Idetity based group key agreement from bilinear pairing
Wang Liming, Wu Chuankun · Wuhan University Journal of Natural Sciences · 2006
We present a provably secure authenticated tree based key agreement scheme for multicast. There is a wide variety of applications that can benefit from using our scheme, e. g., pay-Tv, teleconferencing, software updates. Compared with the previous published schemes, our scheme provides group member authentication without introducing additional mechanism. Future, we give the security proof of our scheme under the random oracle model.
