Abstract:
A method and a system for distributing an encryption key for service protection and content protection in a mobile broadcasting system are provided where a network generates a first encryption key when a broadcasting service is first provided to the terminal, and transmits a long term key message including the generated first encryption key to the terminal. Also, the network generates a second encryption key before the lifetime of a first access value pair expires, and transmits a long term key message including the generated second encryption key to the terminal.
