SkyF2F:Censorship Resistant via Skype Overlay Network

摘要：

Internet censorship is on the rise as an increasing number of countries and companies block or monitor access to parts of the Internet. Many censorship resistant systems have been proposed, which rely on deploying many access points to the censored domain. Therefore they face the problem of discovering available nodes and deploying a large number of nodes. Opposite to many access point approach, we present a system building on existing overlay network, a low-cost solution for circumventing Internet, called SkyF2F. SkyF2F is a plug-in for Skype client that allows users to establish a covert communication tunnel across Skype overlay network. We describe the design, a prototype implementation and security analysis of SkyF2F. Our security analysis shows that SkyF2F can successfully circumvent several sophisticated censoring techniques.
