摘要： An IMS system includes an IMS initiator user entity. The system includes an IMS responder user entity that is called by the initiator user entity. The system includes a calling side S-CSCF in communication with the caller entity which receives an INVITE having a first protection offer and parameters for key establishment from the caller entity, removes the first protection offer from the INVITE and forwards the INVITE without the first protection offer. The system includes a receiving end S-CSCF in communication with the responder user entity and the calling side S-CSCF which receives the INVITE without the first protection offer and checks that the responder user entity supports the protection, inserts a second protection offer into the INVITE and forwards the INVITE to the responder user entity, wherein the responder user entity accepts the INVITE including the second protection offer and answers with an acknowledgment having a first protection accept. A method for supporting a call by a telecommunications node.

摘要： Disclosed is a DRM device and method for providing secure linking to a user identity. A first request is sent to a subscriber identity module. A message is received from the subscriber identity module via a secure authenticated channel. The message comprises at least a a master key identifier, a random number, and a derived key. In response to the message, a second request is sent to a DRM server. The second request comprises at least a master key identifier, the device identifier, and a random number. Also disclosed is a DRM server and method for providing secure linking to a user identity. A first request is received from a DRM device. The first request comprises at least master key identifier, a device identifier, and a random number. The DRM device is authenticated. A second request for an application specific key is sent to a trusted key management server. The second request comprises at least a master key identifier. At least a key is received from the trusted key management server. A derived key is determined from the key received from the trusted key management server based at least on the device identifier and the random number. A challenge/response scheme is used to determine whether the derived key of the DRM server matches a derived key of the DRM device.

摘要： Systems and methods according to the present invention address this need and others by providing methods and systems for translating media encrypted by various Digital Rights Management (DRM) techniques. This allows end user equipment to receive media in an IMS/IPTV environment when the end user equipment uses a DRM that is different from the media server which is providing the desired media in both unicast and multicast applications.

摘要： A method and arrangement is disclosed for managing session keys for secure communication between a first and at least a second user device in a communications network. The method is independent of what type of credential each user device implements for security operations. A first user receives from a first key management server keying information and a voucher and generates a first session key. The voucher is forwarded to at least a responding user device that, with support from a second key management server communicating with the first key management server, resolves the voucher and determines a second session key. First and second session keys are, thereafter, used for secure communication. In one embodiment the communication traverses an intermediary whereby first and second session keys protect communication in their respective leg to said intermediary.

摘要： A system for generation of processed data for use in third party relationship monitoring is described. The system includes a communications system providing services to subscribing users. The communications system includes a rules database for storing rules, a data mining agent for mining and storing data relating to subscribing users, a content generator for generating protected user-related data from the mined data and communicating said user-related data over an interface, and a rights object generator for generating a usage rights object in response to the rules stored in the rules database and communicating said usage rights object over the interface. A tamper proof processing arrangement is connected to the interface. The tamper proof processing arrangement receives the user-related data and usage rights object from the communications system and processes the user-related data under control of the usage rights object. A signal output generator generates an output signal representative of processed data received from the processing arrangement.
