TC: Medium: Collaborative Research: Novel Forensic Analysis for Crimes Involving Mobile Systems

TC：Medium：Collaborative Research：针对涉及移动系统的犯罪的新型法医分析摘要：我们的项目将极大地推动调查用于贩运数字违禁品的移动设备的法医方法。虽然目前的方法和立法主要关注逻辑标识符，但我们将设计、评估和部署新的取证技术，专注于移动计算的一致和可跟踪特征。此外，我们的工作将在了解这些环境中个人隐私的限制方面发挥重要作用。我们将开发新的无线电指纹技术，以检测无线电低级部件中存在的识别信息。我们寻求从这些过程的准确模型中获得全面的理解，以便我们既可以确定匿名性损失的关键原因，也可以研究新的对策。我们将开发新的流量分析技术，以确定加密Web流量的来源。我们的重点将放在真实世界的流量场景上，在这种场景中，背景流量是存在的，整个互联网是一个潜在的来源。我们将使用我们部署的两个大型室外和室内无线试验台，在现实世界环境中对我们的方法进行实证评估。我们的研究将直接协助执法部门调查儿童性剥削图像的网络贩运，展示可信计算的可用性。我们将把我们的结果传播给针对儿童的互联网犯罪特别工作组和马萨诸塞州警察。此外，该项目将确定研究途径，允许在John Jay(一家为少数族裔服务的机构)获得学士和硕士学位的学生继续在马萨诸塞州大学阿默斯特分校攻读博士学位。

TC: Medium: Collaborative Research: Novel Forensic Analysis for Crimes Involving Mobile SystemsAbstract:Our project will significantly advance forensic methods of investigating mobile devices used for trafficking in digital contraband. While current methods and legislation focus heavily on logical identifiers, we will design, evaluate, and deploy new forensic techniques that focus on consistent and trackable characteristics of mobile computing. Additionally, our work will play an important role in understanding the limits of personal privacy in these settings.We will develop new radio fingerprinting techniques that detect identifying information present in a radio's low-level components. We seek the comprehensive understanding available from an accurate model of these processes so that we can both determine the key causes of anonymity loss and investigate new countermeasures.We will develop novel techniques of traffic analysis that determine the source of encrypted Web traffic. Our focus will be on real-world traffic scenarios, where background traffic is present and the entire Internet is a potential source.We will empirically evaluate our methods in a real-world setting by using two large, outdoor and indoor wireless testbeds that we have deployed.Our research will directly assist law enforcement that investigate network trafficking of images of child sexual exploitation, demonstrating the usability of trustworthy computing. We will disseminate our results to the Internet Crimes Against Children Task Force and the Massachusetts State Police. Additionally, this project will define research pathways to allow students who complete their BS and MS degrees at John Jay (a minority-serving institution) to continue their PhD work at UMass Amherst.
