Collaborative Research: CT-T: TRIESTE: A Trusted Radio Infrastructure for Enforcing Spectrum Etiquettes

大多数商用无线设备不提供用户可访问的底层特性（例如，来自模数转换器的原始波形电平样本）。然而，最近，研究界将注意力转向了认知无线电的开发，它将向研究人员和开发人员公开协议栈的较低层。尽管这种灵活平台的前景非常好，但也存在一些严重的潜在安全缺陷。很容易想象，认知无线电可能成为一个理想的滥用平台，因为协议栈的最低层将以开源的方式向程序员开放。建议的项目将重点放在两个重要的组成部分，以建立一个整体的解决方案，以确保软件无线电的可靠运行：首先，研究小组计划开发工具来量化在认知无线电网络中频谱礼仪政策被滥用的程度，其次，研究小组计划研究识别这种频谱滥用的方法，这对于驱动异常检测和响应机制是必要的。总的来说，这项工作的广泛影响集中在认知无线电代表一种新兴技术这一事实上，在这些高度可编程无线电进入公共市场之前，需要开发安全机制。

Most commercial wireless devices do not make lower-layer properties (e.g., raw waveform-level samples from an analog-to-digital converter) accessible to users. Recently, however, the research community has directed its attention towards the development of cognitive radios that will expose the lower-layers of the protocol stack to researchers and developers. Although the promise of such a flexible platform is great, there are also some serious potential security drawbacks. It is easily conceivable that cognitive radios could become an ideal platform for abuse since the lowest layers of the protocol stack will be accessible to programmers in an open-source manner. The proposed project addresses these concerns by focusing on two important building blocks needed in constructing a holistic solution to ensuring the trustworthy operation of software radios: first, the investigating team plans to develop tools to quantify the degree to which spectrum etiquette policies are abused in a network of cognitive radios and, second, the team plans to investigate methods for identifying such spectrum abuse, which is necessary in order to drive anomaly detection and response mechanisms. Overall, the broader impact of the effort is centered around the fact that cognitive radios represent an emerging technology that requires security mechanisms to be developed before these highly-programmable radios reach the public market.
