Physical Layer Security: Error Control Coding for Information Theoretic Security in Wireless and Beyond

这项研究。该方案的研究主题是：1)窃听信道的基本原理：用于可靠性和安全性的差错控制码；2)机会无线物理层安全；3)高可靠和安全的分布式数据存储。在所有领域，重点不仅在理论上，而且在实践算法上，以实现信息论承诺的非常高的安全和可靠性水平。PI和协作：本提案中约一半的工作将与欧洲的合作者一起完成，该合作伙伴连接到位于法国梅茨的佐治亚理工学院(GTL)园区，PI曾在那里担任研究主任，现任副主任。2006年3月，国际和平研究所及其同事与法国国家科学研究中心(CNRS)合作，建立了一个联合研究中心，致力于安全网络和先进材料方面的国际合作，这是法国首个此类研究中心。这个中心接待了来自四个机构的15个人和10个项目。该提案的无线部分将与波尔图大学(J.Barros)和剑桥大学(M.Rodrigues)的同事合作完成。我们项目的国际部分创造了机遇和挑战。例如，今天招收和培养研究生的情况是：i)申请美国大学的学生减少，特别是来自中国和印度的学生；ii)美国学生缺乏在美国以外获得有意义的工程教育和研究经验的人。我们相信，这个项目与法国的GTL园区相结合，可以应对其中一些挑战，并帮助培养具有更全球化视野的未来工程师、教育工作者和研究人员。该项目的更广泛影响有两个方面：i)通过新的无线安全概念商业化的途径建立全球联系；以及ii)跨国界培养研究生的新模式。学生和教职员工将参与新的和持久的国际研究和教育活动。这些学生将有更多的全球视野，有机会与欧洲学生和教职员工进行长期互动，该项目将有助于(为公司、大学和政府机构)寻找具有全球视野的杰出人才。这个模型解决了美国和国外学生和教师不断变化的环境和需求。从理论和实践的角度来看，物理层通信的新方法具有智力上的优势。高度安全可靠的物理层的概念有可能显著改变人们对物理层的看法。这项工作中的差错控制码将具有可靠性和安全性的双重作用，为这个已经深入研究了60多年的课题增添了一个新的维度。我们相信，这里提出的研究将导致人们对经典通信系统的认知和使用方式的改变，并将是更高性能的物理层通信系统的下一个自然步骤。

The research. The research topics in this proposal are: 1) Fundamentals for the wiretap channel:error control codes for reliability and security, 2) Opportunistic wireless physical-layer security, 3) Highlyreliable and secure distributed data storage. In all areas the focus is not only on theory but on practicalalgorithms to achieve the very high levels of security and reliability promised by information theory.The PI and collaborations: About half of the work in this proposal will be done with collaboratorsin Europe connected to the Georgia Tech Lorraine (GTL) campus in Metz, France where the PI wasformerly Director of Research and currently Deputy Director. In March 2006, the PI and his colleagues, inpartnership with the French Centre National de Recherche Scientifique (CNRS), established a joint researchcenter dedicated to international collaborations in secure networks and advanced materials, the first suchcenter of its kind in France. This center hosts fifteen people and ten projects from four institutions. Thewireless portion of this proposal will be done in collaboration with colleagues at the University of Porto (J.Barros) and Cambridge University (M. Rodrigues). The international component of our project createsopportunities and challenges. For example, the landscape for recruiting and educating graduate studentstoday is characterized by i) decreases in the students applying to US universities, particularly from Chinaand India, and ii) a lack of US students getting meaningful engineering educational and research experienceoutside the US. We believe this project, coupled with the GTL campus in France, can address some ofthese challenges and help create future engineers, educators and researchers with a more global perspective.The broader impact of this project has two dimensions: i) global connections with a pathway tocommercialization of new wireless security concepts; and ii) new models for training graduate studentsacross national boundaries. The students and faculty would participate in new and long-lasting internationalresearch and educational activities. These students will have a much more global perspective, have theopportunity to interact on a long-term basis with European students and faculty, and the project wouldserve to identify (for companies, universities and government agencies) outstanding people with a globalperspective. This model addresses the changing landscape and needs of student and faculty in the US andabroad.The intellectual merit is in new approaches to physical layer communications, from both theoreticaland practical perspectives. The notion of a highly secure and reliable physical layer has the potential tosignificantly change how people think of the physical layer. The error control codes in this work will havethe dual roles of reliability and security, adding a new dimension to a subject that has been studiedextensively for more than 60 years. We believe the research presented here will result in changes in howclassical communication systems are perceived and used, and is the next natural step in higherperformance, physical layer communication systems.
