摘要： A system and method for transmitting/receiving encryption information in a mobile broadcast system supporting broadcast service (BCAST) are provided. In the mobile broadcast system, a BCAST Subscription Management (BSM) manages subscriber information of a terminal, and transmits to a BCAST Service Distribution/Adaptation (BSD/A) a first delivery message including a Registration Key Material (RKM) provided for registration of the broadcast service of the terminal and including at least one service or content's identifier. The BSD/A transmits to the BSM a first delivery confirmation message including information indicating success/fail in receipt of the first delivery message, and transmits the RKM to the terminal.

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.
