Abstract: A method and apparatus for providing a broadcast service in a communication system is provided. The method includes generating a key pair comprising a first key and a second key, generating at least one of forward encryption keys by applying a forward hash chain to the first key, generating at least one of reverse encryption keys by applying a reverse hash chain to the second key, generating at least one of encryption keys using the at least one of forward encryption keys and the at least one of reverse encryption keys, encrypting broadcast service data using the at least one of encryption keys, and broadcasting the encrypted broadcast service data.
