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.
