Breaking Down the Great Firewall (part 2)...

As an update to my recent post about China's Great Firewall it seemed appropriate to discuss the methods for bypassing the Golden Shield Project. With the Olympics in full swing, and nearly halfway over, it is only a matter of time before China's government re-bans the websites and Beijing is again part of China's Internet censorship program. Chinese officials lifted their ban on certain websites after journalists were upset that many of the sites they needed to access were unavailable because of the GSP. Once the final medal is awarded it most likely won't be much longer before China is back to banning as much content as possible, so it is important to know ways to bypass the Great Firewall and maintain Internet privacy.

The following methods may seem familiar, as they are used for anonymous surfing, but they do in fact work rather well for circumventing the GSP and gaining access to banned sites.

• Anonymous Proxy servers: Anonymous proxy servers based outside of China can be used to access blocked content. The sites are blocked only to Chinese citizens and therefore if you surf using a U.S.-based proxy server then you can gain access to restricted sites. The website will read the IP address and give you permission to view the site. At the same time, the server will hide your IP so that anyone snooping the connection will see a person from Tulsa, OK surfing the Internet. As an added bonus a good proxy server will also encrypt the data being transmitted so that anyone spying can not view the information.
• Foreign companies can apply for a local website hosted in China. While this method does not apply to an individual user attempting to access a banned site, it is a method to bypass the Great Firewall since the company's content does not have to go through the Great Firewall (but the company does have to apply for a local ICP license)
• Using secure tunnels such as a Virtual Private Network (VPN). GSP can't filter secure traffic that is being communicated and therefore secure tunnels provide a way for users to access content and create sites that would otherwise be banned.
• Onion routing networks, such as Tor, can be used since it requires a network of computers to encrypt and mask your information. This method is, in essence, very similar to an anonymous proxy server. The major drawback of Tor is that you do not know who set up the anonymous connection you are passing through. As noted in an earlier post, you really have no idea who set up the connection and therefore anyone can invade your privacy through this trusted network. If a group of grad students and professors can do it, why wouldn't the Chinese government?
• FreeGate: a software utility created for Iranian and Chinese citizens to bypass any Internet censorship attempts by the government. The software finds open proxies, which are not blocked and can be accessed by any user, and penetrate firewalls. This useful tool is a bit controversial as it has been reported to be a Trojan virus.
• Reporters without Borders offers a "Handbook for Bloggers and Cyber-Dissidents" (PDF) which gives detailed information and tools for blogging and surfing anonymously. The handbook gives detailed instructions, including screenshots, for setting up a blog and remaining anonymous.
