| Abstract: | A digital rights management system is presented to prevent the pirates from pirating the digital content of IPTV. The schemes for realizing the key modules of the system such as video files eneryption/ decryption at the servers terminal and licenses acquiring/operating at the clients terminal are also proposed. The system is designed to he very concise by employing the license mechanism both in the content eneryption server and in the clients. The secret data of the clients like private keys and operation logs are stored and operated in the inner of the smartcard, by which our system gets its characteristic of higher security. |
