摘要： Provided are techniques for the creation and storage of an archive for binding IDs corresponding to a cluster of devices that render content protected by a broadcast encryption scheme. When two or more clusters are merged, a binding ID corresponding to one of the clusters is selected and a new management key is generated. Binding IDs associated with the clusters other than the cluster associated with the selected binding ID are encrypted using the new management key and stored on a cluster-authorized device in a binding ID archive. Content stored in conformity with an outdated binding ID is retrieved by decrypting the binding ID archive with the management key, recalculating an old management key and decrypting the stored content.

摘要： A message comprising an indication of a management key block and an indication of an authorization table is received at a first network device from a second network device. The indication of the management key block, the indication of the authorization table, and a response message generated based on validating the indication of the management key block and the indication of the authorization table are stored. A second message comprising a second indication of the management key block and a second indication of the authorization table is received at the first network device from the second network device. The first network device communicates with the second network device in accordance with the stored response associated with the first message on determining that the second indication management key block and the second indication of the authorization table match corresponding stored indications of the management key block and the authorization table.

摘要： A first message comprising a received indication of a management key block (MKB) and a received indication of an authorization table (AT) is received at a first network device from a second network device. The received indications of the MKB and AT are validated by comparing them to generated indications of the MKB and AT, respectively. A response is generated based on the validation of the received indications and transmitted from the first network device to the second network device. The generated indications and response are stored. A second message comprising a second received indication of the MKB and a second received indication of the AT is received at the first network device from the second network device. The first network device communicates with the second network device in accordance with the stored response on determining that the second received indications match corresponding stored indications.

摘要： Provided are techniques to enable a device that provides a service to authorize a second device for receiving the service and the delivery of the service to the second device and other devices within a trusted network. A signed Management Key Block (MKB) is generated and transmitted over a network. Devices authorized to access a particular service parse the MKB and transmit a request. A server associated with the service determines whether or not the device is authorized to access the service based upon data included in the request. The first device may issue a challenge to the second device for authentication purposes. If service is approved, service is initiated, either from the first device or another authorized device. Devices may be organized into classes such that devices of a specific class are authorized to access the service.

摘要： Provided are techniques to enable, using broadcast encryption, a device to locate a service offered by a server with the knowledge that the service offered by the server is a trusted service. A signed enhanced Management Key Block (eMKB) includes a trusted service locator (TSL) that includes one or more records, or “trusted service data records” (TSDRs), each identifying a particular service and a corresponding location of the service is generated and transmitted over a network. Devices authorized to access a particular service parse the eMKB for the end point of the service, connect to the appropriate server and transmit a request.
