METHOD AND DEVICE FOR MANAGING AUTHORIZATION OF RIGHT OBJECT IN DIGITAL RIGHTS MANAGEMENT

摘要

A method and a device for managing a right in digital rights management are provided to perform an RDP drop domain protocol between an RI(Rights Issuer) and a DA/DEA(Domain Authority/Domain Enforce Agent), thereby stopping generation and issuance rights of a domain RO(Rights Object) about a specific domain. A DA/DEA(300) includes the first information for stopping an issuance right of a domain RO about a specific domain to transmit a trigger message. The DA/DEA receives a drop domain request message including the second information about stopping an issuance right of the domain RO from the RI. The DA / DEA transmits a drop domain response message including the third information about an issuance right of the domain RO to the RI.
