一种基于第三方认证的无线组密钥协商协议

Novel group key agreement protocol based on trusted third party for wireless network

提出一种基于第三方认证的组密钥协商协议,用于在无线Mesh网络环境下的移动用户间的协同工作。经过安全性分析和性能分析得出,新协议不仅可以对组用户提供私密性保护,而且协议参与者的身份得到认证,此外,每个成员的计算成本和通信量显著降低,提高了协议的执行效率。因此,该协议是无线Mesh网络环境下的一种新型、可靠的组密钥协商协议。

This paper proposed a novel group key agreement protocol based on trusted third party, applied in collaboration be- tween mobile users for wireless Mesh network. The security analysis and performance analysis show that, the protocol not only provides privacy protection for group members, but also authenticates all participants by adopting certificates. More important, in the proposed protocol, the computation cost and traffics for each group member are largely reduced to improve the implemen- tation efficiency of the protocol. Therefore, the protocol is a novel, reliable group key agreement protocol, and it is well suited for wireless Mesh network.
