Abstract:
While Internet access to certain sites is blocked in some parts of the
world, these restrictions are often circumvented using proxies outside
the censored region. Often these proxies are blocked as soon as they
are discovered. In this paper we propose a browser-based proxy creation
system that generates a large number of short-lived proxies. Clients
using the system seamlessly hop from one proxy to the next as these
browser-based proxies appear and disappear. We discuss a number of
technical challenges that had to be overcome for this system to work and
report on its performance and security. We show that browser-based
short-lived proxies provide adequate bandwidth for video delivery and
argue that blocking them can be challenging.
