    摘要： Various embodiments facilitate secure content sharing between a plurality of receiving devices, such as set-top boxes. One embodiment is a system with a distribution server communicatively coupled via a satellite communication system to a plurality of set-top boxes that are located at different customer premises. The distribution server is operable to provide access control information via the satellite communication system to a first set-top box and a second set-top box of the plurality, with the access control information enabling the first set-top box to securely share content of the first set-top box with the second set-top box. This abstract is provided to comply with rules requiring an abstract, and it is submitted with the intention that it will not be used to interpret or limit the scope or meaning of the claims.

    摘要： Provided is a content distribution method which allows a source device to safely distribute copyrighted content to a sink device in response to a request from the sink device as a trigger. The content distribution method includes a list transmission step S11, a content request step S12, and a content transfer step S13. In S11, a source device transmits metadata which includes a format identifier indicating that content is distributable under the specification of the HDCP and the URL of the content. In S12, a sink device makes a request for content identified by the URL after adding information necessary for authentication processing to the request. In S13, the source device creates an encryption key by performing the authentication processing on the sink device in accordance with the information necessary for the authentication processing, encrypts the content using the encryption key, and transfers the encrypted content to the sink device.

    摘要： In an approach, a target computing device receives a pairing request from a controller computing device, the pairing request including controller credentials that were previously received by the controller computing device from an authentication server computer and encrypted under a service key. The target computing device forwards the pairing request to the authentication server, the authentication server computer being configured to return a pairing response based at least in part on the controller credentials. The target computing device receives the pairing which includes a shared secret encrypted under a target device key and the same shared secret encrypted under a controller key. The target computing device decrypts the shared secret encrypted under the target device key and forwards the shared secret encrypted under the controller key to the controller device. Using the decrypted shared secret, the target computing device establishes a secure connection to the controller computing device.
