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

大多数商用无线设备不允许用户访问较低层的属性(例如，来自模数转换器的原始波形级样本)。然而，最近，研究界将注意力集中在认知无线电的开发上，这种无线电将向研究人员和开发人员暴露协议栈的较低层。尽管这种灵活平台的前景很好，但也存在一些严重的潜在安全缺陷。不难想象，认知无线电可能成为滥用的理想平台，因为程序员将以开放源码的方式访问协议栈的最低层。拟议的项目通过侧重于构建确保软件无线电可信运行的整体解决方案所需的两个重要构建块来解决这些问题：第一，调查小组计划开发工具，以量化认知无线电网络中频谱礼仪政策被滥用的程度；第二，小组计划调查识别此类频谱滥用的方法，这是推动异常检测和响应机制所必需的。总体而言，这项努力的更广泛影响集中在一个事实上，即认知无线电是一种新兴技术，需要在这些高度可编程的无线电进入公共市场之前开发安全机制。

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.
