A significant amount of sensitive data communicated over wireless media makes wireless communication security an issue of paramount importance. The standard implemented solution to security over wireless networks is based on a modular approach in which transmission and encryption are carried out separately. State-of-the-art encryption algorithms are thus agnostic to the characteristics of the underlying network, but this separation approach is increasingly hard to justify as fast and reliable communications over wireless networks require more effective security architectures.Several theoretical insights have been obtained from information theory in the past few years that suggest that fundamentally secure transmission in wireless interference networks is possible by jointly designing for reliability and security at the outset. This project takes a distinctive approach to accelerate the deployment of information-theoretically secure design of wireless networks by analyzing models with realistic assumptions, developing practical coding schemes and validating with a wireless test-bed. The project investigates two intertwined research tasks: (i) overcoming modeling assumptions, by providing security guarantees irrespective of adversaries' channels, modeling and countering adversaries that can manipulate channel conditions to their advantage, and removing idealized assumptions in implementation; (ii) providing explicit channel code designs that ensure strong secrecy and developing secure codes for multi-terminal wireless networks.Additional activities related to the project include : (i) outreach to the computational security community towards integration of information-theoretic and computational security principles; (ii) dissemination of research results in various forms; (iii) a research exchange program between Georgia Tech and Penn State; (iv) a jointly taught graduate level course by the PIs that incorporates the research results of this project; and (v) recruitment of and mentorship for women in engineering and science. The research conducted in this project will facilitate the implementation of information-theoretic security principles on wireless systems and lead to novel cost-effective security techniques at the physical-layer.

通过无线媒体传输的大量敏感数据使得无线通信安全成为一个至关重要的问题。标准实现的无线网络安全解决方案基于模块化方法，其中传输和加密是分开执行的。因此，最先进的加密算法与底层网络的特征无关，但这种分离方法越来越难以证明其合理性，因为无线网络上的快速可靠的通信需要更有效的安全架构。过去几年的信息理论表明，通过从一开始就可靠性和安全性进行联合设计，无线干扰网络中的根本安全传输是可能的。该项目采用独特的方法，通过分析具有现实假设的模型、开发实用的编码方案并使用无线测试台进行验证，来加速无线网络信息理论上安全设计的部署。该项目调查了两个相互交织的研究任务：（i）克服建模假设，无论对手的通道如何，都提供安全保证，建模并对抗可以操纵通道条件以达到其优势的对手，并消除实施中的理想化假设； (ii) 提供明确的信道代码设计，确保高度保密，并为多终端无线网络开发安全代码。与该项目相关的其他活动包括：(i) 向计算安全界拓展，以整合信息理论和计算安全原则; (ii) 以各种形式传播研究成果； (iii) 佐治亚理工学院和宾夕法尼亚州立大学之间的研究交流计划； (iv) 由 PI 联合教授的研究生课程，其中包含本项目的研究成果； (v) 工程和科学领域女性的招聘和指导。该项目中进行的研究将促进信息论安全原则在无线系统上的实施，并在物理层产生新颖的、经济有效的安全技术。
