Abstract of SWEET: Serving the Web by Exploiting Email Tunnels

 

SWEET: Serving the Web by Exploiting Email Tunnels.Open communications over the Internet pose serious threats to countries with repressive regimes, leading them to develop and deploy censorship mechanisms within their networks. Unfortunately, existing censorship circumvention systems do not provide high availability guarantees to their users, as censors can easily identify, hence disrupt, the traffic belonging to these systems using today’s advanced censorship technologies. In this paper, we propose Serving the Web by Exploiting Email Tunnels (SWEET), a highly available censorship-resistant infrastructure. Through experiments with a prototype of our system, we find that SWEET’s performance is sufficient for Web browsing. In particular, regular Websites are downloaded within couple of seconds.

Conclusion

In this  paper, we presented SWEET, a deployable system for unobservable communication with Internet destinations. SWEET works by tunneling network traffic through widelyused public email services such as Gmail, Yahoo Mail, and Hotmail. Unlike recently-proposed schemes that require a collection of ISPs to instrument router-level modifications in support of covert communications, our approach can be deployed through a small applet running at the user’s end host, and a remote email-based proxy, simplifying deployment.
