提案#：CNS07-22856PI(S)：付新文；格雷厄姆，史蒂文；哈尔弗森，托马斯；Streff，Kevin机构：达科他州州立大学麦迪逊，SD 57042-1799标题：核磁共振/Acq.：达科他州立大学研究和教育信息保障基础设施项目建议：该项目获取用于存储和分析收集的数据的计算设备，用于信息保证(主要是匿名研究的流量分析)，解决需要广泛模拟、网络流量的精确定时控制和测量以及大量数据和数据分析的问题。这些设备支持解决对国家安全至关重要的问题的项目，包括：匿名协议的退化及其对策。改进基于TCP的匿名通信的服务质量(Qos)，以及。匿名受限的Tor匿名通信网络中的服务质量路由在前人工作的基础上，系统地研究了基于流的匿名通信系统中的流量分析攻击，涉及统一不同的匿名度量。该研究借鉴了前人在基于流的匿名通信系统中对传输控制协议(TCP)性能进行的理论和实验研究。由于系统可以忽略TCP流量的特征，部署的匿名系统(如Tor)遭受严重的吞吐量下降。(ToR的服务器加载策略往往会产生瓶颈。)更广泛的影响：加强信息保障研究和教育，基础设施有助于将安全和隐私研究纳入课程。有关隐私、匿名通信和流量分析的新课程正在开发中。这项工作还促进了与地区行业的密切联系，主要是在银行和医疗保健领域。该州的其他大学，包括那些服务于美洲原住民的大学，也将受益。

Proposal #: CNS 07-22856PI(s): Fu, Xinwen; Graham, Steven; Halverson, Thomas; Streff, KevinInstitution: Dakota State University Madison, SD 57042-1799Title: MRI/Acq.: An Information Assurance Infrastructure for Research and Education at DSUProject Proposed:This project, acquiring computing devices for storing and analyzing collected data to be used for information assurance (mainly, traffic analysis for anonymity research), addresses issues requiring extensive simulation, precise timing control and measurement of network traffic, and large amounts of data and data analysis. The equipment supports projects that address issues critical to the nation's security, including:. Degradation of Anonymous Protocols and Countermeasures,. Improving Quality of Service (QoS) of TCP-based Anonymous Communication, and. Anonymity Constrained QoS Routing in the Tor Anonymous Communication Network.The project, based on previous work that systematically studies traffic analysis attacks in flow-based anonymous communication systems, involves unifying different metrics for measuring anonymity. The QoS research utilizes previous work in investigating Transmission Control Protocol (TCP) performance theoretically and experimentally in flow based anonymous communication systems. Since systems can ignore characteristics of TCP traffic, deployed anonymous systems such as Tor suffer from severe throughput degradation. (Tor's server loading strategies tend to produce bottlenecks.)Broader Impacts: Enhancing information assurance research and education, the infrastructure contributes to integrate security and privacy research into the curriculum. New courses on privacy, anonymous communications, and traffic analysis are under development. The work also promotes close ties with regional industry, mainly in banking and health care. Other universities in the states, including those serving Native Americans, will benefit.
