Wireless connectivity has become the primary way most users access cyberspace. The wide use of the internet on wireless and mobile devices is further encouraged with new services that simultaneously engage and connect a large number of users. As a result, the society at large is quickly getting comfortable with the idea of conducting everyday lives on mobile devices most of which require communicating sensitive and confidential information over the wireless medium. Consequently, secure access to cyberspace necessitates wireless security. Wireless, being an open medium, is more prone to malicious cyber acts as compared to wired connectivity. On the other hand, this medium also presents unique opportunities to provide security guarantees through the interaction of nodes and advanced physical layer techniques. In particular, information theoretic security emerges with design insights that provide guaranteed security against computationally unlimited adversaries. In order to do so, information theory assumes a network of altruistic nodes and looks for fundamental performance limits which usually come with complex interaction and coordination requirements. The premise of this project is that this idealistic set-up can be successfully transformed into a practical one by amalgamating information theory with the theory of incentives in order to provide secure wireless cyber access.Specific research topics being addressed include the development of: (1) mechanisms to incentivize non-altruistic cognitive nodes to participate in information theoretic security protocols; (2) incentive mechanisms for scenarios where all nodes have equal access to spectrum and need confidentiality, even from each other; (3) techniques for providing security to groups of cooperative nodes and the associated trust issues; (4) incentive mechanisms for combating active attacks; (5) strategies for combating colluding adversaries; and (6) mechanisms to ensure that nodes have the incentive to adopt a given security protocol.Broader impacts of this work include: (1) providing secure access to cyberspace via the wireless medium; (2) new design insights for practical security protocols; and (3) amalgamating information theory and game theory via incentive mechanisms. Educational broader impacts include: (1) dissemination of research results in the form of tutorials and short courses; (2) enhancing graduate-student research experiences via a three-university research exchange program; (3) incorporating the research results into graduate and undergraduate communications courses; and (4) recruitment of and mentorship for women in engineering and science.

无线连接已成为大多数用户访问网络空间的主要方式。通过同时吸引和连接大量用户的新服务，进一步鼓励在无线和移动的设备上广泛使用互联网。结果，整个社会很快适应了在移动的设备上进行日常生活的想法，其中大多数设备需要通过无线介质传送敏感和机密信息。因此，安全访问网络空间需要无线安全。与有线连接相比，无线作为一种开放介质更容易受到恶意网络行为的影响。另一方面，这种介质也提供了独特的机会，通过节点和先进的物理层技术的相互作用提供安全保证。特别是，信息理论的安全性出现了设计的见解，提供保证的安全性，对计算上无限的对手。为了做到这一点，信息理论假设了一个利他节点网络，并寻找基本的性能限制，这些限制通常伴随着复杂的交互和协调要求。本课题的前提是通过将信息论与激励理论相结合，将这种理想化的网络结构成功地转化为实际的网络结构，以提供安全的无线网络接入，具体研究内容包括：（1）激励非利他认知节点参与信息论安全协议的机制;（2）用于所有节点具有对频谱的平等访问并且需要保密性（甚至彼此保密）的场景的激励机制;（3）用于向协作节点组提供安全性的技术以及相关联的信任问题;（4）用于对抗主动攻击的激励机制;（5）用于对抗勾结对手的策略;以及（6）确保节点有动机采用给定安全协议的机制。这项工作的更广泛影响包括：（1）通过无线介质提供对网络空间的安全访问;（2）为实用安全协议提供新的设计见解;（3）通过激励机制融合信息论和博弈论。教育方面的广泛影响包括：（1）以辅导和短期课程的形式传播研究成果;（2）通过三所大学的研究交流方案加强研究生的研究经验;（3）将研究成果纳入研究生和本科生的交流课程;（4）招聘和指导工程和科学领域的妇女。
