摘 要：
针对Bae Eun Jung协议需要2轮广播的问题,提出了一个有效的基于身份的群密钥协商协议。新协议适于动态群,当群中有用户加入或退出时仅需计算2次MB协议,而且消息广播只用了1轮。与Bae EunJung协议相比,降低了通信量。

摘 要：
The paper presents an efficient identity-based key agreement that is inspired on an efficient group key agreement by Bae Eun Jung.This protocol is suitable for dynamic group and MB agreement only needs to be calculated twice when new users enter or withdraw.The broadcast of our protocol needs only one round.
