A Blocking-Resistant Method for Anonymity System Based on Proxy and Data Hiding

Anonymity systems have been widely used to protect the privacy of the Internet users. Generally, the users should login to a central server before they join the system. Such action brings a risk that the attackers can block the system by cutting the connection between the user and the central server, which will deny the users from the anonymity service. In this paper, we present a design scheme based on the open HTTP proxies that can resist the block against the central server. In our design scheme, we hide the data in the HTTP protocol, by which to resist the block against anonymity system as well as hide the communication information in transmission. Through some simulation experiments, we had been collecting the open HTTP proxies from websites for tens of days and transmitted messages through them. The result shows that the proposed method is feasible and effective.
