SpecEES: DoS Resilience, Secrecy, and Throughput in Massive MIMO

该项目的目标是为在下一代无线网络中实现拒绝服务(DoS)-弹性、保密性和高吞吐量-开发基础，在下一代无线网络中，基站或接入点(AP)将其天线和计算资源扩展到大规模多输入/多输出(MIMO)。该项目考虑了一个实际但强大的对手，它既发起了主动攻击，试图通过污染AP的信道状态信息(CSI)测量来崩溃网络吞吐量，也发起了被动攻击，试图通过潜在的分布式和游牧式窃听者拦截通信。第一个项目推力目标，以零启动成本检测和防御飞行员污染攻击，即不需要在没有攻击的情况下事先测量条件。第二个项目推力实验探索了现实世界因素下的被动窃听，例如大量但有限的天线和离散而有限的调制和编码方案(MCS)集。随着MCS饱和漏洞的发现，该项目将研究旨在克服该漏洞并挫败对手的功率控制。在上行链路上，第三个项目推力开发天线索引编码，作为在大规模MIMO阵列的子集上进行目标接收的手段。一个关键的结果将是得出保密率以及对这一新机制的实验评估。所有三个项目的推进都将包括一项广泛的实验研究，使用莱斯大规模MIMO平台和空中测量。由于必须投入计算和通信资源来实现上述对抗机制，该项目将对实现高频谱效率和安全性的权衡产生经验上的理解。拟议的研究议程将使新的无线安全防御成为可能，并将对大规模MIMO等下一代通信系统的安全提供深入的理解。该项目将对设计空间产生新的理解，从传统的吞吐量优化到通过设计联合实现安全功能和提供安全。这个项目将产生对基于CSI作为共享秘密的设计的安全能力和限制的新理解。该项目将影响标准机构，因为它将暴露现有安全机制的基本限制，并将展示对标准的增强如何产生显著改进的安全能力。该项目将通过展示结果以及研究人员广泛的合作行业网络来影响行业。最后，该项目包括一种跨学科的方法，团队包括来自代表性不足群体的多名博士生。这一奖项反映了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。

The project's objective is to develop the foundations for realizing denial of service (DoS)-resilience, secrecy, and high throughput in next-generation wireless networks in which base stations or access points (APs) scale their antenna and computing resources to massive multiple-input/multiple-output (massive MIMO). This project considers a practical yet strong adversary that launches both active attacks, attempting to collapse network throughput by polluting AP measurement of Channel State Information (CSI), as well as passive attacks, that attempt to intercept communication via potentially distributed and nomadic eavesdroppers. The first project thrust targets to detect and defend against pilot contamination attacks with zero startup cost, i.e., without requiring prior measurements of conditions without an attack. The second project thrust experimentally explores passive eavesdropping under realworld factors such as a large but finite number of antennas and a discrete and limited set of modulation and coding schemes (MCS). With a discovery of MCS saturation vulnerability, the project will study power control designed to overcome this vulnerability and thwart the adversary. On the uplink, the third project thrust develops antenna index coding as means to target reception on a subset of the massive MIMO array. A key outcome will be both derivation of the secrecy rate as well as experimental evaluation of this new mechanism. All three project thrusts will include an extensive experimental study using the Rice massive MIMO platform and over-the-air measurements. As computing and communication resources must be devoted to realizing the aforementioned counter mechanisms, this project will yield empirical understanding of the tradeoffs in realizing both high spectral efficiency and security.The proposed research agenda will enable new wireless security defenses and will provide an in-depth understanding of securing next generation communication systems such as massive MIMO. This project will yield new understanding of the design space that spans from traditional throughput optimization to jointly realizing security features and providing security by design. This project will yield new understanding of the security capabilities and limits of designs based on CSI as a shared secret. This project will impact standards bodies as it will expose fundamental limits of existing security mechanisms and will show how enhancements to standards can yield dramatically improved security capabilities. This project will impact industry through demonstration of results coupled with the researchers' extensive collaborative industry network. Finally, the project includes an inter-disciplinary methodology and the team includes multiple Ph.D. students from under-represented groups.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.
