Kan Zhou, Changsheng Wan, Aiqun Hu, Yubo Song · 2010
This paper presents a novel group key management for group security. It uses an elliptic curve based mechanism to distribute group key to the receivers. Its correctness is proved by security analyze. In the group key management process, our scheme requires fewer transmissions during re-key process than currently used LKH scheme, while still enjoys storage efficiency and computation efficiency.
