摘要: 无线Mesh网络的现有认证协议不支持双向802.1X的认证端口开放.基于密钥交换协议交换,利用“通用可组合”安全模型的组合特性与信任传递技术,在应答消息中安全结合反向认证信息,实现了满足Mesh网络双向认证需求的认证协议,不仅具有可证明的安全性,且通信开销较原协议降低60%以上.

Abstract: The authentication protocol of Wireless Mesh Networks does not support 802.1X-based mutual authentication. Based on Diffie-Hellman(DH) exchange and making use of the combination characteristic of the Universally Composable(UC) security model and trust transfer, a new authentication protocol is proposed. Piggybacking opposite direction authentication messages in response, this protocol not only provides two-way authentication for Wireless Mesh Networks but also affords provably UC-security. Furthermore,compared with the original scheme, the communication cost decresses by 60%.

Key words: mesh networks, UC-security, authentication protocol, provable security
