Tor是一个强大而重要的工具,为世界各地的用户提供匿名和审查抵抗。然而,在Tor中部署新服务非常困难-它主要是代理和隐藏服务-或者灵活地应对新形式的攻击。相反,由于可编程网络的最新进展,例如提供可编程网内中间盒的网络功能虚拟化(NFV),“非匿名”互联网服务正在以前所未有的方式蓬勃发展。这项工作旨在通过将可编程中间盒引入到Tor网络中来缩小这一差距。在这种架构中,用户可以在愿意的Tor路由器上安装和运行复杂的“功能”,进一步提高匿名性、攻击弹性、隐藏服务的性能等。我们提出了一个架构的设计,Bento,它保护中间盒节点免受它们运行的功能的影响,并保护它们运行的中间盒的功能。Bento不需要修改Tor,并且可以在实时Tor网络上运行。此外,我们还概述了如何显着扩展Tor的功能,以满足用户的匿名需求,并灵活地应对新的威胁。
Tor is a powerful and important tool for providing anonymity and censorship resistance to users around the world. Yet it is surprisingly difficult to deploy new services in Tor---it is largely relegated to proxies and hidden services---or to nimbly react to new forms of attack. Conversely, "non-anonymous" Internet services are thriving like never before because of recent advances in programmable networks, such as Network Function Virtualization (NFV) which provides programmable in-network middleboxes.This work seeks to close this gap by introducing programmable middleboxes into the Tor network. In this architecture, users can install and run sophisticated "functions" on willing Tor routers,further improving anonymity, resilience to attack, performance of hidden services, and more. We present the design of an architecture, Bento, that protects middlebox nodes from the functions they run and protects the functions from the middleboxes they run on. Bento does not require modifications to Tor, and can run on the live Tor network. Additionally, we give an overview of how we can significantly extend the capabilities of Tor to meet users' anonymity needs and nimbly react to new threats.
