Chinese created a network of communications that can not be attacked by hackers!
A Chinese city has successfully tested a computer network that can not be attacked by hackers, in the context of Beijing's concerns to counter spying, generating hopes of commercially deploying quantum communication systems, the Financial Times reported.
The city council in Jinan, a city in eastern China, said Monday that local government departments will start using the quantum communications network at the end of August, Mediafax reports .
"We intend to use the network for information on national defense, financial data and other areas, and hopefully be a pilot project that, if successful, can be used in China and around the world," said Zhou Fei, deputy director Of the Jinan Quantum Institute.
Test results are an additional incentive to implement the Beijing-Shanghai quantum network under construction. The Jinan City, located between Beijing and Shanghai, will be one of the data distribution centers.
Quantum-encoded communications networks (QKDs) are much safer than electronic systems currently used on a large scale. A classic communications channel, such as the phone or Internet cable, can be intercepted from the outside without the transmitter or receiver realizing it. In the case of intercepting a quantum network, the transmitted data undergoes changes and the administrators realize that something abnormal happens. In quantum communications systems, cryptographic codes or passwords are used between users, and the data becomes encrypted. If the code is accessed from the outside, the transmitter and the receiver realize and do not use it anymore.
The Beijing-Shanghai system would have the longest terrestrial quantum network, more than 2,000 kilometers away, for financial companies and regional administrative institutions. The tests consisted of sending ultra-busy data between 200 different terminals in the Jinan region through a network covering hundreds of square kilometers. In addition to securing financial transactions, the quantum network will make it almost impossible for any foreign intelligence service to intercept China's communications.
China's leaders are preoccupied with protecting national cyber space since transparency activist Edward Snowden has revealed sensitive US data and multiple attacks. In this context, the Beijing government intensified research projects in quantum technology. "China has made notable successes in quantum research. It is amazing what China has done in quantum research projects that would have been too expensive to carry elsewhere," says Tim Byrnes, expert at Shanghai University of New York University Campus.
Beijing was another success in June, when a quantum satellite - the world's first - managed to send a message to Terra through a quantum cryptographic communications channel. "Quantum systems have been able to be included in China's commercial sector more than in other countries, so Beijing is likely to overtake Europe and the United States in the field of cunical communications," says Tim Byrnes.
In Switzerland, Austria and Japan there are quantum communications networks of low level, mainly used by universities, for research.
