METHOD, DEVICE, AND SYSTEM FOR ISSUING LICENSE |
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. |
