This project aims to advance our fundamental understanding of secrecy over arbitrary wireless networks. Over the last decade we have significantly deepened our fundamental understanding on how to send information over wireless networks, while our understanding on how to securely send this information has not reached the same depth as yet. This project aims to develop a unifying theory that enhances wireless secrecy by exploiting wireless properties such as: the existence of feedback (today part of all wireless standards); the possibility of selecting and using multiple network communication paths; the smart use of wireless jamming and the wireless channel variability and unpredictability. We enable this by "building on erasures:" through appropriate coding and smart wireless jamming, we convert (Gaussian) wireless networks to erasure networks. We then develop protocols that use interaction and feedback to enable provable security against active and passive adversaries, even if they are computationally unbounded. The project also promotes the training of research engineers: we will integrate the research into the curriculum via the creation of novel coursework combining the underlying concepts in wireless communication, network coding/protocols, and information theory. The research in this project, if successful, will contribute to the fundamental sciences of information theoretic network security and secure network coding. Given our increasing dependence on wireless devices as a portal for socio-economic activities, wireless security will have broad implications in mobile commerce.

该项目旨在推进我们对任意无线网络上的保密性的基本理解。在过去的十年里，我们已经大大加深了对如何通过无线网络发送信息的基本理解，而我们对如何安全地发送这些信息的理解还没有达到同样的深度。该项目旨在开发一种统一的理论，通过利用无线特性来增强无线保密性，例如：反馈的存在（今天所有无线标准的一部分）;选择和使用多个网络通信路径的可能性;无线干扰的智能使用以及无线信道的可变性和不可预测性。我们通过“建立在擦除之上“来实现这一点：通过适当的编码和智能无线干扰，我们将（高斯）无线网络转换为擦除网络。然后，我们开发的协议，使用交互和反馈，使可证明的安全性对主动和被动的对手，即使他们是计算无界的。 该项目还促进了研究工程师的培训：我们将通过创建新颖的课程，结合无线通信，网络编码/协议和信息理论的基本概念，将研究融入课程。本课题的研究如果成功，将对信息论网络安全和安全网络编码的基础科学做出贡献。鉴于我们越来越依赖无线设备作为社会经济活动的门户，无线安全将在移动的商务中产生广泛的影响。
