This proposal focuses on the design and modeling of secure wireless mesh networks(WMNs). The IEEE WMNs standard, 802.11s, is not mature enough to address security concerns of WMNs. To enhance the security of 802.11s WMNs, the first goal of this proposed research is to investigate methodologies of security and efficient techniques so as to make a single-operator WMNs secure and resilient to attacks. In this study, a generic security package will be studied to support fast authentication and exposure-resilient key management. A role-based access control model (RBAC) will be designed to support clients' authorization. A heterogeneity-aware framework for group key management will be studied for the single-operator WMNs. Future large-scale WMNs are expected to comprise numerous mesh networks, each administered by an independent network operator. Different network operators may collaborate to provide continuous connectivity to roaming users for supporting seamless services, such as voice-over-IP, e-conference, e-news, and online games. The second goal of the proposed research is to investigate methodologies of security techniques so as to make roaming in multi-operators WMNs seamless, secure, and efficient. To achieve this research objective, a new trust model is to be developed so that different mesh networks do not require establishing the roaming agreements and clients are no longer bound to any specific network operator. Instead, a client acquires a ticket from a third-party broker whereby to realize seamless roaming across mesh networks administrated by different operators. A secure and fast inter-operator handover scheme will be developed to support client's seamless crossing the boundary of mesh domain boundaries. A general role-based access control will be studied to ensure the authorization of mesh clients. An efficient billing protocol will be developed to foster node cooperation. This study, particularly the consideration and implementation of the fast handoff mechanism, and new trust- and role-based access control models, will be used as the direction and guidance for us to develop a systematic design methodology and to model wireless mesh networks for various applications.

本文主要研究安全无线网状网络（WMNs）的设计与建模。IEEE WMNs标准802.11s还不够成熟，无法解决WMNs的安全问题。为了提高802.11s无线网络的安全性，本研究的第一个目标是研究安全方法和有效技术，以使单运营商无线网络安全且抗攻击能力强。在本研究中，将研究一个通用的安全包，以支持快速身份验证和暴露弹性密钥管理。将设计基于角色的访问控制模型（RBAC）来支持客户机的授权。研究了单算子wmn组密钥管理的异构感知框架。未来的大规模wmn预计将包括许多网状网络，每个网状网络由一个独立的网络运营商管理。不同的网络运营商可以合作为漫游用户提供连续的连接，以支持无缝服务，例如ip语音、电子会议、电子新闻和在线游戏。本研究的第二个目标是研究安全技术的方法，以使多运营商无线网络中的漫游无缝、安全、高效。为了实现这一研究目标，需要开发一种新的信任模型，使不同的网状网络不需要建立漫游协议，客户端不再约束于任何特定的网络运营商。相反，客户端从第三方代理那里获得票证，从而实现跨由不同运营商管理的网状网络的无缝漫游。为支持客户端无缝跨越网格域边界，提出了一种安全、快速的运营商间切换方案。本文将研究一种基于角色的通用访问控制，以保证网格客户端的授权。将开发一种有效的计费协议，以促进节点合作。这项研究，特别是对快速切换机制的考虑和实现，以及新的基于信任和角色的访问控制模型，将为我们开发系统的设计方法和为各种应用建立无线网状网络模型提供方向和指导。
