Abstract
A method by a management node for managing a device operable to join a network includes receiving from the device a request to join the network, the request including a device specific parameter and a token, and generating an authentication parameter from the device specific parameters and the token. The method further includes authorising the device to join the network if the authentication parameter fulfils a validity criterion. Generating an authentication parameter from the device specific parameters and the token includes generating an input including the device specific parameters and the token, computing a cryptographic function of the generated input, and setting an output of the cryptographic function as the authentication parameter. Also disclosed are a method for operating a device, a management node, a device and a computer program.
