Many are the people who, in the face of the attacks suffered on the different platforms, advocate the development of much more robust security systems than the current ones. It is not surprising since, as it seems we are used to seeing, it begins to be strange the day that there is no talk about how a certain company has suffered an attack and the data of millions of its users have been leaked, hundreds of millions of dollars in bitcoin ...
Without a doubt today we are talking about a very delicate subject since it is not an option to stop communicating, something that should be able to protect everything, or eliminate the dangerous basis on which the internet that we know today has developed. Because of this, it is especially important not to think about all the attacks we have suffered in recent months, but rather to look ahead and find a workable solution to this terrible problem.
The Chinese Academy of Sciences succeeds in testing its quantum encryption in metropolitan fiber optic networks
A possible solution to this terrible problem in which it seems that the privacy of any user hangs in the balance when we browse any page, something that, unfortunately, it seems that we have become accustomed, is to use encryption systems for all our messages much more secure.
With this in mind, today I want to talk to you about the work that scientists and researchers are doing at the Chinese Academy of Sciences They have just shown with real tests that it is already possible to use a quantum encryption key to achieve this objective of offering a much more secure communication system than the current one.
As a detail, at this point I would like to tell you that, although it is not the first time that a system like this has been successfully tested, what the researchers led by Professor Jian-Wei Pan have achieved in their evidence is to show that can be used in current commercial networks.
The Chinese Academy of Sciences has been working on this type of encryption for more than 10 years
If we stop for a moment to contemplate the progress that this project has made over time, it is fair to note not only that they have been working on this issue for more than ten years, but, for example, last year they set up a videoconference between China and Vienna using quantum encryption as a security element.
A few weeks ago it was possible to go a little further, since have made their platform work by making use of the multinode metropolitan fiber optic networks installed in Beijing. Thanks to this and its possibilities in terms of scalability, the work has been extrapolated so that the platform can work in more stations, so many as to create the largest quantum network to date, being, according to some experts, the perfect example of a network of intercontinental communication governed by the norms of quantum computing.
This network makes use of a quantum distribution key that uses photons to ensure the unconditional security of the network
To make this quantum encryption platform work, researchers have had to develop a complete methodology that is capable of creating 'keysultra-secure coding, which are known by the community as quantum distribution keys or QKD (acronym in English).
The main difference between the use of this type of cryptography with traditional methods is that, instead of basing the entire architecture on the inability of a computer to break security by calculating a user's private key, such as was done until now, this platform uses a quantum distribution key that uses photons to ensure the unconditional security of the network.
Thanks to this interesting advance, scientists have managed to determine many of the necessary bases to finally achieve completely revolutionize the age of communication Since, they have not only managed to develop a quantum key to encrypt a complete network, but more importantly, to transmit all kinds of encrypted signals through fiber optic networks.
