    Abstract: DTV services are getting widespread use, requiring service providers to have
    effective methods for remotely configuring and managing DTV set-top boxes (STBs).
    Solutions for such remote management are becoming standards-based. In this paper,
    we first propose a secure frequency billing service in DTV broadcasting. The billing
    system can provide users a more convenient way for payment. For charging in traditional
    television, many billings are half-yearly done. However, in the proposed protocol, users
    can watch TV in their free time and take single billing method. As a result, users can
    choose the most suitable billing methods according to their requirements. Moreover, the
    proposed protocol is more efficient than other previously proposed protocols by eliminating
    exponentiation operations which are time-consuming computations. Finally, our protocol
    not only provides better way for DTV charging but also prevents two common serious
    problems in DTV broadcasting such as smart card cloning and replay attacks.
