As malicious hackers mount ever more sophisticated attacks, China is about to launch a new, “unhackable” communications network – at least in the sense that any attack on it would be quickly detected. The technology it has turned to is quantum cryptography, a radical break from the traditional encryption methods around. The Chinese project in the city of Jinan has been touted as a milestone by state media.
The pioneering project is also part of a bigger story: China is taking the lead in a technology in which the West has long been hesitant to invest. In the Jinan network, some 200 users from the military, government, finance and electricity sectors will be able to send messages safe in the knowledge that only they are reading them.
China’s push in quantum communication means the country is taking huge strides developing applications that might make the increasingly vulnerable internet more secure. Applications that other countries soon might find themselves buying from China.
So, what is this technology into which the country is pouring massive resources?
