摘要：
A method and apparatus for providing a broadcast service in a communication system is provided. The method includes creating a seed key pair including a first key and a second key, transmitting the seed key pair to a terminal to which the broadcast service is to be provided, creating a certain number of encryption keys using the seed key pair, the certain number corresponding to a lifetime of the seed key pair, encrypting broadcast service data for the lifetime using the encryption keys, and broadcasting the encrypted broadcast service data.
