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.

该奖项是根据2009年的《美国复苏与重新投资法》（公共法第111-5号）资助的。本项目从网络编码的角度确定网络保密的基本限制，然后应用该理论来提高对等点对点和无线网络的安全保证。由于网络编码成为有线和无线网络的重要策略，因此该项目可以确定使用网络编码的优势和漏洞。随后，努力开发了一种设计方法，该方法可以利用优势，同时仔细补偿漏洞。该项目分析了局外人和内部攻击下的网络。具体而言，开发了编码机制来对抗外部窃听器。此外，使用加密和信息理论工具的组合用于对抗网络上的内部修改攻击。然后在两个案例研究中使用结果：对无线网络网络的窃听攻击以及对P2P内容分布系统的污染攻击。安全网络编码的系统一旦得到充分理解，就会极大地影响网络的设计和部署方式。几乎每个网络设置（无线，有线或异质）都可以在其设计中受益于提高的弹性（除其他性能益处）方面。这项工作中的案例研究旨在帮助过渡到实用算法中的理论原则。研究团队包括一个行业成员，将有助于将我们的研究思想从理论转变为实践。该团队将通过传统学术场所，网络和每个合作伙伴机构的当地社区传播其发现。
