    Abstract: Provided is a transmitting/receiving method and device for providing a conditional access broadcasting service. A transmitting method for providing a conditional access broadcasting service includes generating a control word (SI 10) for scrambling by- encoding a conditional access subscriber's, and changing the encoded data into an entitlement control message and an entitlement management message including the data generated by classifying the conditional access subscriber and a non-subscriber by activating the data (S120). Also, the method includes generating a final stream by multiplexing (S130) the entitlement control message, the entitlement management message, and a base stream for a first broadcasting service (SI 40), generating a base layer frame and an enhancement layer frame (SI 50) based on the final stream and an enhancement layer stream for a second broadcasting service, generating a broadcasting signal by hierarchically modulating (SI 60) the base layer frame and the enhancement layer frame, and transmitting the broadcasting signal.
