    Abstract: 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.

    Abstract: A digital rights management method (250) and apparatus (10) for protecting digital content enables a flexible pricing model to be implemented that accounts for a subscriber's current subscription type. The digital rights management method (250) provides (251) a purchase option element for each protected digital content. This purchase option element includes specifying a set of content usage rules (which may or may not allow for the content to be saved persistently). The digital rights management method (250) also includes specifying (252) a cost for each protected digital content associated with the set of content usage rules. The digital rights management method (250) also includes specifying (253) a subscription group for the protected digital content associated with a set of content usage rules, which subscription group includes one or more subscription services and one or more associated incremental discounts for the protected digital content based on the one or more associated subscription services.

    Abstract: 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 (115) remotely located from the consumer (116) rather than locally at the end user site. In a first aspect, in a computing network having a content provider (102), a key distribution center, a caching server (115) and a client (116) 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.

    Abstract translation: 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。 访问权限在远离消费者（116）的缓存服务器（115）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（102），密钥分配中心，缓存服务器（115）和客户机（116）的计算网络中，控制客户端从缓存中访问实时数据流的方法 服务器，被披露。 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进行比较，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。

    Abstract: A method and system generates and distributes unique cryptographic device keys. The method includes generating at least a first device key and encrypting the first device key with a first encrypting key to produce a first encrypted copy of the device key. The method also includes encrypting the first device key with a second encrypting key to produce a second encrypted copy of the device key. The second encrypting key is different from said first encrypting key. The first and second encrypted copies of the device keys are associated with a device ID identifying a computing device being manufactured. The second encrypted copy of the device key is loaded onto the computing device. The first encrypted copy of the device key and the device ID with which it is associated are stored onto at least one server for subsequent use after the computing device has been deployed to a customer.

    Abstract: A method of authentication and authorization over a communication system is provided. The method performs a first authentication of a device based on a set of device identity and credentials. The first authentication includes creation of a first set of keying material. The method also includes performing a second authentication of a subscriber based on a set of subscriber identity and credentials. The second authentication includes creation of a second set of keying material. A set of compound key material is created with a key derivation mechanism that uses the first set of keying material and the second set of keying material. A binding token is created by cryptographically signing at least the device identity authenticated in the first authentication and the subscriber identity authenticated in the second authentication using the set of compound keying material. The signed binding token is exchanged for verification with an authenticating and authorizing party.
