摘要： Methods and arrangements for enabling the use of a first device (300) for controlling transfer of media content from a content provider (306) to a second device (302). The first device has a pre-established security association with the communications network. When the network detects a request made by the first device for delivery of media content to the second device, key information is established which enables determination of one or more media keys for encryption of the media content. The network sends key information to the content provider and to the first device. The content provider then delivers media content encrypted by the media key(s) to the second device. Further, the first device forward the media key(s) over a local communication link to the second device for decryption of media content encrypted by the media key(s) when delivered by the content provider.

摘要： Disclosed is a DRM device and method for providing secure linking to a user identity. A first request is sent to a subscriber identity module. A message is received from the subscriber identity module via a secure authenticated channel. The message comprises at least a master key identifier, a random number, and a derived key. In response to the message, a second request is sent to a DRM server. The second request comprises at least a master key identifier, the device identifier, and a random number. Also disclosed is a DRM server and method for providing secure linking to a user identity. A first request is received from a DRM device. The first request comprises at least master key identifier, a device identifier, and a random number. The DRM device is authenticated. A second request for an application specific key is sent to a trusted key management server. The second request comprises at least a master key identifier. At least a key is received from the trusted key management server. A derived key is determined from the key received from the trusted key management server based at least on the device identifier and the random number. A challenge/response scheme is used to determine whether the derived key of the DRM server matches a derived key of the DRM device.
