also requests trigger information that will trigger the device itself to generate the bootstrap key;
receive the requested bootstrap key and the trigger information from the bootstrapping server function;
and
send the trigger information towards the device for bootstrapping the device.
