CAREER: Scalable, Robust and Secure Group-Oriented Services for Wireless Mesh Networks

无线网状网络作为一种有前途的、健壮的、低成本的网络架构正在兴起，它能够提供更大的覆盖范围和更大的带宽，从而提高服务质量和信息可用性。在无线网状网络上提供的许多分布式应用程序使协作和信息共享成为可能。此类应用程序受益于可伸缩、健壮且安全的组服务，例如一对多或多对多多播和分布式数据访问。反过来，组服务需要基础设施协议（如路由）或安全机制（如身份验证、访问控制和密钥管理）的支持。该项目的目标是在无线网状网络的背景下推进最先进的面向群体的服务。该项目提出了分布式问题的新公式，捕捉了无线网状网络的特殊性以及安全性、可用性和可扩展性之间的相互作用。研究了跨层设计作为构建安全网络服务的新范式的可行性和局限性。创新成果包括可扩展的一对多和多对多无线多播协议，为高效的组通信提供支持；可扩展的数据共享算法，对恶意行为具有鲁棒性；高吞吐量、鲁棒性和安全路由，帮助应用程序实现高性能、可扩展的密钥管理协议和身份验证机制，实现分散的基础设施访问服务。该项目有助于下一代安全系统设计师的教育，在分布式系统、安全和无线网络研究领域之间产生互动。

Cristina Nita-RotaruPurdue0545949AbstractWireless mesh networks are emerging as a promising robust low-costnetwork architecture able to provide increased coverage and largerbandwidth, resulting in higher quality of service and informationavailability.Many distributed applications provided on wireless mesh networks enablecollaborations and sharing of information. Such applications benefitfrom scalable, robust and secure group services such asone-to-many or many-to-many multicast and distributed data access.Group services, in turn, require support from infrastructure protocolssuch as routing, or security mechanisms such as authentication, accesscontrol and key management.The goal of this project is to advance state-of-the-art group-orientedservices in the context of wireless mesh networks. The project presentsnew formulations of distributed problems capturing the particularities ofwireless mesh networks and the interactions between security, availabilityand scalability. It also studies the viability and limitations of cross-layerdesign as a new paradigm of building secure network services. Innovativeresults consist of scalable one-to-many and many-to-many wirelessmulticast protocols that provide support for efficient group communication, scalabledata sharing algorithms that are robust to malicious behavior,high-throughput, robust and secure routing that assist applications to achievehigh-performance, scalable key management protocols and authenticationmechanisms enabling decentralized infrastructure access services.This project contributes to the education of the next generation of securesystems designers, generating interactions between the distributedsystems, security and wireless networks research areas.
