A method and apparatus for managing tokens for Digital Rights Management (DRM) in a terminal are provided. In the method, at least one token is acquired from a Rights Issuer (RI), and the token is moved to a Secure Removable Media (SRM) through a token move request message. The token can be shared by several terminals.

Method and apparatus for managing tokens for digital rights management

A method is provided for controlling access to a resource of a Remote User Interface (RUI) server in an RUI client of an RUI system. The method includes sending a request for an RUI page for controlling the resource to the RUI server and receiving the RUI page, generating a connection to a Mutual Exclusion (MUTEX) of the RUI server, which corresponds to the resource, using the received RUT page, and sending a request for MUTEX locking for restricting access to the resource to the RUI server.

Method and apparatus for controlling access to resources in remote user interface service

A terminal and method for receiving a broadcast service by the terminal in a broadcast system are provided. The method includes performing a registration procedure for subscription and reception of the broadcast service through a Browser And Content Mobile Broadcast (BSCAST) Subscription Management (BSM) responsible for managing subscription information; receiving a Long Term Key Message (LTKM), including key information for encryption of the broadcast service, generated from the BSM; receiving a completed Short Term Key Message (STKM), the completed STKM being generated by performing Message Authentication Code (MAC) processing on a partially created STKM; receiving, from a Broadcast Service Distribution/Adaptation (BSD/A) which is responsible for transmitting the broadcast service, an encrypted broadcast service which is encrypted by a Traffic Encryption Key (TEK) for deciphering the broadcast service; and deciphering the encrypted broadcast service by the TEK obtained using the LTKM and the completed STKM.

Method and system for protecting broadcast service/content in a mobile broadcast system, and method for generating short term key message therefor

A method of informing a selected CN operator from a UE to a RAN in an NS system where a plurality of CN operators shares the RAN is provided. Upon request of transmission of an IDT, the UE acquires a CN operator ID selected from a multi-ID list broadcasted from a cell in which an RRC connection has been established, and transmits an IDT message with the selected CN operator ID to the RAN. Upon receipt of the IDT message, the RAN determines whether the IDT message includes a selected CN operator ID. In the presence of the selected CN operator ID, the RAN stores the selected CN operator ID in a UE context. In the absence of the selected CN operator ID, the RAN reads a stored selected CN operator ID from the UE context. The RAN then selects a CN operator using the selected CN operator ID.
