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： A process may be utilized by the DVR. The process receives a plurality of segments of a set of content and a plurality of corresponding content rule sets. Further, the process provides one or more instructions to record and encrypt the plurality of segments of the set of content on a storage medium. In addition, the process provides the plurality of content rule sets to the DRM component to be inserted into a locally generated and secured content license associated with the encryption of the set of content. The secured content license includes a master key and a list of the plurality of corresponding content rule sets that have been received in order of reception. The process receives a plurality of marker tokens from the DRM component in order to facilitate trick mode playback.

摘要： A session rights object and authorization data are used for defining a consumer's access right to a media content stream. The access rights are determined at a caching server remotely located from the consumer rather than locally at the end user site. In a first aspect, in a computing network having a content provider, a key distribution center, a caching server and a client, a method for controlling client access to a real-time data stream from the caching server, is disclosed. The method includes receiving, by the client, a session rights object from a content provider, the session rights object defining access rules for accessing the real-time data stream; receiving, by the client, authorization data from the key distribution center, the authorization data defining the client's access rights to the real-time data stream; forwarding to the caching server the session rights object and the authorization data; comparing, by the caching server, the session rights object with the authorization data to determine client authorization; and if the client is authorized, streaming, by the caching server, the real-time data stream to the client.
摘要翻译：会话权限对象和授权数据用于定义消费者对媒体内容流的访问权限。访问权限在远程位于消费者的缓存服务器上确定，而不是在最终用户站点本地。在第一方面，在具有内容提供商，密钥分配中心，高速缓存服务器和客户端的计算网络中，公开了一种用于控制来自高速缓存服务器的客户端对实时数据流的访问的方法。该方法包括从客户端接收来自内容提供商的会话权限对象，会话权限对象定义用于访问实时数据流的访问规则; 由客户端从密钥分配中心接收授权数据，定义客户端对实时数据流的访问权限; 转发到缓存服务器会话权限对象和授权数据; 通过缓存服务器比较会话权限对象与授权数据，以确定客户端授权; 并且如果客户端被授权，则通过缓存服务器流式传输到客户端的实时数据流。

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.
