The development of radio technologies that support efficient and reliable spectrum sharing is an enabler for utilizing the spectrum being made available through the National Broadband Plan. Software defined radios represent a promising technology that supports spectrum sharing as evidenced by the large amount of algorithms and protocols that allow for cognitive radio networks (CRNs) to be deployed. Unfortunately, the economic promise of dynamic spectrum access is easily undermined if cognitive radio users act dishonestly or maliciously, thereby subverting protocols that are founded on the cooperation of users. It is therefore important that mechanisms are developed that ensure the trustworthy operation of CRNs in the presence of potentially malicious or malfunctioning wireless nodes. The objective behind the project's research activities is to develop technological solutions that ensure that cognitive radios operate in trustworthy manner in spite of potential security threats. As a result of this research effort, it is possible for radio spectrum to be more reliably utilized, thereby ensuring that the economic opportunities associated with the radio spectrum are fairly utilized by everyone. The educational impact of the work comes from its multi-disciplinary foundation, broadening student views of wireless system design, and guiding the next generation of wireless engineer to include security and reliability in the design process. Wireless technologies are an enabler for economic growth in the United States, and cognitive radio networks are an emerging form of wireless system that make spectrum access more available to the broader population. Unfortunately, cognitive radio systems are susceptible to threats that undermine the correct operation of their algorithms and protocols, and thus solutions that support the secure operation of cognitive radio networks are needed. This project ensures the trustworthy operation of cognitive radio networks by: 1) developing algorithms that ensure the correct operation of spectrum sensing procedures upon which spectrum access protocols rely; 2) developing traffic monitoring tools that identify improper communication activity by cognitive radio devices; and 3) developing new forms of interference-resistant communications that ensure that cognitive radio communication continues reliably in the face of interference. The research effort is inter-disciplinary, pulling from statistical tools to network traffic analysis to communications theory to support the secure operation of cognitive radio networks. The algorithms and protocols developed in this project are complemented by a systems prototyping and experimentation effort aimed at guaranteeing that the technologies developed are suitable for deployment in real wireless systems.

支持有效且可靠的频谱共享的无线电技术的开发是利用通过国家宽带计划提供的频谱的推动力。软件定义的无线电代表了一种有前途的技术，该技术支持频谱共享，这是由大量算法和协议所证明的，这些算法和协议允许部署认知无线网络（CRN）。不幸的是，如果认知无线电用户不诚实或恶意行事，则很容易破坏动态频谱访问的经济承诺，从而颠覆建立在用户合作的方案中。因此，重要的是要开发机制，以确保在存在潜在的恶意或故障无线节点的情况下CRN的可信赖操作。该项目研究活动背后的目的是开发技术解决方案，以确保尽管存在潜在的安全威胁，但认知无线电以可信赖的方式运作。由于这项研究的工作，可以更可靠地利用无线电频谱，从而确保每个人都相当利用与无线电频谱相关的经济机会。这项工作的教育影响来自其多学科基础，扩大学生对无线系统设计的看法，并指导下一代无线工程师在设计过程中包括安全性和可靠性。 无线技术是美国经济增长的推动力，而认知无线网络是无线系统的新兴形式，它使频谱访问更广泛地为广泛的人群使用。不幸的是，认知无线电系统容易受到破坏其算法和协议正确操作的威胁，因此需要支持支持认知无线网络安全操作的解决方案。该项目确保了认知无线网络的值得信赖的操作：1）开发算法，以确保频谱访问协议依赖的频谱传感过程的正确操作； 2）开发流量监控工具，以确定认知无线电设备的通信活动不当； 3）开发新形式的抗干扰沟通形式，以确保面对干涉的认知无线电通信继续可靠。研究工作是跨学科的，从统计工具到网络流量分析到通信理论，以支持认知无线网络的安全运行。该项目中开发的算法和协议是通过系统原型制作和实验工作补充的，旨在确保开发的技术适合在实际无线系统中部署。
