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： Provided is a method for the standardization of information management among different information sources and different information formats. With respect to information sources that employ different information storage formats, an organizational proxy, or “shadow,” of the organization structure of the first information source is created in the second information source and a shadow of the second information source is created in the first information source. Information stored in conjunction with the first information source is copied into the shadow within the second information source. The information in the first source is then either maintained or a link to corresponding information in the second information source is created within the first information source and the first information is deleted. The claimed subject matter provides a graphical user interface (GUI) so that a user can copy information from one information source to another by executing a “drag & drop” action.
摘要翻译：提供了不同信息源和不同信息格式之间信息管理标准化的方法。对于采用不同信息存储格式的信息源，在第二信息源中创建第一信息源的组织结构的组织代理或“影子”，并且在第一信息源中创建第二信息源的阴影信息来源。与第一信息源一起存储的信息被复制到第二信息源内的阴影中。然后维护第一源中的信息，或者在第一信息源内创建到第二信息源中的相应信息的链接，并且删除第一信息。所要求保护的主题提供图形用户界面（GUI），使得用户可以通过执行“拖放”动作将信息从一个信息源复制到另一个信息源。

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： Methods, systems, and products are disclosed for controlling with rights objects delivery of broadcast encryption content for a network cluster from a content server outside the cluster that include receiving in the content server from a network device a key management block for the cluster, a unique data token for the cluster, and an encrypted cluster id; calculating a binding key for the cluster in dependence upon the key management block for the cluster, the unique data token for the cluster, and the encrypted cluster id; inserting a title key into a rights object defining rights for the broadcast encryption content; and sending the rights object to the cluster. In typical embodiments, the rights for content include an authorization for a play period and an authorized number of copies of the broadcast encryption content to devices outside the cluster.

摘要： Controlling delivery of broadcast encryption content for a network cluster from a content server outside the cluster that include receiving in the content server from the network device a key management block for the cluster, a unique data token for the cluster, and an encrypted cluster id and calculating a binding key for the cluster in dependence upon the key management block for the cluster, the unique data token for the cluster, and the encrypted cluster id. In typical embod0iments, calculating a binding key includes calculating a management key from the key management block for the cluster; calculating a content server device key from the management key and the content server device id; decrypting the encrypted cluster id with the content server device key; and calculating the binding key with the management key, the unique data token for the cluster, and the cluster id.

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.
