Web Serving by Email Tunnels

Abstract

Exposed infrastructures on the Internet signify a serious threat to countries with suppressed powers, which leads them to develop and deploy review mechanisms in their networks. Unfortunately, the existing suppression system does not offer guarantees of high availability for its users because censors can use the current advanced suppression technologies to easily identify and destroy the traffic that belongs to these systems. In this article, we propose to provide services (SWEET) through the use of email tunnels, which is a highly available suppression system. SWEET works by encapsulating the traffic of users who have been reviewed in emails transported by public email services such as Gmail and Yahoo Mail. Since the SWEET operation is not restricted by any particular email provider, we trust that the acceptor should block email communications to undermine SWEET, which is unlikely because email is an important part of the Internet today. Through experiments in our system pattern, we exposed that the SWEET performance is sufficient for web surfing.
