中文摘要： 无线网状网(WMN)是下一代移动网络的重要组成部分，适合于宽带无线骨干传输环境。接入安全是WMN 有待解决的关键技术问题之一，现有安全接入方案无法满足多运营商网络环境下隐私保护的高效统一安全接入需求。本课题以多运营商WMN 为研究对象，从分析多运营商WMN 环境特点及移动用户接入特征入手，首先建立面向域并支持多运营商协作的分级接入安全体系并将其与层次型微移动管理框架整合；联合公钥基础设施与身份密码系统构建混合信任模型；面向移动用户接入过程中的隐私保护需求，提出假名与票证相结合的身份管理机制及身份认证关键技术；进而设计支持非交互式密钥协商和隐私保护的分布式双向接入认证协议。此外，课题将通过实验系统搭建和原型系统部署等手段验证相关方案的有效性、高效性和安全性。课题的成功实施将能够有效地解决多运营商WMN 接入安全问题，对WMN 的大范围部署起到积极推动作用。

英文摘要： Wireless mesh network (WMN) has emerged as a critical component of next-generation mobile network and is adapt to broadband wireless backbone.Access security is a key obstacle in WMN. While the literature proposals can not cope well with the privacy concerns and the efficient unified secure access requirements from mobile users in multi-operator scenarios. Aiming at establishing secure and privacy-preserved access procedure for multi-operator WMN, this project first sets up a hierarchical security architecture, based on domain that supports cooperations among operators, according to the particular characteristics of multi-operator WMN and mobile users' access behavior. The architecture is also integrated into hierarchical mobility management framework to gain more efficiency. A hybrid trust model is set up under the help of the marriage between PKI and IBC. In terms of the privacy concerns during mobile user's access, a novel identity management mechanism as well as authentication techniques are designed based on the combination of allias and ticket. Thus we further propose a distributed and privacy-preserved mutual authentication protocol which equipts with non-interactive key agreement scheme. Moreover, we will validate and demonstrate the availability, efficiency, as well as security of our proposal through b
