✦ Synopsis

Group key agreement is the core of secure group communication. In wireless networks, the privacy problem becomes more crucial and urgent for mobile users due to the open nature of radio media. In this paper, we proposed a novel group key agreement protocol based on trusted third Party, applied in collaboration between mobile users for wireless Mesh network. The security verification (PCL logic) and performance analysis show that, our 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 implementation efficiency of the protocol. Therefore, our protocol is a novel, reliable group key agreement protocol, and it is well suited for wireless mesh network.
