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.

通过无线媒体传达的大量敏感数据使无线通信安全是至关重要的问题。通过无线网络实施的标准安全解决方案是基于模块化方法，在该方法中，分别进行传输和加密。因此，最新的加密算法对基础网络的特征不可知，但是这种分离方法越来越难以证明与无线网络的快速可靠的通信相当合理，需要更有效的安全架构。在过去几年中，从信息理论中获得了一些理论上的见解，这表明通过在一开始就可以共同设计可靠性和安全性，可以从无线干扰网络中提供根本性的安全传输。该项目采用一种独特的方法来通过分析具有现实假设，开发实用的编码方案并使用无线测试床验证的模型来加速理论上的无线网络设计。该项目调查了两项相互交织的研究任务：（i）通过提供安全保证来克服建模假设，无论对手的渠道，对对手的建模和反击都可以使渠道条件以其优势操纵其优势，并消除实施方面的理想化假设； （ii）提供明确的频道代码设计，以确保强大的保密性并为多末端无线网络开发安全的代码。与该项目相关的其他活动包括：（i）向计算安全界的宣传信息理论和计算安全原则的整合； （ii）以各种形式传播研究结果； （iii）佐治亚理工学院与宾夕法尼亚州立大学之间的研究交流计划； （iv）PIS结合了该项目的研究结果； （v）工程和科学妇女的招聘和指导。该项目进行的研究将促进无线系统上信息理论安全原则的实施，并导致物理层的新颖具有成本效益的安全技术。
