CNS Core: Small: Collaborative Research: The Interplay of Markets and Security in 5G Shared Spectrum Services

高效、安全地使用共享频谱对于支持新兴5G无线应用的需求至关重要，5G无线应用对整个社会都有潜在的好处。该项目通过考虑使用更灵活的频谱接入范例的5G无线网络中相互交织的经济和安全问题来解决这些问题，例如最近确定的3.5 GHz公民宽带无线电服务（CBRS）频段规则。这些新范例将为提供无线服务带来新的市场结构。然而，这种扩展的灵活性也可能导致无线系统安全漏洞的增加。这两个问题本质上是相互关联的。例如，新兴市场结构可能会影响公司向客户提供的安全性，以及公司开发和部署技术以改进安全性的意愿。此外，在许多频谱共享范例中，可能存在不同类型的交互企业，如服务提供商、数据库运营商等。这些公司之间的经济和技术相互作用将决定最终用户的安全水平。一般来说，这种相互作用还没有得到很好的理解。该项目的目标是更深入地了解新兴频谱共享范式中安全与市场之间的相互作用，包括描述在市场环境中部署安全机制的成本和动机。因此，该项目有望减少与共享频段安全问题相关的经济不确定性。这项研究结合了无线网络、网络安全和网络经济学的思想，这是以前在共享频谱的背景下从未探索过的。具体问题包括：(1)研究无线服务供应商应如何定价和提供“安全即服务”；(2)了解多个无线服务提供商的市场互动，以及不同的频谱共享方式如何影响提供商的竞争和安全投资激励；(3)评价空间干扰的影响及其对经济和安全的连锁效应。理论见解与利用模拟和可用数据集的评估计划相辅相成，以确保其鲁棒性和适用性。其他更广泛的影响包括：(1)吸引本科生和代表性不足的学生；(2)建立无线安全实验室；(3)在主要会议上组织关于项目主题的研讨会和辅导课，向政府、行业和学术界的利益相关者提供信息，促进互动。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Efficient and secure use of shared spectrum is critical to support the demands from emerging 5G wireless applications that have potential benefits across society. This project is addressing these by considering intertwined economic and security issues in 5G wireless networks that use more flexible spectrum access paradigms, such as the recently finalized rules for the 3.5 GHz Citizens Broadband Radio Service (CBRS) band. These new paradigms will result in new market structures for providing wireless services. However, this expanded flexibility can also lead to an increase in the security vulnerabilities of wireless systems. These two issues are inherently coupled. For example, the emerging market structures can impact the security a firm can offer to its customers and the firm's willingness to develop and deploy technology to improve on this. Moreover, in many spectrum sharing paradigms there may be different types of interacting firms such as service providers, database operators, etc. The economic and technological interactions among these firms will dictate the resulting security level given to end-users. Such interactions are not well understood in general. The goal of this project is to develop a deeper understanding of the interactions between security and markets in emerging spectrum sharing paradigms, including characterizing the cost and incentives of deploying security mechanisms in market environments. Thus, the project is expected to reduce economic uncertainties tied to security issues in shared spectrum bands.The research is combining ideas from wireless networking, cyber-security and network economics in ways that have not been previously explored in the context of shared spectrum. Specific problems areas being addressed include (1) studying how wireless service providers should price and provision "security-as-a-service"; (2) understanding the market interactions of multiple wireless service providers and how different spectrum sharing approaches impact the competition and security investment incentives of the providers; (3) evaluating the impact of spatial interferences and their knock-on economic and security effects. The theoretical insights are complemented with an evaluation plan that leverages simulations and available data sets to ensure their robustness and applicability. Other broader impacts being pursued include: (1) engaging undergraduate and under-represented students; (2) developing wireless security labs; and (3) organizing workshop and tutorial sessions on the project's topic at leading conferences, to inform stakeholders from government, industry, and academia and foster interactions.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.
