摘要： A process composes a content license for a set of content. The content license has a static portion and a dynamic portion. Further, the process inserts a master key into the static portion. In addition, the process inserts a plurality of content rule sets of values into the dynamic portion and composes a unique content encryption key for each segment of content associated with one of the content rule sets of values as each of the content rule sets of values is sequentially received during recording of the content. The unique content encryption key is based on the master key and at least a subset of the content rule set of values for a corresponding segment of the content. The unique content encryption key is utilized for encryption of each segment of the content to generate a plurality of encrypted content segments for storage on the storage medium.

摘要： A method and apparatus are for transferring a client device certificate and an associated encrypted client private key to a client device from a secure device. The secure device receives over a secure connection, a secure device certificate, a secure device private key and a plurality of client device certificates. Each client certificate is associated with a bootstrap public key but is not assigned to any particular client device. A plurality of encrypted client private keys is also received. Each of the encrypted client private keys comprises a client private key associated with one of the client device certificates encrypted with the bootstrap public key. The plurality of client device certificates is stored. The encrypted client private keys are stored in double encrypted protected form. A client device certificate and an associated encrypted client private key are transferred to a client device that has successfully registered with the secure device.

摘要： A process may be utilized by a DVR. The process characterizes a set of content as a plurality of segments as the set of content is received. Each of the segments has a segment length according to a predetermined time interval. Further, the process encrypts each of the segments with a corresponding content encryption key to generate a plurality of encrypted segments. The corresponding content encryption key for each of the segments is generated by the DRM component. In addition, the process stores each of the encrypted segments for playback with trick play features in accordance with an expiration content rule having a time limit on the temporary playability of the set of content.

摘要： A digital rights management architecture for securely delivering content to authorized consumers. The architecture includes a content provider and a consumer system for requesting content from the content provider. The content provider generates a session rights object having purchase options selected by the consumer. A KDC thereafter provides authorization data to the consumer system. Also, a caching server is provided for comparing the purchase options with the authorization data. The caching server forwards the requested content to the consumer system if the purchase options match the authorization data. Note that the caching server employs real time streaming for securely forwarding the encrypted content, and the requested content is encrypted for forwarding to the consumer system. Further, the caching server and the consumer system exchange encrypted control messages (and authenticated) for supporting transfer of the requested content. In this manner, all interfaces between components are protected by encryption and/authenticated.
摘要翻译：数字版权管理架构，用于将权限安全地传递给授权消费者。该架构包括内容提供商和用于从内容提供商请求内容的消费者系统。内容提供商生成具有由消费者选择的购买选项的会话权限对象。 KDC此后向消费者系统提供授权数据。此外，还提供了一个缓存服务器，用于将购买选项与授权数据进行比较。如果购买选项与授权数据匹配，则缓存服务器将所请求的内容转发到消费者系统。请注意，缓存服务器采用实时流式传输安全地转发加密的内容，并且所请求的内容被加密以转发到消费者系统。此外，缓存服务器和消费者系统交换加密的控制消息（并被认证）以支持所请求的内容的传送。以这种方式，组件之间的所有接口都受到加密和/或认证的保护。
