摘要： A method and apparatus for transmitting/receiving encryption information in a mobile broadcast system providing broadcast service (BCAST) are disclosed. In the mobile broadcast system, a broadcast (BCAST) Service Distribution/Adaptation (BSD/A) unit comprises a transmitter for transmitting a Registration Key Material (RKM) request message for requesting delivery of an RKM for registration of the BCAST service of a terminal to a BCAST Subscription Management (BSM) unit managing subscriber information of the terminal, and a receiver for receiving an RKM request response message from the BSM unit. The RKM request message includes an identifier (ID) of the BCAST service, and the RKM request response message includes the ID of the BCAST service and the RKM. The transmitter transmits a Long-Term Key Message (LTKM) request message for requesting delivery of an LTKM provided to the terminal during subscription of the BCAST service to the BSM unit.

摘要： A roaming service method in a mobile broadcasting system and a system thereof are provided. A terminal receives a service guide from a corresponding visited service provider (Visited SP) when the terminal moves to a roaming area. The terminal transmits a roaming request message for requesting a purchase item allowable for individual services to a home service provider (Home SP) based on the received service guide. Upon receipt of the roaming request message, the Home SP negotiates roaming availability and allowable scope for each individual service with the Visited SP where the terminal is located, based on the roaming request message. The Home SP transmits the roaming availability and allowable scope for the individual service, negotiated with the Visited SP, to the terminal.

摘要： A method and apparatus are provided for controlling a Remote User Interface Client (RUIC), on which a remote user interface is displayed, through another RUIC. A message including control information that indicates a control action corresponding to a user input at the other RUIC is received at the RUIC from the other RUIC. The RUIC determines whether the control information is predefined information or undefined information. When the control information is predefined information, the control information is delivered from a web server of the RUIC to an application of the RUIC, and a control operation corresponding to the control information is executed by the application. When the control information is undefined information, the received control information is delivered from the web server to the application through a remote control plug-in in the RUIC to execute the control operation corresponding to the control information by the application.

摘要： Disclosed is a method for generating a Short Term Key Message (STKM) for protection of a broadcast service being broadcasted to a terminal in a mobile broadcast system. The method includes transmitting, by a Broadcast Service Subscription Management (BSM) for managing subscription information, at least one key information for authentication of the broadcast service to a Broadcast Service Distribution/Adaptation (BSD/A) for transmitting the broadcast service, generating, by the BSD/A, a Traffic Encryption Key (TEK) for deciphering of the broadcast service in the terminal and inserting the TEK into a partially created STKM, and performing, by the BSD/A, Message Authentication Code (MAC) processing on the TEK-inserted STKM using the at least one key information, thereby generating a completed STKM.
