摘要： A method for exporting permission is provided to solves the problem that the permission can not be exported multiple times among several DRM systems in the prior art; the method includes that: determining that a license is permitted to be exported to a system that a target device belongs to; determining whether an export permission in the license is permitted to be exported; and exporting the export permission in the license to the target device if the export permission in the license is permitted to be exported, which enables the target device to export the license to another device. A terminal apparatus, a server and a communication network are also disclosed.

摘要： A method for license interaction and interaction recovery after interruption overcomes the problems of mobility loss and waste of rights of the license due to interruption of communication during the license interaction. This method includes: when a first device and a second device interact on license information, both devices record the interaction related information; after the interaction is interrupted and the connection is re-established, the first device and the second device continue the interaction when determining that the interaction is uncompleted according to the recorded information. A communication device and a digital rights management (DRM) system are also disclosed.

摘要： A method for importing or moving a rights object (RO) is provided, which includes the following steps. A rights issuer (RI) receives a request message of importing or moving an RO to a target device, the request message including key information encapsulated by a public key of the target device; the RI generates the RO according to the request message, the RO including the key information encapsulated by the public key of the target device; and the RI provides the RO for the target device. An RI is also provided. In the present invention, the key information encapsulated by the public key of the target device is provided for the RI, and the real key is hidden from the RI, such that the un-trust RI cannot generate the illegal RO for other devices except the target device, thereby enhancing the security of importing or moving the RO through the RI.

摘要： A system for issuing a license includes a Content Issuer (CI) configured to receive a Cooperate-RORequest from a Rights Issuer (RI). The CI encapsulates, according to the information carried in the Cooperate-RORequest, content related information by using a key of a destination entity to obtain an encapsulation key, and generates a Message Authentication Code (MAC) on part of information of a license. The CI sends the generated MAC and obtained encapsulation key to the RI, so that the RI sends the license that includes the MAC and the encapsulation key to the destination entity.
