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： 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.

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.
