Abstract: The present invention relates to a method and an apparatus for efficiently transmitting a conditional access message, which enable a conditional access to a broadcasting service in a DMB system. A terrestrial DMB transmitting system which supports a conditional access includes: a conditional access system (CAS) server which generates information about the transmission cycle and traffic of an entitlement control message (ECM) related to the reception authority of a DMB service; a DMB video scrambler which calculates the number of streams necessary for transmitting the ECM based on the information about the transmission cycle and traffic of the ECM; and a DMB video encoder which generates null packets as many as the calculated number of the streams. The DMB video scrambler generates an ECM packet by inserting the ECM into a payload which is arranged in transport streams for the null packets.
