TrustSAS：一种3.5 GHz CBRS频段的可信频谱接入系统
TrustSAS: A Trustworthy Spectrum Access System for the 3.5 GHz CBRS Band
摘要：
作为满足不断增长的频谱需求的持续努力的一部分，联邦通信委员会（FCC）最近开放了3.5 GHz频段中的150 MHz用于共享无线宽带使用。该频段的接入和运营，也就是公民宽带无线电服务（CBRS），将由动态频谱接入系统（SAS）管理，以实现二级用户（SU）和现任用户之间的无缝频谱共享。尽管有这些好处，但由FCC设定的SAS设计要求给SU带来了隐私风险，这仅仅是因为SU需要共享敏感的操作信息（例如，位置、身份、频谱使用），以便能够了解其附近的频谱可用性。在本文中，我们提出了TrustSAS，这是一个值得信赖的SAS框架，它以创新的方式将最先进的加密技术与区块链技术相结合，以解决这些隐私问题，同时符合FCC的监管设计要求。我们分析了我们的框架的安全性，并通过分析，仿真和实验来评估其性能。我们表明，TrustSAS可以提供合理的开销高的安全保证，使其成为一个理想的解决方案，解决SU的隐私问题，在一个可操作的SAS环境。
英文摘要：
As part of its ongoing efforts to meet the increased spectrum demand, the Federal Communications Commission (FCC) has recently opened up 150 MHz in the 3.5 GHz band for shared wireless broadband use. Access and operations in this band, aka Citizens Broadband Radio Service (CBRS), will be managed by a dynamic spectrum access system (SAS) to enable seamless spectrum sharing between secondary users (SUs) and incumbent users. Despite its benefits, SAS's design requirements, as set by FCC, present privacy risks to SUs, merely because SUs are required to share sensitive operational information (e.g., location, identity, spectrum usage) with SAS to be able to learn about spectrum availability in their vicinity. In this paper, we propose TrustSAS , a trustworthy framework for SAS that synergizes state-of-the-art cryptographic techniques with blockchain technology in an innovative way to address these privacy issues while complying with FCC's regulatory design requirements. We analyze the security of our framework and evaluate its performance through analysis, simulation and experimentation. We show that TrustSAS can offer high security guarantees with reasonable overhead, making it an ideal solution for addressing SUs' privacy issues in an operational SAS environment.
