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.

动态频谱接入 (DSA) 是一种频谱共享方法，允许二级用户 (SU) 有机会接入已授权给现有用户 (IU) 的未充分利用的频段。它有可能显着提高频谱利用效率并显着提高无线通信容量。然而，DSA 引发了许多新的操作隐私问题，因为现有的设计要求 IU 和 SU 向不受信任的第三方提供敏感的操作数据。例如，许多政府 IU 的运营数据都是保密的。 SU 的运营数据也可能是其运营商的商业秘密。虽然一些现有的研究已经考虑了隐私保护，但这些工作未能考虑其方案对 DSA 系统的效率和容量的重大负面影响。因此，在频谱效率、容量和运营隐私问题得到共同解决之前，监管机构和潜在的 SU/IU 运营商往往不愿意采用 DSA。该项目的目标是通过对各种可能的 DSA 系统设计的效率、容量和隐私进行联合研究来解决上述挑战。该项目将提供解决 DSA 系统操作隐私问题的解决方案，同时不会牺牲频谱分配效率和系统容量。该项目可以极大地促进DSA技术的采用，从而提高整个国家无线宽带网络的容量。对代表性不足群体的支持也纳入了该项目的工作中。该项目有两个主旨。主旨 1 研究集中式 DSA 设计中高效且安全的频谱分配，而主旨 2 研究分布式 DSA 的相同问题。 对于集中式 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，每种类型的中心化设计中的隐私和安全威胁都将被单独深入研究。 新方案的设计将针对每种类型的集中式 DSA 设计来应对这些威胁，并同时考虑频谱分配效率和系统容量。对于分布式DSA，用户之间交换的信息可能会无意中向其他（不受信任的）用户泄露这些用户的敏感信息，或者使系统面临某些用户在信息交换过程中撒谎的作弊威胁。该项目将探索解决这些问题的方法，并重点确保所提出的解决方案不会降低分布式系统设计的效率，同时保护信息交换的隐私和可信性。该奖项反映了 NSF 的法定使命，并被认为是值得的通过使用基金会的智力优势和更广泛的影响审查标准进行评估来获得支持。
