中文摘要：
提出一个适用于无线移动环境的高效的群认证密钥交换协议。协议具有如下特点：首先,计算的非对称性。协议将大部分的计算放置在群组中的某一个计算能力较强的设备上,从而减少了其它计算能力较弱的设备所需要承担的计算量,因此,此协议很好地适用于计算能力上非对称的无线移动环境。其次,此协议将内部人攻击作为研究目标。除了基本的会话密钥安全性以外,此协议适用的安全模型考虑了内部人攻击。最后,协议的安全性得以严格的形式化证明。
英文摘要：
A feasible group authenticated key exchange protocol is proposed in the wireless mobile environment.The proposed protocol has two distinguishing features.The first is the asymmetry of computation;means that protocol allows a powerful node to shoulder more computational burdens and the others can perform less.So this protocol can be better adapted to a wireless mobile environment,a computationally asymmetric one.Meanwhile,besides the basic security of the session key this protocol takes the insider attack into considerations.Finally,it is shown that the protocol is provably secure in formal model.
