项目摘要

The ability to expand research frontiers through system deployment has been hindered by a lack of experimentation frameworks that can be used to safely and accurately evaluate new algorithms and network protocols at scale. This is particularly true for anonymous communication systems, which are generally understood to be among the most secure ways to communicate online, but are difficult to experiment with because (1) they are designed to be resistent to observation and (2) experiments must be crafted very carefully to ensure they do not endanger the systems' users. This project develops the Anonymous Communication Experimentation (ACE) framework, a novel open-source software platform that enables privacy researchers to better understand and experiment with anonymity systems. ACE supports the construction of large, realistic, and high fidelity simulations of anonymity networks. ACE allows researchers to run existing software on top of a virtualized network, allowing them to safely and accurately evaluate the effectiveness of new attacks and defenses, and experiment with new protocols and algorithms before they are deployed in live networks.This project aims to promote the development of new algorithms and techniques for more robust and private communication by providing a framework for development and testing. ACE significantly advances the state-of-the-art in network simulation by providing: (1) an application emulation component to facilitate the execution of language-agnostic processes in support of website fingerprinting and censorship circumvention research; (2) a lightweight network simulation component that allows dynamic changes in support of location- and network-aware anonymous communication; (3) an interposition component to hook together the emulated processes with the simulated network; (4) a deterministic simulated virtual kernel that emulates Linux system calls; and (5) parallel and distributed execution components to ensure that ACE is accessible to universities and research labs that lack large server infrastructure. We will also develop a user interface, a toolkit to model inputs and visualize outputs, and a data repository to share and archive results.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

通过系统部署扩展研究前沿的能力受到了缺乏实验框架的阻碍，这些框架可用于安全准确地大规模评估新算法和网络协议。这对于匿名通信系统尤其如此，匿名通信系统通常被认为是最安全的在线通信方式之一，但很难进行实验，因为（1）它们被设计为抵抗观察，（2）实验必须非常小心地制作，以确保它们不会危及系统的用户。该项目开发了匿名通信实验（ACE）框架，这是一个新颖的开源软件平台，使隐私研究人员能够更好地理解和实验匿名系统。 ACE支持构建大型、真实和高保真的匿名网络模拟。 ACE允许研究人员在虚拟化网络上运行现有软件，使他们能够安全准确地评估新攻击和防御的有效性，并在部署到真实网络之前对新协议和算法进行实验。该项目旨在通过提供开发和测试框架，促进新算法和技术的开发，以实现更强大和私密的通信。 ACE通过提供以下功能显著推进了网络模拟的最新发展：（1）一个应用程序模拟组件，可促进执行与语言无关的进程，以支持网站指纹识别和审查规避研究;（2）一个轻量级网络模拟组件，允许动态更改，以支持位置和网络感知匿名通信;（3）将仿真进程与仿真网络挂钩在一起的插入组件;（4）仿真Linux系统调用的确定性仿真虚拟内核;以及（5）并行和分布式执行组件，以确保ACE可被缺乏大型服务器基础设施的大学和研究实验室访问。我们还将开发一个用户界面，一个工具包来模拟输入和可视化输出，以及一个数据存储库来共享和存档结果。这个奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
