摘要： Content delivered to client device over an Internet Protocol Multimedia Subsystem (IMS)-based network is protected through a digital rights management (DRM) scheme that leverages IMS service and access infrastructure, such as the IMS core. After authentication and selection of content to be played for the user, the network identifies a key management system having keys for decrypting the selected content. A bootstrapping service function participates in an application-level authentication of the client device to establish a secure communication channel between the key management system and the client device. The key management system responds to a content key request received from the client device by providing a content key via the secure communication channel. The network can then stream content to the client device, which decrypts it using the content key.

摘要： A Service Key Delivery (SKD) system for delivering a service keys to client devices in a communications network. The delivered service keys are operable to be used to decrypt an encrypted key operable to be used to decrypt an encrypted digital content. The SKD system includes a data input interface for receiving a distribution time frame for the keys and a listing of client device identifications. The SKD system also includes a scheduling module to partition at least part of the distribution time frame into a number of time slots in which the number may be based on a variety of factors. The scheduling module assigns the time slots in the partitioned part of the distribution time frame to the client devices based on the identifications in the listing. The SKD system also includes a message generator configured to send key delivery messages to the client devices.

摘要： A method of viewing a content item is provided. The method includes receiving an encrypted content item and a network address of a key management system from a primary client device over a communications network. A session key is obtained over the communications network and the primary client device is notified that the session key has been obtained.
