Abstract: A rights objects acquisition method of a mobile terminal in a digital right management system is provided for acquiring multiple rights objects in a composite manner. An objects right acquisition method of a mobile terminal may include generating, in response to a group rights object (RO) acquisition command, a group rights object acquisition request with content identifiers assigned to individual contents corresponding to the rights objects indicated by the group rights object acquisition command, sending the group rights object acquisition request to a rights issuer; and receiving an group rights object acquisition response containing rights object identifiers assigned to the rights objects from the rights issuer. The present invention streamlines the RO acquisition process, especially when acquiring multiple ROs.

Abstract: A DRM/CAS service device is provided. The device includes a registration service server that authenticates a device and an STP of the device and generates a device-based context according to a registration request and a DRM/CAS service request from the device; a DRM/CAS service server that receives the device-based context and generates DRM/CAS security contexts; and a DRM/CAS SW service server that receives the DRM/CAS security contexts, generates the DRM/CAS software package including the DRM/CAS security contexts and DRM/CAS software, and enables the DRM/CAS software package to be provided for the device. The DRM/CAS service device reduces the amount of processing and simplifies the process by installing and using content and service protection software, that is, DRM/CAS software by using a security context.
