This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This project determines the fundamental limits of network secrecy from a network coding perspective, and then applies this theory to improve security guarantees in peer-to-peer and wireless networks. As network coding gains prominence as an important strategy for both wired and wireless networks, the project identifies both the advantages and vulnerabilities from using network coding. Subsequently, the effort develops a design methodology that exploits the advantages while carefully compensating for the vulnerabilities. This project analyzes networks under both outsider and insider attacks. Specifically, coding mechanisms are developed to combat an external eavesdropper. Also, a combination of cryptographic and information-theoretic tools are used to combat internal modification attacks on the network. The results are then used in two case studies: eavesdropper attacks on wireless mesh networks and pollution attacks on P2P content distribution systems. Secure network coded systems, once well understood, can greatly impact how networks are designed and deployed. Nearly every network setting (wireless, wired or heterogeneous) can benefit in terms of improved resilience (in addition to other performance benefits such as throughput) in its design. Case studies in this effort are designed to help transition the theoretical principles developed into practical algorithms. The research team includes an industry member which will aid in transitioning our research ideas from theory to practice. The team will disseminate its findings through traditional scholarly venues, through the web and to the local community at each partner institution.

该奖项根据2009年美国复苏和再投资法案（公法111-5）提供资助。该项目从网络编码的角度确定了网络保密的基本限制，然后应用该理论来改善点对点的安全保障。对等网络和无线网络。随着网络编码作为有线和无线网络的重要策略而受到重视，该项目确定了使用网络编码的优点和缺点。随后，我们开发了一种设计方法，在充分利用优势的同时仔细弥补漏洞。该项目分析了外部和内部攻击下的网络。具体来说，开发编码机制是为了对抗外部窃听者。此外，密码学和信息论工具的组合用于对抗网络上的内部修改攻击。然后将结果用于两个案例研究：对无线网状网络的窃听者攻击和对 P2P 内容分发系统的污染攻击。安全网络编码系统一旦被充分理解，就会极大地影响网络的设计和部署方式。几乎所有网络设置（无线、有线或异构）都可以在其设计中提高弹性（除了吞吐量等其他性能优势之外）。这项工作的案例研究旨在帮助将理论原理转化为实际算法。研究团队包括一名行业成员，这将有助于将我们的研究理念从理论转化为实践。该团队将通过传统学术场所、网络以及每个合作机构的当地社区传播其研究结果。
