Censorship continues to be a big concern for China

A group of computer experts from the University of Cambridge claims that they are now able to circumvent the censorship mechanism that China uses to block unwanted content from reaching its citizens. Certain words are banned and certain websites are also banned. A user sitting within the country's network will not be able to reach websites for which the government has deemed inappropriate. China itself has defended its right to police the Internet for its citizens many times.

The group of researchers say that China's firewall is based on a a series of Cisco routers and the products work by censoring keywords. When a user wishes to access a websites that's banned, the router returns reset packets to the foreign website, severing the connection -- the data transmission is stopped at the foreign end-point. Using this bit of information on how the Cisco routers work, the researchers were able to find their way around the firewall by creating a system that ignores the reset packets sent by the Chinese routers.

Along with their discovery, the researchers also found that it was possible to create a denial-of-service (DoS) attack from within the firewall using the router's own blocking mechanisms. By masquerading the source IP address of a banned website to one that's within China's network, the researchers are able to ban users from within the network from accessing a Chinese government website for example.

Richard Clayton, spokesperson for the laboratory at the university told reporters that the researchers had reported the findings to the Chinese Computer Emergency Response Team.

Whats worse... people accessing some nasty shiznad on the internet or the Mother Government censoring everything we view/read on the net???

They already have the mainstream media sown up. Thats all censored at the highest levels... Where do they stop? How much longer will we be truly free to express ourselves? Or is freedom of speech already gone and forgotten.

We have to hang on to our civil liberties. As Benjamin Franklin once said "They that can give up essential liberty to purchase a little
temporary safety deserve neither liberty or safety."

China do censor, the US gov do spy (NSA & co) and Google keep traks of your file with the desktop tool...
A lot of governments around the world have defined that the internet is "potentially bad" because terrorists can freely communicate and kiddies can download movies and infringe copyrights.
The point is: if someone build a wall, someone else is gonna build a ladder to get over it...
Actually there is some sort of panic because of all the illigal-immoral-forbidden stuff on the internet but no solution can apply.
In Switzerland ISP are obliged to keep the e-mail headers transiting their servers for 6 months because of lawfull interception laws.
But what if the guy organizing a bomb is communicating with encrypted mails ? Too bad...
You see ? 99% of the suspicius mails are coming from small-fishes and the 1% who would be really interesting is encrypted and nobody can look at it.
It is a complete waste of resources, money and time.

People will be able to change this, not technology.
