摘要
组认证密钥交换协议允许两方或多方用户通过公开的信道协商出共享的组会话密钥。针对非平衡无线网络中用户计算能力强弱不等的情况,该文提出一种适用于非平衡无线网络的组组认证密钥交换协议。该协议不但可以抵抗临时密钥泄露所带来的安全隐患,而且任意两个组中用户可以根据需要使用先前组通信消息计算独立于组会话密钥的两方会话密钥。与已有非平衡网络组密钥交换协议相比,该协议具有更高的安全性和实用性并且在随机预言模型下是可证安全的。
Group Authenticated Key Exchange（GAKE） protocols allow two or more parties to generate a common group session key in public channel.Considering users＇ different computing power,a new GAKE protocol is proposed for imbalanced wireless network and its security is proved in the random oracle model.In additional,the protocol can resist ephemeral key compromise attack and any two users can generate a two-party session key using the information of group stage.Compared with other GAKE protocols for imbalanced wireless network,the proposed protocol has stronger security.
