摘要： Methods, systems, and products are disclosed for delivering broadcast encryption content. Embodiments of the present invention typically include receiving in a cluster broadcast encryption content; receiving in a cluster a rights object defining device-oriented digital rights for broadcast encryption content; and administering the broadcast encryption content on one or more network devices in the cluster in dependence upon the digital rights. In some embodiments, administering the broadcast encryption content on one or more network devices in the cluster in dependence upon the digital rights include mapping the device-oriented digital rights to digital rights supported in the cluster, excluding device-oriented rights not supported in the cluster. In some embodiments, mapping the device-oriented digital rights to digital rights supported in the cluster includes supporting in the cluster only those device-oriented digital rights having direct analogs in the cluster.

摘要： A method for verifying control accesses between a device on a non-proprietary bus and a device on a proprietary bus is disclosed. A gateway controller is connected between a proprietary bus and a non-proprietary bus. A determination is made as to whether or not a non-proprietary device is registered to more than one gateway controller. In response to a determination that the non-proprietary device is registered to more than one gateway controller, another determination is made as to whether or not the non-proprietary device is a portable device. In response to a determination that the non-proprietary device is a portable device, another determination is made as to whether or not a number of acceptable duplication has been exceeded. In response to a determination that the number of acceptable duplication has been exceeded, a flag is set to indicate a control access violation has occurred.

摘要： A system, method and computer program for enforcing network cluster proximity requirements using a proxy is useful in preventing unauthorized devices from receiving encrypted broadcast content intended for only authorized users within a network cluster. The current art allows users to remotely establish trust via a cryptographic handshake. This results in encrypted broadcast content being delivered to unauthorized devices. The present invention assures that encrypted broadcast content is delivered to only authorized devices, allowing authorized remote devices to receive encrypted broadcast content while preventing unauthorized remote devices from doing so. The present invention enforces network proximity requirements to authorized devices within a defined area by timing the cryptographic handshaking, and by authorizing device proxies within a geographic area for retransmitting to authorized remote devices outside said geographic area.

摘要： Systems, methods and media for encrypting and decrypting content files are disclosed. More particularly, hardware and/or software for adding an additional level of indirection to a title key encryption scheme are disclosed. Embodiments may include generating by a cryptographic system a binding key based on binding information. Embodiments may also include encrypting by the cryptographic system a secret key with the binding key and generating a title key associated with at least one content file. Embodiments may also include encrypting by the cryptographic system the title key with the secret key and the at least one content file with the title key. Further embodiments may include receiving an indication that the binding information has changed, generating a new binding key based on the new changed binding information, and re-encrypting the secret key with the new binding key.
