摘要： A method and an apparatus for sharing a license between SRMs are disclosed. The method includes: a DRM agent obtains the license from a first SRM, and sets the license to a forwarding state locally; the DRM agent deducts one right of sharing the license; and the DRM agent sends the license to a second SRM. In the prior art, one moving right is deducted when the license moves from SRM1 to the device, and the other moving right is deducted when the license moves from the device to SRM2. By contrast, in the technical solution under the present invention, the license forwarded by the DRM agent is set to the forwarding state, and only one sharing right needs to be deducted, and therefore, the consumption of the sharing rights is reduced and the subscriber's rights are protected.
摘要翻译：公开了一种用于在SRM之间共享许可证的方法和装置。该方法包括：DRM代理从第一SRM获取许可证，并将许可证本地设置为转发状态; DRM代理人扣除共享许可证的一项权利; 并且DRM代理将许可证发送到第二SRM。在现有技术中，当许可证从SRM1移动到设备时，一个移动权利被扣除，并且当许可证从设备移动到SRM2时，另一移动权利被扣除。相比之下，在本发明的技术方案中，由DRM代理转发的许可证被设置为转发状态，并且仅需要扣除一个共享权，因此减少共享权限的消耗，权利得到保护。

摘要： A method for importing or moving a rights object (RO) is provided, 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.
摘要翻译：提供了一种用于导入或移动权限对象（RO）的方法，权利发行者（RI）接收向目标设备导入或移动RO的请求消息，该请求消息包括由目标的公开密钥封装的密钥信息设备; RI根据请求消息生成RO，RO包括由目标设备的公钥封装的密钥信息; 并且RI为目标设备提供RO。还提供RI。在本发明中，由RI提供由目标设备的公共密钥封装的密钥信息，并且真实密钥从RI隐藏，使得不信任RI不能为除其他设备之外的其他设备生成非法RO 目标设备，从而提高通过RI进口或移动RO的安全性。

摘要： The present invention discloses a method for transferring licenses, a device for issuing licenses, and a communication system, and relates to the Digital Rights Management (DRM) technology. The method includes: the first issuing device receives a request of transferring a license issued by the second issuing device; the first issuing device transfers the license after determining that a relationship is set up with the second issuing device. The license issuing device includes: a receiving module, a setup module, a determining module, and a sending module. The communication system includes: a first issuing device, a second issuing device, and a device requesting to transfer a license. Through the present invention, an issuing device may transfer the licenses issued by other issuing devices, thus improving the flexibility of transferring the licenses.
