Recently, the Pay-TV broadcasting system becomes one of the popular applications because of the advance of modern network technique. The conditional access system is the essential function to provide the channel protection in Pay-TV broadcasting system. It ensures that only the authorized subscribers can precisely receive the TV program and the service provider can charge the subscribers according to their subscription. Several conditional access systems have been proposed for different business models such as pay-per-channel, pay-per-view, and flexible pay-per-channel. In this paper, we define a new business model named Flexible Pay-Per-Group and design a conditional access system for it. Compared with the previous works, subscribers in Flexible Pay-Per-Group still have sufficient flexibility. Besides, through our analysis and evaluation, the proposed conditional access system is efficient. Consequently, it can be applied on a large scale Pay-TV system with lots of subscribers and channels.
