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.

Abstract: A computing device is disclosed that comprises processing circuitry configured to cause the computing device to expose (110), to an application server, at least one resource hosted by the computing device, and to provide (120), to the application server, a hypermedia document that provides access to a value of a parameter characterising access of the computing device to a communication network over which the computing device is operable to communicate. The hypermedia document conforms to a data model for use by constrained devices. Also disclosed is an application server that is operable to use the value of the parameter provided in the hypermedia document to prepare an interaction with the resource hosted by the computing device. Methods performed by a computing device and application server are also disclosed.

Abstract: Nodes and methods for controlling access to resources of data objects exposed by at least one computing device is disclosed. The data objects conform to an object model that specifies, for a given object name of a data object, one or more resources which may be associated with instances of a data object of that object name. An access control node is configured to receive a request to access a resource of a data object instance (110), determine a compatibility of the request with an access rule (120) and perform at least one of allowing or denying the request in accordance with the determined compatibility (130). The request to access a resource of the data object instance identifies the resource at an identification abstraction level that specifies how the resource may be accessed, and the access rule specifies one or more limitations on access to resources at a semantic abstraction level that indicates a semantic content of a data object or resource.

Abstract: According to a first aspect there is provided a method of enabling an Internet device that is only awake periodically to receive communications sent when the device is not awake. The method comprises, at the device, during an initial awake period, establishing a connection to a peer of a RELOAD overlay network as a RELOAD client, and creating a dictionary resource at the RELOAD peer using the Node-ID of the device as the Resource-ID. Then, during a further awake period, establishing a connection to the RELOAD peer and obtaining any communications sent to the device during a sleeping period of the device by retrieving data from the dictionary resource stored at the RELOAD peer.
