摘要
分析当前密钥协商方案,讨论其安全性和攻击行为,并对GDH的安全性能和运算复杂度进行分析,根据安全性需要,给出了一种基于椭圆曲线的群密钥协商方案,该方案不仅提高实现效率并且可抵御主动攻击.
Group key agreement is studied in various field includiing security level, attacking ways, and complexity. In order to meet the demand of security and efficiency, a new group key agreement scheme is formulated in this paper, which is based on elliptic curve system, and vulnerable to active attackers.
