2. Device Definitions 2.1. Device Type The following device type identifies a device that is compliant with this template: urn:schemas-upnp-org:device:RemoteUIServerDevice:1 2.2. Device Model It is recommended that RemoteUIServerDevice be implemented with support for securing UPnP™ actions. It is also recommended that securing of UPnP™ action is done using the DeviceSecurity service as defined by the UPnP™ security working committee. If implemented, the DeviceSecurity service must be contained either inside RemoteUIServerDevice implementation or in a device that encompasses the RemoteUIServerDevice. These two models are described below. 2.2.1. Description of Device Requirements The following table briefly describes the service used in RemoteUIServerDevice.
2.2.1.1. DeviceSecurity within RemoteUIServerDevice This model is typically applicable to physical devices that need DeviceSecurity functionality (including device ownership and access control) to be used only by the RemoteUIServerDevice. In this case, products that expose devices of the type urn:schemas-upnp-org:device:RemoteUIServerDevice:1 must implement minimum version numbers of the required service specified in the table below.
2.2.1.2. DeviceSecurity outside RemoteUIServerDevice This model is typically applicable to physical devices that implement Remote UI server functionality, but the RemoteUIServerDevice may use DeviceSecurity that is already part of another device. An example of this would be where urn:schemas-upnp-org:device: RemoteUIServerDevice:1 is implemented inside a device of the type urn:schemas-upnp-org:device: BasicDevice:1. The BasicDevice in this case contains the DeviceSecurity service that may be used by another UPnP™ device e.g., MediaRenderer. The implementation of RemoteUIServerDevice must contain the minimum version number of the service specified in the table below.
Relationships between Services Figure 2 shows the logical structure of the device and services defined by the working group for UPnP™ technology enabled Remote UI servers that may use the DeviceSecurity service for other UPnP™ devices contained in the same physical device. RemoteUIServer service may be dependent on the DeviceSecurity service for providing access control to the actions defined in the services.
