Dynamic spectrum access (DSA) is a spectrum sharing method that allows secondary users (SUs) to opportunistically access under-utilized spectrum bands that were licensed to incumbent users (IUs). It has the potential to dramatically improve the spectrum utilization efficiency and significantly boost the capacity of wireless communications. However, DSA gives rise to many new operational privacy issues because the existing designs require IUs and SUs to provide sensitive operational data to untrusted third parties. As an example, the operational data for many government IUs is classified. The SUs' operational data may also be a commercial secret for their operators. While some existing research has considered privacy protections, these works fail to consider the significant negative impact of their schemes on the efficiency and capacity of DSA systems. Thus, regulators and potential SU/IU operators often are unwilling to adopt DSA before the spectrum efficiency, capacity and operation privacy issues can be jointly addressed. The goal of this project is to solve the above challenges by providing a joint study of efficiency, capacity and privacy for a comprehensive range of possible DSA system designs. This project will provide solutions for addressing operational privacy concerns of DSA systems without sacrificing spectrum allocation efficiency and system capacity. This project can greatly promote the adoption of DSA technologies and hence enhance the capacity of the entire nation's wireless broadband networks. Supporting of underrepresented groups is also integrated in this project effort. This project has two thrusts. Thrust 1 studies the efficient and secure spectrum allocation in centralized DSA designs, while thrust 2 studies the same issue for distributed DSA. For centralized DSA, both the central entity and end users are considered to be potentially compromised. With these assumptions, the privacy and security threats in each types of centralized designs will be thoroughly studied individually. New schemes will be designed to address these threats for each type of centralized DSA designs with joint considerations on both spectrum allocation efficiency and system capacity. For distributed DSA, the information exchanged among the users may inadvertently reveal sensitive information of these users to other (untrusted) users or expose the system to threats of cheating where some users may lie during information exchange. This project will explore approaches to solve these issues and focus on making sure that the proposed solutions do not reduce the efficiency of the distributed system design while protecting the privacy and trustworthiness of the information exchange.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

动态频谱访问（DSA）是一种频谱共享方法，它允许二级用户（SUS）访问获得许可的现有用户（IUS）的机会不足的频谱频段。它有可能显着提高频谱利用效率并显着提高无线通信的能力。但是，DSA引起了许多新的操作隐私问题，因为现有的设计需要IUS和SUS向不受信任的第三方提供敏感的操作数据。例如，许多政府IUS的操作数据被分类。 SUS的操作数据也可能是其运营商的商业秘密。尽管一些现有的研究考虑了隐私保护，但这些作品未能考虑其计划对DSA系统效率和能力的重大负面影响。因此，在可以共同解决频谱效率，能力和操作隐私问题之前，监管机构和潜在的SU/IU运营商通常不愿意采用DSA。该项目的目的是通过为全面的DSA系统设计提供效率，能力和隐私的联合研究来解决上述挑战。该项目将为解决DSA系统的操作隐私问题提供解决方案，而无需牺牲频谱分配效率和系统容量。该项目可以大大促进DSA技术的采用，从而提高整个国家无线宽带网络的能力。支持代表性不足的群体的支持也集成在此项目工作中。该项目有两个推力。推力1研究集中式DSA设计中的有效且安全的频谱分配，而推力2研究了分布式DSA的相同问题。 对于集中的DSA，中央实体和最终用户都被认为可能受到损害。 有了这些假设，将对每种类型的集中设计中的隐私和安全威胁进行单独研究。 新方案将旨在解决每种类型的集中DSA设计的威胁，并在频谱分配效率和系统容量上进行联合考虑。对于分布式DSA，用户之间交换的信息可能会无意间向其他（不受信任的）用户透露这些用户的敏感信息，或者将系统暴露于某些用户在信息交换过程中可能撒谎的作弊威胁。该项目将探索解决这些问题的方法，并专注于确保所提出的解决方案不会在保护信息交换的隐私和可信度的同时降低分布式系统设计的效率。该奖项反映了NSF的法定任务，并认为通过使用基金会的知识智能和更广泛的影响来审查Criteria的评估。
