Secure and Efficient ID-Based Group Key Agreement Fitted for Pay-TV
While broadcasting services have witnessed substantial technological developments which are represented by group-oriented applications, an important on-going challenge is to design secure and efficient group key management. A number of protocols targeted for Pay-TV systems have been developed and proposed. However, most of the forward-secure protocols published up to now are not suitable for practical application in mobile devices. In this paper, we propose a secure and efficient two-round protocol which would fit well in Pay-TV systems and, additionally, in mobile environments covering internet stock quotes, audio and music deliveries, software updates and so on. Also we prove its security. The proposed protocol is of simplicity and efficiency and provably secure.
