1. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, direct the apparatus at least to: execute a configuration protocol between the apparatus and a first device to generate a first key to be shared between the apparatus and the first device; enable the first device, in an instance in which the first device is a control point for a privileged service from a second device, to advertise that it is able to control the privileged service; derive a second key by executing a key derivation function; derive, from the first key, a third key, by executing a key derivation procedure between the apparatus and the second device, for the privileged service in an instance in which the apparatus determines that the first device should be configured to control the privileged service; encrypt the third key using at least the second key; and send the encrypted third key to the first device, wherein the third key is used to encrypt data transferred between the first device and the second device.
