TWC SBE: Medium: Collaborative: Incentive Compatible Wireless Security

无线连接已成为大多数用户访问网络空间的主要方式。通过同时接触和连接大量用户的新服务，进一步鼓励在无线和移动设备上广泛使用互联网。因此，整个社会很快就习惯了在移动设备上进行日常生活的想法，这些设备中的大多数都需要通过无线介质来通信敏感和机密信息。因此，安全访问网络空间需要无线安全。无线作为一种开放的媒介，与有线连接相比，更容易发生恶意网络行为。另一方面，这种媒介也提供了独特的机会，通过节点和高级物理层技术的交互来提供安全保证。特别是，信息论安全伴随着设计洞察力的出现，这些设计洞察力提供了针对计算无限的攻击者的有保证的安全。为了做到这一点，信息论假设了一个利他主义节点的网络，并寻找通常伴随着复杂的交互和协调要求的基本性能极限。本项目的前提是通过将信息论和激励理论相结合，成功地将这种理想化的设置转变为实用的设置，从而提供安全的无线网络接入。具体的研究课题包括：(1)激励非利他认知节点参与信息论安全协议的机制；(2)针对所有节点都具有平等的频谱访问和需要保密的场景的激励机制；(3)为协作节点组提供安全的技术以及相关的信任问题；(4)对抗主动攻击的激励机制；这项工作的广泛影响包括：(1)通过无线媒介提供对网络空间的安全访问；(2)为实用的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。更广泛的教育影响包括：(1)以教程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计划加强研究生之间的研究经验；(3)将研究成果纳入研究生和本科生的沟通课程；以及(4)招聘和指导工程和科学专业的女性。

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.
