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

高效和安全地使用共享频谱对于支持新兴的5G无线应用的需求至关重要，这些应用在整个社会都有潜在的好处。该项目正在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，例如最近敲定的3.5 GHz公民宽带无线电服务(CBRS)频段的规则。这些新的模式将导致提供无线服务的新的市场结构。然而，这种扩展的灵活性也可能导致无线系统的安全漏洞增加。这两个问题内在地联系在一起。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善这一点的意愿。此外，在许多频谱共享模式中，可能存在不同类型的交互公司，例如服务提供商、数据库运营商等。这些公司之间的经济和技术交互将决定最终用户获得的安全级别。一般来说，这种相互作用并没有得到很好的理解。该项目的目标是加深对新兴频谱共享范例中安全和市场之间的相互作用的理解，包括确定在市场环境中部署安全机制的成本和激励因素。因此，该项目有望减少与共享频谱中的安全问题相关的经济不确定性。该研究正在以以前从未在共享频谱背景下探索的方式，将无线网络、网络安全和网络经济学的想法结合在一起。正在解决的具体问题领域包括(1)研究无线服务提供商应该如何定价和提供“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法如何影响提供商的竞争和安全投资激励；(3)评估空间干扰的影响及其连锁反应的经济和安全影响。理论见解与评估计划相辅相成，该计划利用模拟和可用的数据集来确保其稳健性和适用性。其他正在寻求的更广泛的影响包括：(1)吸引本科生和代表性不足的学生；(2)开发无线安全实验室；以及(3)在领先的会议上组织关于项目主题的研讨会和辅导会议，以告知来自政府、行业和学术界的利益相关者，并促进互动。该奖项反映了NSF的法定使命，并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，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.
